chasebays vs wiringspecialties

[jlmillionaire]

Hi all, im in the market for a new wiring harness,i had jgy customs do my first harness as it turns out im very displeased with there work. I really like the look of the chasebays harness and if i do something once i dont want to change it in the first place like do it rite the first time!! i just want to know if anyone has experience with chasebays before i go spend the 700 bucks, on the other hand i can save like 300 if i go to wiring specailties ive spoke to yury on the phone hes a real nice guy and i heard really good stuff about his work and he has the brand new harnesses in stock compared to the 2 to 5 week wait time chase offers if anyone can help me out that would be awesome thanks guys!!!!

[r34sr]

i have the chasebays ps line kit for my 240sx, and the engine bay brake line replacement kit....while there stuff is nice, its way overpriced for what it is....looking back , i would not have wasted the money, i would have simply made my own lines which would have been very easy.

[240sxKouki]

Good thread, I have been debating this same issue as well, I will be looking forward to hearing what people have to say. As of now, I am also leaning toward Wiring Specialties..

[ka24debt]

i have the wiring specialties harness.. it has diff dash adapters if u ever had to swap chassis's, comes with different pigtails for different mafs. super awesome, clean connectors, consult wires are hooked up too. id def. reccomend it you wont regret it

[jlmillionaire]

sounds like people are very happy with wiring specailties maybe ill save the couple hundred and i believe there in stock but i still want feedback on people who dealt with chase.

[projectblak]

Man wiring specialties FTW.. Best product purchased for my s14 sr... Fit like a glove and everything works flawlessly.... And Yury is always there when u need help

[jlmillionaire]

How long did it take you guys to get the harness from yury? like i said ive spoken to him a couple times real cool dude

[leung]

Another vote for WS. Their stuff is legit and fits perfect, and as mentioned have quick disconnects for different maf's. Very clear instructions as well. I got mine within a week of ordering if i could remember. I'm sure chase bays is top quality too, and that you can't go wrong with either one.

[projectblak]

How long did it take you guys to get the harness from yury? like i said ive spoken to him a couple times real cool dude

Ordered mine Friday came in the mail Tuesday

[rellik27]

S14sr into s13 from WS fit perfect and delivered in like 4 days.

[jlmillionaire]

yea i think im gonna go ws and save some money and not have to wait btw fuck jgy

[Relentless240]

Chasebays has lousy customer service....

[turbociv910]

granted WS is cheaper, is because is is made out of cheap split loom and electrical tape, and is not a high quality sheathing like CB. Its all preference, if your looking for a replacement harness, go WS, if your looking for a harness that adds bling and cool points and unlimited options to add or take off, go with CB.

[zenki14]

i would say ws just because when i ordered the ps kit it took almost 3 months to get it andthe 3 e mails i sent got back to me with the exact same message being a general statement towards a long wait for my order

[1slicktwo4oh]

I have a WS harness it works great...just like Oem...I made one like cb w/ the pricey wire sheathing looks great but took me forever to lighten,shorten,tuck and solder all the wires but in the end i saved my self $800+...So it was worth all the time I spent working on it..cb is for show not really necessary..money saved can be spent else where

[slider2828]

WS I think was one of the original guys here on zilvia.... I think back when heavy throttle.com was on board...

[CamryOnBronze]

WS hooked me up with a free engine harness for my car, and the quality is awesome. Yury is a great guy and has been nothing but helpful to me. At the same time, I have close to $1,000 worth of Chase Bays product and have not had any issues with them either. Both companies were cool enough to hook me up and have been great with customer service, so I really don't think you can go wrong either way.

As for which harness to choose, I think it is more about what you are looking to accomplish with your bay. If you are just trying to get your swapped car up and running, or care more about an OEM replacement, go with WS. If you want the tucked look and are into the mil-spec connectors, go with CB. You can make the WS harness look "tucked" pretty easily without much modification as well.

[blueshark123]

Pretty much what he said^ I like what chasebay does but they do have a long wait most of the time on customer service seems bad. If i didnt know how to wire and wanted something clean and tucked not oem i would go with chasebay or actualy hit up jordan innovation on here he does the same for less. If you just want your car to run good and look like a oem harness go with ws.

[redline racer510]

personal experience
WS= minimal asthetics more for function, great customer service
CB=geared towards asthetics, pricey, long wait time, sub-par customer service.

Both do the job just different ways of doing it.

