s14 SR20DET into s13 chasis - WIRING (I searched)

[2plus4plus0eq6]

Anyone know of a write up, link or anything about wiring up a s14 SR20DET with wiring harness into a 1989 s13 SOHC chasis.

I have gone through dozens of pages on trying to look for this (even on other forums). I know some people make a living off of this, but someone must have some information for free ;)

I know there are some connectors off of the harness which are not used, but which ones? I am not sure.

Any sort of help would be greatly appreciated. I hope this thread can not just help myself, but others that are in the same situation.

Thank you.

[Slidin240Wayz]

Send the wiring out. It will save you time and headache and possibly your car.

[2plus4plus0eq6]

no time. no money. how can no one know how to do this and explain to others on what to do?

[Typeone]

No time AND No money?!?!

Maybe you should take up another hobby... considering cars and/or racing require both!

Send it off, you'll thank yourself for it.

I agree I sent mine off to the Heavy Throttle Wireing Specialty Guys I paid only $125 for a Red top in an S13.

haha i coulda told you that would happen, no one wants to give any information due to the fact that its how they make money......

this is what i did

i went to drifting.com

ordered the wiring video that shows you how to wire s14 to s13 chasis for $20

wired it up........

now the car is just waiting for heater hoses..............they should come in today...... now i cant tell you if it worked for me cuz we havent tried to start it up yet... ill let you know by the end of the weekend if it worked......

[street240]

I dont think its an issue of people wanting to make money. I think its more of an issue, there are not of s14 into s13 rollin around. Those who do have the swap may not have seen the thread or are to lazy to post.

[brainfood]

its super easy, you just need to re-route power, s13 powers the ecu and engine harness from the fuse box under hood and s14 powers it from a relay under dash. That is the main difference. The instrument cluster wiring is the same just deloom the harness and follow the power wires from the s14 ecu relay and reroute them through the engine harness back out to the s13 fuse box and use the connectors off your ka harness. Other stuff is the same cut and lengthen maf wire and o2 wire. Need to search around for wiring diagrams of s13 redtop into s14 and then reverse. There is a write up of that swap, I did mine with just wiring diagrams its only like 4-5 wires not that bad at all.

[Casascacas]

Definetely send it out. I was gonna do it myself (s14sr in s13) and after looking at all the crap that's different between the s13 to the s14 i decided i'd bite the bullet and send it out to someone that has done it before.

Yury from Wiring Specialties is whom i went with. The guy knows his stuff and he'll help you in any way he can. It's been around 3 years since i had it done and if i remember correctly i paid around $260 or something like that with shipping.

SEND IT OUT!

[nrg]

do what brianfood said. i wrote it up on a piece of paper a few months ago. here's the scan: http://www.driftingisgay.com/img/s14sr_in_s13.jpg

all color match up btw. oh yea, there was a thread on this: http://www.zilvia.net/f/showthread.php?t=142928

[2plus4plus0eq6]

Thanks for the help guys.

The issue is not really about money and I don't have time to send stuff away. I have to get my car back on the road ASAP as it is my only vehicle at the moment. I'd also rather do it myself to save some cash and learn something at the sametime than giving it to someone else. When everyything is working fine and dandy, i'll probably just post some pics of the harness connections or something so this thread can be finally stickied.

For now, I'll try my best to follow your writeup NRG and probably order that DVD off of drifting.com as a backup.

For those of you who have done this before, would you be willing to shed some light on this for me and others or would you still charge an arm and a leg?

[2plus4plus0eq6]

1 more thing.. bwake_5, which video did you get? I just want to clarify.
The first one has a picture of a s14 motor I think so I'd assume that would be OK as well.

http://store.driftingshop.com/sh180sswandm.html
http://store.driftingshop.com/srwidiindvd.html

[bwake 5]

well we tried to get it running yesterday..... everything is almost done, butt when we hooked up the battery just to see if we could get power to the interior it didnt work..... so we are at a standstill for now

i got the video that said s13,s14,s15 motor into s13 chasis wiring........
read the descriptions of the videos. it will tell you, it is a really good video.

[nrg]

you must have done something wrong. wiring up the motor to make it work with the car shouldn't affect the wiring for the interior. The wires for those are at the fuse box and they plug right in. S14, it doesn't even touch the wires. S13 swaps, a few wires from the lower tranny harness (same power wires to the battery) plugs into the fuse box to give the car power.

[2plus4plus0eq6]

I found this. It might help.

http://www.nissanperformancemag.com/march04/240sr/

[bwake 5]

how would that help, thats for s13 to s13?

[The Riot Hero]

super easy, i did it myself on my own car in about an hour. i used the relays on the engine harness. you dont need to lengthen maf wires, just untap some of the harness and theres tons of slack thats bundled up under the tape, 02 sensor wires will need to be lengthened alittle bit.

[bwake 5]

super easy? what?

well maybe we are super retarded cuz we did something wrong.

no interior power whatsoever

[2plus4plus0eq6]

Did you splice the brown connector or white connector to the big ECU plug?

From what I have heard, its supposed to be the 6 wires from the brown connector from the KA harness, but for my car I only have a white connector that matches the wires. Maybe someone was colour blind or something.

I ordered that video so when I figure everything out, Im going to spill the beans so no one can make money on the wiring for this.

[bwake 5]

ORDER THE VIDEO for sure..... we got my car started tonight, we had the fuel lines on backwards. and missed a ground wire.... thats it!!!!!!!!!!!

now im runnin!!!!!!!!!!!!!!!!!!!

the video was perfect, good luck with the swap, that video made the difference for me,,,, soooo easssyyyy

[bwake 5]

I SAY THAT IF ANYONE HAS QUESTIONS ON HOW TO DO THE S14 MOTOR INTO THE S13 CHASIS THEN ORDER THE VIDEO ON HOW TO DO IT FROM

WWW.DRIFTING.COM (http://www.DRIFTING.COM)

IT WILL SAVE YOU I PROMISE!!!!!!!!!!! AND ONLY $20

[2plus4plus0eq6]

thanks man. im glad to hear that there is some hope. hopefully they will ship my video out to me today ;)

[2plus4plus0eq6]

Ok well i finally got my video after 3 weeks of waiting. Its pretty straight forward for the most part. The order they did some stuff and some things were confusing, but I think I've done OK for the most part considering I don't know shit about shit. If anyone could give a little bit of help, that'd be great.

The Link I previously posted about wiring from Nissan Preformance Mag was wrong. Similiar, but incorrect to the s14 SR20DET Into the s13 chasis.

I Also went over NRG's Notes; its a little different than what they said in the video. Actually a lot different. Not saying he's wrong. Maybe both ways are possible or I misunderstood what he was trying to say

Here is what I am supposed to hook up from the White KA Connector to the SR Harness & SR ECU Plug:

SR PLUG to KA

Orange - Orange/Blue (from ECU)
Red - Orange (from ECU)
Blue/Black - Yellow (coming from the harness)
Blue/Green - Blue/Green (Coming from the harness)
Yellow/Red - Blue/Black (from ECU)
Green - Green (from ECU)
Black - Black (from ECU)
Green/White - Green/White (Coming from the harness)

1. I'm supposed to match up the Green/White wires together from the white KA connector to the Green/White wire on the SR Harness (not from SR ECU Plug). The only problem is that I don't have a Green/White wire on my KA Plug, but I did find the wire on the SR Harness

And.. do I connect the 3 black wires from the KA connector to all of the black wires on the ecu? Aren't they all ground? I just need to clarify.



http://i84.photobucket.com/albums/k10/dylanw83/whiteconnectorka.jpg

2. I plugged in the KA Grey and Brown connectors that I spliced into my SR Harness - The ones near my battery. Now I am left with a bunch of connectors from the fuse box that I don't know what to do with. I'm sorry for my noobness, but I am trying my best. Are these supposed to go to my tranmission harness which I am to use from my KA or not connect these at all (which I doubt)?