[ghetto180]

Yuri from WS is a cool guy spoke with him too, but opt for something nicer and CB was not the route i went with, I am stationed here at Ft Bragg and know some 240 guys here, they did my one off wiring for $350, that all included new plugs if broken depinned and cleaned out with option of military quick disconnect from the firewall (i shoulda got for another 75 bucks but didnt) and all wires rewrapped in this carbon high temp sheathing finishing with heat shrunk ends, the builder Luis spent 19 hours + building mine, only because i have a 98 kouki sr20det into a 95 zenki with cruise control, abs, and oem ac cause i have the cody ace ka24de ac conersion to retain factory ac, and all features, shortened and redid my igniter wiring to relocate to my kickpanel by the ecu to keep it from the elements, rerouted my maf plug and wires across my firewall to the turbo side, it took almoust 2 weeks because i was the guinea pig, he has never retained ac and turns out the kouki harness is different and needed a UK plug which he got for me no charge, it goes on and on, but if anyone is intrested this is the best and better than chase bays for half the price, also he is testing it and wants to personally install it this weekend to make sure he sees that it works, sorry long story but was worth the wait, this is including transmission harness too. will try and get pix up this weekend when installed, Bare Metal Garage out of Fayetteville, NC, oh by the way he gives u a copy of ur harness on cd or flash drive and what he repinns if needed so like wiring specialties, u can add z32 maf later or whatever and will change it out just ship it to him, awesome quality and great work

[Hoffman5982]

I had to wait a few months for my WS harness, and half the time Yury was stringing me along.

Just saying...

[CamryOnBronze]

I sometimes feel that people don't understand the nature of a product like a wiring harness produced by a small company...

[bkg775]

I had WS and i loved it my friend got one for his Sr swapped s14 and it was all jacked up but i loved mine so he just had a fluke accident i guess

[JDM_Tuner]

Chasebays has lousy customer service....
+1, they forgot to send me part of my order...lol

Ive been running wiring specialties for the past 2yrs and ive never had a wiring issue, and i wouldnt spend $$$ on a chasebays harness that your most likely gonna tuck like everyone else anyways, so you might as well go with Yuri's harnesses and use the extra money for other stuff

[Hoffman5982]

I sometimes feel that people don't understand the nature of a product like a wiring harness produced by a small company...

While I get what you're saying, stringing me along was not something expected by a small company and is not acceptable.

[future]

How about to wire a lsX?

WS doesnt do ls swaps

[towlie]

SR swap, no?

SR20DET Swap Engine Harness Wiring Diagram Guide SR SR20 (http://www.frsport.com/SR20DET-Swap-Engine-Harness-Wiring-Diagram-Guide-SR-SR20_t_26.html)

Problem solved.

[RB180sxChris]

WS it is! I was debating between the 2...now I know what I'm getting...

[merks]

For LSx hit up Jordan innovation.

Super cool dude. We have been talking about how he is going to do my ls1 harness.

[future]

Ill hit him up and let you guys know. I have a harness for a ls1 that was in a s14. I need it rewired for a s13

[blueshark123]

I personally had problems with wiring specialties but that was a few years back when heavy throttle was around. what a pain that cost me. But i hear good things as of late, so i hope thats still not the case.

[CamryOnBronze]

While I get what you're saying, stringing me along was not something expected by a small company and is not acceptable.

Sorry, didn't mean to make the seem solely directed at you. I wasn't completely sure what you meant without hearing more details. I think people sometimes expect parts like this to be on the shelf and at their door two days after they press the order button, forgetting that these are usually small companies that don't have the capital or manpower to keep something like this in stock at all times.

I for sure agree though, didn't mean to make it sound like I was ragging on you specifically.

Lol gotcha, sorry for coming back as defensive.

I completely agree. The whole BallerBolts ordeal a few weeks back was a perfect example.

The ONLY reason I was upset with WS is because he told me it'd be done at the end of the week when in reality it was about 2-3 months later. With that said, What I received was exactly what I ordered. Top notch quality and literally took under 30 minutes to install. It's good to not have to worry about old brittle wires

[newslidz]

I have delt with cb and have had them forget to send stuff of mine. and its a call and follow up sorta thing until you receive it. there are some people like CamryOnBronze (http://zilvia.net/f/members/camryonbronze.html) that wont deal with many problems because its like freaking toretto on f&f when your car is out its golden and everyone pours in to get what you have.

[tinys s14]

Got my wiring done for my rb by yuri... Came out official. +1 for worrying specialties.. I also got a couple parts from chase bays n I def regret buying some of their way overpriced stuff.

[low n slow]

It took me three months to get my Chase Bays harness, all the while they were telling me it would be shipped out in the next few days. When I finally did recieve it I hooked everything up and my car ran like a fresh load of dog shit on a hot summer day. I thought, 'no way it could be the harness', and proceeded to check and double-check everything on my swap. Talking to a friend a local meet he told me he bought a Chase Bays harness and had similar problems until he realized the MAF was pinned wrong. Chase Bays pinned his MAF on the wrong three pins (wires were pinned on the left 3 slots rather than the right). So I decided to check my harness. Sure enough two of the wires on my MAF were backwards. Repinned them and she fired right up and drove off into the sunset! What a headache that was after resetting my timing twice, checking multiple MAF's, etc. Funny that they did the same thing to another locals harness.

I had also ordered the Chase Bays fuel lines. The fuel filter I had received had a cracked flare fitting so I sent Chase an e-mail. He assured me the filter would be in the mail and on the way soon. That was 3 weeks ago, I have since sent a few e-mails and received no response. :smash: Classy guys....

[sexcii-zenki]

For LSx hit up Jordan innovation.

Super cool dude. We have been talking about how he is going to do my ls1 harness.

Ill hit him up and let you guys know. I have a harness for a ls1 that was in a s14. I need it rewired for a s13

i want my harness made by jordan inno def lemme know how their customer service is and turn around time... since WS dont make my harness and chasebay too pricey...