The gray connector in the purple box has the wires:

Yellow/Blue
White/Blue
Green/Orange
Blue/Green
Yellow
Yellow/Black
Green/White

The black connector in the red box has the wires:

Black
White

The brown connector in the yellow box has the wires:

Light green
Light green/Red

The gray connector in the blue box has the wires:

White
Black/White

http://i84.photobucket.com/albums/k10/dylanw83/fuseboxka.jpg

This gray connector is coming off of the KA harness that is coming from the fusebox. The wires are:

Black
Red/Blue
Brown
Yellow/Blue

http://i84.photobucket.com/albums/k10/dylanw83/fuseboxka2.jpg

[2plus4plus0eq6]

3. Im not totally sure about this plug. Its coming from the chasis near the wheel well. Im thinking its a connection for my signal lights. It only has the wires:

Black
White

http://i84.photobucket.com/albums/k10/dylanw83/ka_near_fusebox_chasis.jpg

4. These 2 plugs are coming off of my SR20 harness. Im thinking they are my plugs for my ignitor. I will try and do some more research on this of course, but if someone can give me a heads up, then even better.

The wires for 1 plug are:

Light Green
Brown
White
Red

The wires for the other plug are:

Red/White
Red/Yellow
Red/Green
Red/Blue
Black

http://i84.photobucket.com/albums/k10/dylanw83/sr_ignitor_plugs.jpg

5. These 3 plugs are coming off of the KA harness and from a hole in the very corner where my ABS used to be. I was an idiot to not label some things when I was disconnecting and now I am paying for it. I've taken my ABS out and not sure if these plugs are for that or for something else.

The wires from the plug in the white box are:

Light Green/Red
Gray/Red
Blue
Yellow
Blue/Red
Black

The wires from the plug in the purple box are:

Orange
Red

The wires from the plug in the yellow box are:

Brown/Yellow
Blue/Yellow
Red/Yellow
Green/Yellow

http://i84.photobucket.com/albums/k10/dylanw83/ka_corner_plugs.jpg

6. These 2 plugs are coming off of the KA harness just before the fuse box. I don't have a clue what these are for and if they are important or not.

The wires from the plug in the green box are:

Red
Yellow
White/Red
Red/Yellow

The wires from the plug in the red box are:

Yellow/Green
Black/White

[sblack13]

leave the lower harness alone, you only need to worry about your main engine harness. Don't make things more complicated than they already are. A shop by me fixed someone who recently messed up on their wiring they cut all their wires by the fuse box

[2plus4plus0eq6]

Ya thats the thing Im not sure about. Do I connect all of those wires I have mentioned to the KA lower harness (is that the same as the tranmission harness?). I've also taken out a lot of crap from my engine bay like the ABS, A/C and other misc stuff.

[2plus4plus0eq6]

OK well.. some stuff finally started to click in my head. I was freaking out on which lower harness to use because I wasn't able to find my stock KA one, but now I have.

So this fixes some of my questions for now. I will probably be back asking some other stupid stuff in the next couple days. Thanks for your patience anyways guys.

[nrg]

ALL! of your lower harness plugs in. you do nothing with them but plug them into where they belong.

all those plugs into somewhere near the fuse block.

http://i84.photobucket.com/albums/k10/dylanw83/sr_ignitor_plugs.jpg
ignitor goes into those plugs

i dont understand how you can be so confused.
The gray and brown harness runs on the side of the engine bay. right beside the battery.
it goes from the engine harness, around the shock towers, under the coolant reservoir, to two plugs right beside the battery. That's the only plug you have to use. you just extend wires from the S14 SR20 F3 plug to that area.

[2plus4plus0eq6]

alright. thanks nrg. i realize what I had to do now. Im still not quite sure about the plugs near the corner of the engine bay, but I will try to figure it out on my own for now. For the ignitor plugs, thats what I thought, but I just needed some reassurance.

I have a q45 Ignitor chip so I got some information from heavytrottle.com on how to wire 1 of the plugs into it, but still not so sure about the other one.

Heres the link to the document. I have a q45 ignitor chip by the looks of it.

http://srownersclub.com/faq/faq_ignitor.asp

On the plug that is supposed to go to the coil packs, the wires are:

Red
Red/Green
Red/Blue
Red/White

But, the wires on the plug on my SR harness are:

Light Green
Brown
White
Red

What do I do?