[Chase Bays]

Low N slow email me directly [email protected] your filter & line shipped last friday. Chase is in and out of the office so much and his tasks require him away from his desk a lot but I'm always here to answer questions and fix problems like these.

It gets pretty crazy around here trying to answer every phone call and email in a split second, we are rapidly a growing business and sometimes our suppliers are the ones not keeping up. I can assure all of you I work with a sense of urgency. We have gotten more circuit boards for our CAMI research board to ensure that our harnesses are triple checked. Our harnesses are all 100% hand made so there have been some mistakes in the past. I believe with any product from Chase Bays Harnesses to iPhone's, this is the case.

What everyone has to remember is our quality control from functionality to aesthetics has a great amount of attention to detail, start to finish. We don't have our harnesses outsourced to a manufacturer and in turn you get a harness made exactly for your car and your motor, made by enthusiasts like yourself. People who build it as if they were building it for their car. This is such an important thing to us, and I believe it will make Chase Bays a lasting company.

Turn around time can differ, we have so many different options and harnesses. If we have to source out a core harness for you if you don't have one (if your harness requires a core) We've set a new system in recently to be 100% better about letting our customers know to exactly where there harness production stands, to the put of annoying you ;)

If you have any questions or need anything else let me know.
Thanks,
-Logan

Who is that best at s13 swap 2jz-gte engine harness? i'm not worry about the price!

[Ramonesfreak2010]

Two of my friends got the Chase Bay harness for their SR and both of them had their maf connector pinned incorrectly making them run super rich and not run properly. Hopefully they fix that issue...

I had my harness done by Taylor Durdan.

[S14Driftr91]

I got my harness from WS.. called yury up one day and drove out to his house the next. He's an awesome guy and if you ever need help with a question or have a problem he's super easy to get a hold of which is really great because getting through to some companies is nearly impossible. The harness is loomed nicely and looks amazing. Only problem I had was that a few branches off the main line were taped too high so I had to re-tape it. Like people have said if you're going for oem look then WS is the way to go. I haven't heard much about the CB harness although I do love that nylon or whatever its called, loom job :D

Here's some pictures of mine when I first got it.

[S14DOOD]

A buddy of mine has a CB harness in his civic hatch and has alot of problems out of it. I had used rywire before on a harness and loved it never had any problems out of it at all. My buddy is still using the rywire harness.

[thenooblet]

I have a ChaseBays harness for my LS6 and it's top notch. They told me it would take about 3-4 weeks to make and I got it in about 2 1/2. But like someone said they're customer service could be better..

So +1 for ChaseBays from me. No experience with WS

[blueshark123]

I have seen alot of nice work from rywire, but I never really seen anything besides honda stuff

[jlmillionaire]

does wiring specailties use china made plugs

[89JDM240sx]

I have the WSP harness for my Rb25 and very happy with it... I was real happy with because their customer service was good and delivery was fast

[JoshGentry]

I have a WSP harness for my rb25 S13. Very good quality. And if you're not tech savvy, they give you VERY detailed instructions. They also know their stuff. I called them a few times to figure out which wires are which for certain things. Have pen and paper ready because they will tell you without hesitation. Good stuff.

[jlmillionaire]

Thanks guys im gonna get the lowering harness from yury too i might as well hes gonna hook me up anyways!!!

[doublestitch180]

For LSx hit up Jordan innovation.

Super cool dude. We have been talking about how he is going to do my ls1 harness.

I would be EXTREMELY careful purchasing anything from CB.

Jeff Jordan is the only guy you'll need to go to for just about anything from just a simple wiring
harness to full on chassis/engine electrical systems from scratch. Very familiar with the
s-chassis and others as well.

Oh yeah...
his harness actually work the first time!

[PLAYERO_LOKO]

i've gone 5 1/2 months waiting on jeff to finish my damn harness to which i also gave him a 700 down payment and now he wont even answer any calls nor emails anymore!!!

worst guy in the world when it comes to producing, i've gotten nothing but empty promises from him and his staff... i highly recommend that you DONT go with jordan innovations at all! but if you wanna go thru the pain im in right now then by all means.

[PLAYERO_LOKO]

i wish i had gone with Yuri... now due to jordan innovations im screwed out of my LS2 and S13 harnesses! shouldve gone with my gut feeling instead of the fanciness which got me where i am right now. SMDH!

[Pblesh85]

Ive got a WS harness... or had on my last sr. I blew the motor and replaced it myself with no experience doing this before(aside from swapping engines. just never wired anything up before 100% alone). It was simple and straight forward. But I have had a few intermittent problems that I believe to be from the harness. I do not mean to talk shit or speak as if it is the quality of all of the work they produce. But I was not pleased with it and especially not aesthetically.

Anyway I blew the motor I swapped in after the first one went too. So I needed a running car and was not able to swap in my built sr I was waiting on from my last car. Well I live in tacoma and am friends with Doug and Eric from UPgarage. Eric has said he is not a fan of WS stuff as it always has "extra" connectors and is very non-specific. That is paraphrased a bit and cleaned up. Anyway if you have the access to someone that is capable and experienced. Have them build you a custom one. It will be tailored to your car and only have what you want/need. :2c:

Im not sure if anyone has been to UPgarage, but Eric is awesome with wiring and Doug is just awesome. Give them a call if your in the area.

Hope this helped somewhat

[jrizzo_240lsx]

Yury at WS is the man!!

He hooked me up with my LSx swap harness everything was plug and play took me about 45 min to install by my self...no splicing of any wires needed.

http://imageshack.us/a/img528/3140/20120809163411836.jpg (http://imageshack.us/photo/my-images/528/20120809163411836.jpg/)

[Sileighty_85]

Ive been doing business with Yury for almost 6 years now and have never had an issue with his harnesses. I'm still running a harness he converted for me in 07 still runs great!

[fliprayzin240sx]

I am using a WS premade harness for my RB25 swap into my S14. I got a couple of gripes about the harness but not that big of a deal. The harness is made to work on both S1 and S2 engines so it has extra plugs to so it's interchangeable between the 2. If you use it for an S1 engine, I'm supposed to cut the S2 plugs and tape the wires up. I just wish Yury would atleast give the option to have those plugs trimmed out prior to mailing it out. I havent chopped mine up, thinking down the road if I ended up parting my setup up, I can sell the harness.

This is probably due to my setup but only other thing (using on an S1 engine) is I wish the coilpack plug off the engine harness, is a tad bit longer and also the o2 sensor plug (probably 3-4 inches longer) to give you an extra slack. This is probably due to me running a Greddy Intake Manifold and routing the harness under the manifold...

[ixfxi]

i had no idea thats the same yury from heavy throttle days. thats a name i havent heard in a long time.

good to see he's still around

[RedSiBaron]

Jeff has been nothing but cooperative with me. He's building me a full chassis harness. This stuff takes time when it's the highest quality and when he does the work himself. What you have to understand is custom work takes time and he has priorities with big clients like d1 and time attack that are not only his primary advertising but also big clients that keep the doors open so he can even offer his services to people like us. He can't make a living making swap harnesses for hard parkers and wannabe drifters. His harnesses use the best materials, and to make it still affordable his profit margin is not high.

Custom parts take time 5 months is nothing, have patience. I've waited a year and a half for a head before. It's the nature of the beast.

[fliprayzin240sx]

i had no idea thats the same yury from heavy throttle days. thats a name i havent heard in a long time.

Yup, same same...he didnt exactly dropped off the face of the planet after HT closed shop. Definitely one of the first set of people who brought the SR swap and S-chassis out to the mainstream. They were the first folks that openly posted up a wiring guide for S13 SR swaps, that is still used today.

[om3ga]

I sometimes feel that people don't understand the nature of a product like a wiring harness produced by a small company...

A lot of work has gone into the harnesses at WS. I worked with Yury on a few ideas in the very beginning such as the quick change MAF adapter which allows the harness to come with both a z32 MAF connector as well as the stock MAF connector.

As seen in this picture posted by S14Driftr91

http://i56.tinypic.com/195r1k.jpg

The WS harnesses are as close to OEM quality as you can get. I recently installed one of the CA18DET harnesses and it fit like it was designed for the CA to go in a USDM chassis.

Wiring problems are something you do not want to ever deal with. I am glad to see a good amount of people caring about their wiring enough to start a thread about it.

Basically if you need an OEM style drop in harness WS is 100% the way to go.

If you need a custom or mil-spec harness Jeff Jordan is a great guy and does amazing work. You need to understand that he is a very busy guy since he is the one doing the work and can't hire and trust someone right away to do things the way he would do them.

I have seen a lot of his work in person and it is very well done.

Not too familiar with CB, they seem to make some interesting products but i am unsure of the quality. I have heard a lot of mixed reviews...

This is very well put. People need to understand that quality takes time. A lot of people are impatient and that is why you see a lot of thrown together engine swaps that run only half the time. Take a look at some of the build threads that have been going on for over a year or two. These are real quality builds.

does wiring specailties use china made plugs

Who cares where the plastic plugs are molded? Where do you think automakers have their plastic molding done?

The connectors are definitely OE quality and fit very well.

http://projectgarage.net/yahoo_site_admin/assets/images/CarBannerComplete.22500815.gif

[CamryOnBronze]

A lot of work has gone into the harnesses at WS.

For sure- I've had one of their harnesses on my car for a couple of years now, and the quality is great. Never had an issue with it, and Yury is always down to help me out!

[DJ-of-E]

I had many pigtails sent to me from WS and I usually get them within a few days. I can't think of any other company that would be able to find pig tails for my aging hardness on my KA and send them to me at reasonable prices.

To piggyback on this, just got done putting all my stuff together and finally attempted to fire up the car tonite. Shit started right up after 5 seconds of initially starting it up. FUCK YAH, WS IS THE SHIT!!!

[bllabong89]

^^LOL. FUCK YAH.

I also recently installed my WS rb25 to s14. I like the fact that it is interchangeable between series 1-2. If you blow your engine and get a deal on a different series...no big deal. You want to part it out but customer doesn't have the same series as you... no big deal. Tho I would like to have a CB or that style later on. That may be a winter project to take the WS harness and convert it to a quick disconnect style.