[taylor_durdan]

youre in way to deep i think and arent looking at this in a manor that you should be... just send me the harness and let me make it for you. it will look better than factory and work 110%

[Monooxide]

What do I do?

You should probably do some reading into the FSM and I probably shouldnt help you. But, If you look in the FSM, the wires to the injectors and coil packs change at different plugs on their path to the injectors and coil packs. This is no big deal AS LONG AS THEYRE IN THE CORRECT ORDER. Which im sure they are.

[2plus4plus0eq6]

sorry man. I don't have another month to send stuff away. If you can help on here then great, if not, then thanks anyways I guess.

[mr_240sx]

well im also in the same boat as you.... ill keep you updated as im planning on trying to finish everything with the swap by monday afternoon.... so if i find answers to your questions ill help you out.

[2plus4plus0eq6]

sweet. its nice to know im not the only one out there like this lol. did u get the video as well?

[mr_240sx]

no i havent gotten it :( im pretty sure if i pretty sure ive done enough reading and comparing that ill be able to figure it out. plus it also helps a few of my buddies are good with wires so im sure well be able o figure it out.

[Monooxide]

Ok well i finally got my video after 3 weeks of waiting. Its pretty straight forward for the most part. The order they did some stuff and some things were confusing, but I think I've done OK for the most part considering I don't know shit about shit. If anyone could give a little bit of help, that'd be great.

The Link I prev.....

......Red/Yellow

The wires from the plug in the red box are:

Yellow/Green
Black/White...



1) Yes, the 3 grounds can go together they are just grounds. The Green/White IS NOT IMPORTANT unless you want to use the consult. Very Unlikely.

2) Bah, its so hard to answer this without having done mine yet which should be done tomorrow. Can ya wait a day? Was your car an Automatic? Where are these plugs coming from? SR Harness? KA lower Harness? SR Lower Harness?

3) Yes, that is very very much looking like the turn signal plug.

4) Yes this is your ignitor plugs.

5) I would assume theyre ABS...but I have NEVER seen an ABS 240....errr ok i lied never looked at one closely in depth.

6) Its so hard to any kind of electrical/electronics help over the boards.

Ill be doing my harness here tonight or tmw. K?

[2plus4plus0eq6]

Great, thanks for the help Monooxide. I'm hoping to get my car running by this weekend so if we're all in the same boat, we can help each other and get it done.

1. OK. I understand to connect all of the black wires from the KA plug that I cut off. Does that mean I connect them to ALL of the black wires that are on the SR ECU harness plug (because there are more than 1)? The video didn't specify.

2. I figured this one out and connected my KA lower tranmission harness. The only plug left to figure out is the brown plug in the yellow box which I don't know about.

3. I actually don't think its a turn signal plug. it goes through my wheel well and it looks like its connected to my braking system or something. Is this how brakes work? Anyways.. I think I hooked it up right to a plug coming off of my SR harness if I can remember. its a plug thats near the KA brown and gray connector that I attached to the SR harness.

4. OK so those both are ignitor plugs. I know how to wire up the 5 wire plug, but not sure about the other. Someone already said to look into my fsm and trace the coil pack wires. I'll try and figure that out, but it would nice if someone could just tell me which wires to hook up to my q45 ignitor chip if they have done it already themselves.

5. I don't have a clue about these plugs because I don't seem to have any connectors from the harness that will match up with them so I am a little scared. I am hoping that they were for my ABS because I took it out so I shouldn't have to worry about it.

[mr_240sx]

did you figure out where the plugs in #6 go? cause those are the only plugs left that i cant figure out. btw ill be working on trying to get mine running by monday afternoon so ill keep you guys posted if i find out a way.

[2plus4plus0eq6]

Yes I figured out number #5 and #6. Im actually surpised to see how many people veiwed this thread yet not as much help as I expected. Amazing, but anyways..

5. These plugs are used for ABS. If you took out your ABS like I did, then you don't need them anymore. Plugs as listed for anyone who wants to know.