And shipping was fast, great oem quality and Yuri was awesome. Ya know same'ol same'ol :wan:

[ixfxi]

Who cares where the plastic plugs are molded? Where do you think automakers have their plastic molding done?

i care

sometimes it matters

sometimes it doesnt

if water gets inside a "sealed" connector, tell me how good it is.

[BiG MiKE86]

Anyone get a CB 2jz into s13 harness lately? Do they work right yet?

[fliprayzin240sx]

Not sure but I know MichealWinne is having issues with his Chaserbay RB25 into S13 wiring harness. He sent it back to them already to make sure the harness is good, they said everything checked out but his fuel pump still isnt priming and he has no spark.

That doesnt inspire too much confidence.... dammit their harness looks soo good but there are soo many unsatisfied customers

[fliprayzin240sx]

Honestly, I'd go WS. If you get him to rewire your stock harness, just hit him up first and see how much backlog he has so you got an idea how long itll take. But in all honesty, the pre-made harness he got are well worth the money.

I got WS harness car started in the first try awesome customer service!

[xZxCORE]

I don't know what the fuss is about between the two companies.. I have dealt with both on several occasions and I can honestly say right now that I would go with Chase Bays over Wiring Specialties.. Some one said there customer service is lousy which is complete bs. Chase is awesome and i have never heard of anyone having a issues from him or anyone else over there. They make amazing high quality stuff.

That being said if you can't afford the extra markup for a better harness then go with WS.. The quality is not the same as Chase Bays but there is absolutely nothing wrong with there harness. Better yet make your own and get some custom wiring experience, I don't care.. But overall Chase Bays is f***ing awesome!! I have had a s13 SR harness and now a harness for a LS3 thats going into my 14.. not to mention the brakes, power steering, radiator and fuel filter.. And the stuff looks amazing.

[jr_ss]

IM about to go out on a limb here and order a CB harness with the 10% off deal they got goin...

I ordered my VVL SR harness from them. Has yet to come in, but I will report when it does. I'm looking forward to it arriving.

[PLAYERO_LOKO]

Jeff has been nothing but cooperative with me. He's building me a full chassis harness. This stuff takes time when it's the highest quality and when he does the work himself. What you have to understand is custom work takes time and he has priorities with big clients like d1 and time attack that are not only his primary advertising but also big clients that keep the doors open so he can even offer his services to people like us. He can't make a living making swap harnesses for hard parkers and wannabe drifters. His harnesses use the best materials, and to make it still affordable his profit margin is not high.

Custom parts take time 5 months is nothing, have patience. I've waited a year and a half for a head before. It's the nature of the beast.

Well, the thing is when I get the product can I go for 5-6 months without paying?! Hell Nah, I'm forced to penny up immediately no questions asked... Why do you feel that the vendor should have that right????

Had I been informed that it would take over x amount of time/months do you really think I would've gone that route?! I don't think so, not to mention that I was told 2-4 weeks upon recieving my harnesses and down payment and I'm still waiting...

No where in the talks was it mentioned that if a D1 team or whatever they are, time attack, you name it... Should they be a higher priority than me or any other customer?! I paid with the same amount of money as those peoples why should they get better treatment with red carpet and open doors everywhere?!

[BlewByYou]

Bc they help advertise there business. That's what its all about and there testing and show off there product!! If you don't wanna be a sheep man up be a lion and make ur own lol. Jk

[PLAYERO_LOKO]

My brother, lol if I had the skills to wiring believe me and you both I would've gone that route instead of the $1500 route I took with Jordan innovations... Also the people who's running in D1, time attack, and any other type of racing actually get sponsored by the vendor not the way around!

Why would the teams pay extra money for something that they're going to help advertise?! Doesn't make sense, the sponsors aka vendors give the teams sponsoring or lower priced partsf in order to get their products known and purchased by the average Joe ... Unless I've missed something here, but the last time i checked, teams don't pay falken to run a car for them, its falken pays a team to have their product advertised with that team's car and driver or so it has only been since the beginning of sponsoring!!!

[PLAYERO_LOKO]

And for the guy who said that he waited 1 1/2 yrs on a head... All I can do is smdh! Not even tony momo who happens to be undesputedly one of the most talented and sought after for head p&p takes that freaking long!

If you can wait 1 1/2 yrs for just some head work then you my friend deserve a holiday named after you or a medal... At least hug!!! That's a 1 1/2 yrs free interest loan you gave that guy to charge you top dollar for what he did for you.

I'm not sure about you but nobody but my best friend would give me a free interest loan because any other time I went to the bank for a loan they made it cristal clear how much I was gonna pay in interest and to do that for someone who I barely know and give him such a freeby?! I'm not sure I can afford to do that!

But then again I have to work for my living, so that may not apply to most people... Just saying!

[dreamin240sx]

I have the ws harness for my rb and it starts second roll every time the best money i've ever spent.!!!!!!!

[Dumpedej]

I needed a harness ASAP for an event and he overnighted the harness and shot me a message to make sure I got it..amazing customer service and car started right up first time! WS FTW

[PLAYERO_LOKO]

lucky, lucky you!!! one day i will have this type of luck with things that have to do with my car... it will happen, it must at least once! lol

[fliprayzin240sx]

^^^First time this happened to me too. This was my first RB swap, everything worked out for me off the bat. I had a couple minor issues like busted water line hose and a loose starter but other than that, this was my smoothest engine swap ever. There was no troubleshooting, no chasing bad wiring, shitty ECUs or grounds...everything is working like the engine belongs in the car.

[ghoti]

I got a WS and just liked that i just plugged in and got it to start. No chasing wiring issues like the previous harness that was S13 to S14
that needed to be converted back to S13 to S13.Though I have to say I was not impressed at all by the quality. Plugs looked "cheap"
compared to the oem harness. Instead of having that plastic looking sleeving then electrical tape. It looks like just tape. Wiring
to injectors and the ones that go to MAF and PS are not long enough to tuck under the throttle body to make it look cleaner.

[240dream]

will wiring specialties being make a ka24de harness? i know chase bays has one but ws seems to have good quality work with better prices

[RedSiBaron]

i understand your frustration, maybe i just understand that when you have something custom made, you usually end up waiting when dealing with a shop that has bigger customers than you. I mean shit what im getting from him is more than twice what you put down and I could be bitching up a storm, but I am not, because the amount of money it would take me to get a similar harness is close to what i am spending, and on top of that I'd have to engineer it and build it, and honestly I wouldn't done with it by now either. I don't have the time to make a harness or the space. This is my project car, I have plenty else to do on the car while i wait for wiring. Next time ask more questions and don't expect mcdonalds service from a custom fab wiring shop. WS and CB are production product shops (yes they do custom), if you want it now, they cater to people like you.

And for the guy who said that he waited 1 1/2 yrs on a head... All I can do is smdh! Not even tony momo who happens to be undesputedly one of the most talented and sought after for head p&p takes that freaking long!

haha, it was a race head that id already had work on and was waiting on it from GUDE. at the time he was incharge of the saturn drag program motors for GM and had much higher priorities than my silly little race head. I sent him my brand new condition head. kinda stuck when its sent across the country. if i had known it would take that long i would have done it myself. shit happens and you learn. and what i learned is if i EVER send anything out, dont expect it back anytime soon. so far its held true. So unless I am in no rush, i dont send things out to other people to have work done, unless i can goto the shop.

Only thing im stuck on custom trans work, everything else i can do myself. and in the case of wiring, well I just wasnt in a rush and JI does really good work that i didnt feel like doing. plus id already done a custom full chassis harness for my friends car in 2011 and wasnt looking to do another for a while.

[om3ga]

i care

sometimes it matters

sometimes it doesnt

if water gets inside a "sealed" connector, tell me how good it is.

I hear you there, I can relate 100% when it comes to quality. I am the guy who buys multipe of the same parts and inspect their quality myself before making my decision.

I was more directly referring to the plastic than the weatherproof insulation on the WS connectors. From what i have seen with the WS connectors they are nice quality and all have the proper materials for keeping dust/water out. Yury would definitely not put as much time and money into this project to make poor quality pieces. The only issue i noticed with all of the WS harnesses i have dealt with is that the lower harness came with a different connector on the positive side of the battery terminal.

If you are really concerned i am sure Yury would be happy to discuss it with you or send out a sample connector. :)

[dopplganger1]

I would say both are top quality but it all comes to what your looking for I went with a chase-bays harness because I have not had any problems with them customer service wise and I was looking for a mil-spec harness with connector I will give a update when I get it and once it is installed and running

[ni5mo240]

i just went and fixed a chase bay harness was just ka in s14 but pins were missed pinned and chase bay was little to no help with any info for them or answering there calls i guess

[kuruptR]

Anyone deal with Rywire.com? They have an excellent product, but limited to S13 SR.

[jr_ss]

Unfortunately, you have to send the harness back for them to have most of the work done, if you wish you keep your warranty.

I have yet to have a problem with contacting CBays and Will has been super easy to deal with.

[angel mkiv]

I got the wiring specialties s13 sr engine harness and auto to Manual lower trans harness and love it!no problems after a couple years now

[Gar9854]

Anyone deal with Rywire.com? They have an excellent product, but limited to S13 SR.

I know they make top notch Honda harnesses but as far as a tucked harness ill be investing in a wiring specialties pro series harness.
Don't forget about Jordan innovations though

[garagelu]

Anyone deal with Rywire.com? They have an excellent product, but limited to S13 SR.

Rywire is the only wiring company I would trust right now. I have talked to Ryan in person and very knowledgable and friendly. People in the car community swear by him. Chase used to work for Rywire a while back and then started Chasebays. I haven't heard one good thing about Chasebays yet.

Rywire will custom make a harness for you so you may want to check that out.

[blueshark123]

I dont understand how chasebay is still around

[boxerpicker]

i have chasebays wiring. their wiring is nice but couple wiring was wrong like maf wire was flipped and oil pressure sensor wire is to short. it took them over 3 or 4 months to ship the wiring. they always keep saying to give em 2 more weeks.

[new2sr20]

i have the chasebays ps line kit for my 240sx, and the engine bay brake line replacement kit....while there stuff is nice, its way overpriced for what it is....looking back , i would not have wasted the money, i would have simply made my own lines which would have been very easy.

I agree with you. I went by their booth at IA in Nashville and was very unimpressed with their products. The wiring harnesses were nicely done but the rest of their lineup is stuff we can all make our selves very easily.

[VQMaxFan]

Never had a problem with any wiring specialties or rywire harnesses.

Wow, that was super helpful. I like how you explained your experience with Wiring Specialties...

Next time add something useful instead of raising your post count.

[Tw1st3d]

wiring specialties hands down thee best customer service I have had to date with any company I've bought performance parts from. Yury is the man and is willing to work with your needs if something needs to be changed on the harness. When I got my 1JZ to s13 harness one of the injector plugs was wired to short and would not reach. He payed the shipping costs fixed it and sent it back with a $20 gas card! Hands down THE BEST

[Rustys14]

^^^ Agreed wiring specialties is a great company. My ca18 harness is top notch and all of my friends run them on their sr20s as well with no issues. The piece of mind that comes with having a brand new harness and not having to deal with 20+ year old wiring is well worth the price to me.

I have also dealt with Chase Bays for their power steering kit and have personally had no issues with them. The same cannot be said for my friend though...

[eastcoaststeeze]

Wow, that was super helpful. I like how you explained your experience with Wiring Specialties...

oh here let me write you a personal novel just to make you happy.

Yury and Chris are more than extremely helpful at all times, if its responding to emails or answering phones they are always there to help. They go above and beyond for their customers, they were at a few club loose drift events and Chris was out taking his own time helping others get their cars back on the track so they could keep driving, using his/companies parts to help fix any issues people were facing. This shows that its more than a company just trying to sell things (prices on their products are awesome I think) but really are there for the people too. Also their turnaround time on harnesses are great as most are on in stock and ready to ship the same day.

[2muchboost]

Yury is the man. The guy spends more than enough time answering my emails and offering custom services for us maniacs.

[supersayianjim]

iam a ws bandwagon guy, brought 2 harnesses from then and so far very pleased!!

[EJ8 944]

I have a wiring specialties upper and lower harness, top notch products. They make a great product. Highly recommend them.

[Javier13]

wire specialties. Rather run my balls across broken glass rather than trust chase bay's wiring harnesses. Or hit up Mark Panic who does the wiring for a lot of Formula D cars. Such as Robbie Nashida, Ryan Tuerk, Rob Primo, and a few others. [email protected]

[OBEEWON]

I have wiring specialties. It is very nice BUT not worth the money. Also I had issues with the actual wiring. The guys were very helpful though and answered promptly until I had an issue. Then crickets. Would not hit it again.

[zerodameaon]

WS hands down, not only will you actually get your product but what you will get is a top notch quality harness.

[2muchboost]

Obee could you on me with some more details on the issues? Currently working with WS on a custom harness for my setup

[motteramm]

Another vote for Wiring Specialties from me. Quick delivery and amazing quality on the connectors and loom. Would buy again in a heartbeat. Especially because of all the quick disconnect options.

[TougeLabs]

I would love to hear more about your issues with customer service as well Obbewon.

[fliprayzin240sx]

Well, I had one issue with my WS harness that surfaced after I swapped my stock ECU to my PFC. For some reason, my PFC wouldnt power on properly, it would get stuck on the initialization screen. After troubleshooting it and checking with Yury every day for a good week and a half, it came down to a bad relay. The pre-made harness came with a generic relay, thats' bundled into the engine harness. For some reason, the relay would switch on but would not pass thru 12v so the PFC wouldnt get all the 12v it needs on all the switched power pins. 12V would go into the relay but for some reason, it's only passing thru 5-6v (yup, weird, never seen a relay do that). Swapped out the relay for a spare one I had, that I was using for my headlights and fixed the issue right up.

[beems240sx]

I have a WS AEM harness. No issues at all. Shipping was fast. Would for sure buy one again if needed.

[s14kkouki]

Wiring specialties. My ls1 fired up with no issues with their harness.

[mrturboextreme]

Just ordered a harness from WS for my s13 running an s14 sr. very happy with the customer service and support. Shipping was crazy fast

[wiring specialties]

Just seeing this thread for the first time. Thank you for all the kind words gentlemen.
Planning on a big year with many new engine and chassis introductions - LS1 (http://www.wiringspecialties.com/wsprprols1in.html), 2JZ (http://www.wiringspecialties.com/1j2jharness.html), 1JZ (http://www.wiringspecialties.com/1jzgte1.html), 300ZX, 350Z, BWM E36 and a whole lot more.

Again, thank you for your continued support. If you have any questions about our products, install, availability etc shoot us an email at [email protected]

[short-shifter]

I want to know what gauge wiring specialties uses on their harness because when I ordered a replacement pigtail for my injector it was an 16-18 gauge wire compared to the factory gauge which is like 12-14 gauge

[wiring specialties]

We use 20 gauge on the injector pigtail which is the same as OE.
If you have any questions, shoot me an email at [email protected]

[short-shifter]

this is what I'm talking about different size in the power wire

I dont see a problem with it. Does it do the job?

20 gauge will do the trick
Trust us ;)

Placed a order with Yuri at Wiringspecialists a few weeks ago, great guy! He replies to mails every day in just minutes, great support! Really looking forward to get the harness. RB26DETT race harness.

I hope he's able to help me with my Euro S13 as well (Equipped with CA18DET originally, now fitting a SR20DET).

One more for Wiring Specialties, Yuri, and Chris. These guys made me a kick ass harness for a rather unique setup.....I would do business with them again and again.

[ComicArtist]

Got a WS harness in my s13 w/s13 SR. Fits awesome, great quality on connections and solders, and I also dig that it's wired for single cam chassis and dual cam chassis dash plugs, as well as the maf pigtail. Definitely recommend.

Buddy's wife is also running one in her RB20 s13, never had a problem and she's been driving the shit out of it for 3 years

[fuerte]

Got a harness from WS had some problems on my end with wiring. Exchanged over 20 emails with Yuri answered each time in a timely response. I would recommend their products to anyone!

[vipergtsr1000hp]

I also bought a bunch of harnesses from Yuri, well 6 to be exact. Great guy and great product. He keeps you up to date with everything.

[ATLspeed]

Someone by 2jzgte CheapBays harness so I can switch over to Wiring Specialties!!

Going with chasebays was THE worst mistake I could of done. I emailed them containing the problems with misplaced wires and missing wires. Even sent it to them and every response was basically "It's fine"....I had to go through the harness and re-pin: o2 sensor, IACV, tps (missing a wire to control IACV), no relay to operate the IACV corretly (needs relay to open the IACV when the car is shut off), fuel pump wire was ran to ecu for god knows why...I need to find those emails! lol






Seriously lol

Been running my wiring specialities engine/trans harness for nine months. No problems and the install was easy.

Well I had a professional shop install my harness, they had no complaints.

Seriously lol

We apologize for the issues you experienced, can you help direct me to your email chain? I would love to research the issues you were having so I can become more familiar with it, I do not recall this scenario from memory.

We have recently vamped up our customer service and we are now available regularly to answer any and all inquiries. We also just launched a new website that was the source of many issues for the user and our company. We are changing the way we stock items and many of our other internal processes to allow the customer to have the best experience imaginable without any hassle. We aren't interested in leaving any customer unhappy, so we guarantee any harness and product we sell. If you are not satisfied, send it back to us and we will refund you. We think customer service should be that simple.

I noticed a comment on the first page when this thread began was spot on - and Yury I'm sure you can also relate. The extremely intensive and technical nature involved in building a custom engine electrical harness from scratch based solely on the options and information provided by a customer is unbelievably complicated. Virtually every chassis and engine has variations in components, and without accurate and detailed information, mistakes can occur. This is precisely why we probe our customers for as much information on a build we can get to ensure we build a perfect harness every time.

However, as you might imagine, even as much as we have tried to simplify the process of ordering a harness, it is impossible and irrational for us to expect our customers to know as much about wiring and variants as we do. So when an issue does arise, we like to jump in immediately and offer as much technical support as is necessary until the issue is resolved.

We love cars as much as you do. Every Chase Bays employee has their own personal build, so we also understand everything our customers feel and experience, and we want every experience regarding our products to leave the most positive impression. Otherwise, everything we work for is meaningless.

Feel free to email us anytime you have a question or concern and we will be happy to assist. We look forward to seeing you out there!

Why do people go for ecu harness in most case ? Is it because they do engine swap on different shell and need custom application ? or it's simply to replace 20yr old harness ?

I've got a 25yr old ecu harness and no sign that signal are not good ( considering its beeing tuned every year and no sign of anything wrong), but I'm doing a full overhaul and wondering if signal can get weaker with times or this is more true with winter-driven car that get corrode wiring due to winter salt and stuff like that ?

[supersayianjim]

Hi all, im in the market for a new wiring harness,i had jgy customs do my first harness as it turns out im very displeased with there work. I really like the look of the chasebays harness and if i do something once i dont want to change it in the first place like do it rite the first time!! i just want to know if anyone has experience with chasebays before i go spend the 700 bucks, on the other hand i can save like 300 if i go to wiring specailties ive spoke to yury on the phone hes a real nice guy and i heard really good stuff about his work and he has the brand new harnesses in stock compared to the 2 to 5 week wait time chase offers if anyone can help me out that would be awesome thanks guys!!!!

Yes, in most cases the ECU harness gets replaced during an engine swap because the original wiring harness would need to be modified anyway. It's often more cost effective to install a brand new harness vs spending time modding the crusty old one.

You really don't need to worry about wiring voltage drops. The wiring would need to be literally a few strands from severed to noticeably affect performance. The conductor will usually outlast the insulation. If you notice cracks or arcing discoloration in the insulation, it's time for repairs. Otherwise you'll be fine. I've never noticed any wiring issues due to winter driving (I haven't seen that many winters, either) but I have seen extreme heat (100+ daily) deteriorate insulation and plastic connectors at an alarming rate.