Motor Relay:
Red
Orange/Blue

Rear, Right Front, Left Front Solenoid Valves
Blue/Yellow
Green/Yellow
Red/Yellow
Brown/Yellow

Actuator Relay:
Blue/Red
Green/Red
Blue
Gray/Red
Yellow
Black

6. These 2 plugs were on the SR lower Harness and you don't need to worry about them because The KA Lower harness should be used anyways like the so many people who have told me already. Thanks ;)

[bwake 5]

haha i dont understand anyting yall are talking about, my wiring was easy and strait foreward from the video

[bigOdom1]

so you didn't learn shit from your project. i guess i dont really care but you still paid to do it.

[mr_240sx]

the only thing is i dont have a ka tranny harness as i boght a shell with no engine. so i guess ill have to find the wires on the chassis harness and then splice them on?

[2plus4plus0eq6]

That could be really tricky to do with the SR lower harness. I would go to a junk yard and pick up a KA lower Harness from a 240. You will save yourself a headache because of all of those connections to the fuse box and such.

[mr_240sx]

well i spent a good 2-3 hours today with a buddy of mine trying to figure it out with sr tranny harness and after looking at different fsm's and comparing....im gonna locate a ka tranny harness and it should then become plug & play

[2plus4plus0eq6]

Ok well I finished most of my wiring today and tried to start it up, but no spark so far. I will keep you guys updated as I progress through this.

Here is a link to the thread I will be using for troubleshooting my start up problems:

http://www.zilvia.net/f/showthread.php?p=1441483#post1441483

[mr_240sx]

you ended up using the ka tranny harness right?

[2plus4plus0eq6]

ya.

The only weird thing is.. is that I can't find the plug for the speed sensor on my KA harness. I am confused as hell on that one, but it should still run without it, I would think right?

[mr_240sx]

yeah the engine will run without the speed sensor except you wont have the vvt-c. but isnt the speed sensor on the sr harness teh same as the 5th gear sensor of the ka harness?

[2plus4plus0eq6]

OK sorry, but I am a little confused about what you are saying.

From the KA harness I use:

1 plug for the neutral switch?
1 for the reverse switch?
and the other 1 for the speed sensor? (which is the 5th gear sensor)

Is this what you are saying? If so, could you please post a pic of the 5th gear plug on the KA harness so I know which one.

Is there anyone out there that can please clarify this for me?

Thanks


Note:

I know the KA trannsmission harness has 3 plugs (as far as I can find) and the KA tranmission has 3 sensors + the speed sensor:

The SR transmission has 1 less sensor than the KA transmission.

I tried to use the speed sensor from my KA on the SR Tranmission, but it didn't fit (The KA was larger). So therefore I had no choice but to use the SR one.

[2plus4plus0eq6]

I know I am bringing this post back from the dead, but I am just curious to know if you guys got your car running and everything. I am still wondering about the speed sensor wire.

[mr_240sx]

i just finally picked up my tranny harness sunday night and hopefully this week-end ill get a chance to plug it in and hopefully get everything working. ill keep ypu guys informed.

[2plus4plus0eq6]

I just wanted to say that I found my speed sensor wire. it was tucked away in the corner of the engine bay. Im gonna share some information that I shared with you already mr 240sx. hope you dont mind. I just want to help out.

This is for the transmission sensors:

The KA tranny has 4 sensors while the SR tranny has 3.

The sensors you will be using are the speed sensor, (neutral switch or reverse switch - I can't remember. I think both of the sensors are the same) and the 5th gear sensor. The neutral switch or reverse switch that I am talking about on the SR tranny wasn't able to be removed once the tanny and engine were in so I just left it because I think its the same as the KA one anyways.

The speed sensor from my s14 sr tranny was not the same size as the one from the ka tranny so I will just try and use the SR one but the other 2 sensors in the sr tranny were replaced with the one from the KA tranny.

You might need to cut some wires and splice the necessary connectors to them. Look in the FSM for the correct wire colors.

In the end, you will be left with 1 sensor connector on the KA tranny harness which is not connected to anything (which i think is the reverse switch sensor).

Here is a link I posted for wiring up a Q45 ignitor to the SR harness:
