s13 wiring nightmare need help! lots of pics

[rhdsilvi85]

ok so here is the situation.. I was working on my car and pulled the gauges out when i went to put them back in the gauges dont' work but the back lights work tho? so they are getting power, also I noticed my jdm climate control isn't working but has power because back light turns on as well.. i pulled the cluster out again and started testing the connections with a test light.. now I don't have power all the way across each plug in some spots I do some I don't I even started my car and tested for more power but didn't get any changes thinking my rpms or anything like that would create power for the plugs..

also I checked all relays and fuses and fixed the ones that were out and still nothing..

now for the wiring on the climate control is crazy I light tested the connectors and one of them when I touched it turned on the heat from my vents now when its plugged in its just blank screen? not sure if I fried it or not.. hopefully not since i've not really been messing with that at all.. I'm going to post pics of all the wiring and plugs also there is a whole mess of wiring where the radio goes i have no idea what these wires are any help would be great guys!!!

bump for help

[anti tyler]

you my friend walked right into the typical half assed wiring scenario.

the only reason those gauges, or anything for that matter, isn't working right is wiring.


what's the;
year:
motor:
etc..


did you do this wiring yourself? I just re-wired my entire center vent 3 gauge cluster, my custom switch panel, along with my ECU wiring. All because of a "glitch" we'll call it.
it's too easy to add too many wires to a single connection, butt connect something wrong, tape something wrong, connect something wrong, yadda yadda.

little more pictures of exactly where your connections are, as well as exactly what you're running as far as gauges.


i had a similar issue with my oil temp gauge not lighting up all the way. turned out to be a faulty connection in my battery wire. (gauge lit up 100% when attached to a brand new battery fresh off the charger)

as stupid as it sounds, it doesn't take much to cause a massive draw on your battery, causing it to not put out enough power to light everything up, (especially stupid when it all worked 100% the day, hour, even minutes before you took it out)

let me know if i didn't make an ounce of sense.

[rhdsilvi85]

its a 89 240sx se rhd conversion, black top sr20det. jdm gauge cluster is working power wise (lights up but no gauges work) found out how to test the gauges to see if its the wiring or the cluster ill get more connection pics... do you know where the master ground is for the wiring in the dash? maybe I might have pulled it out by accident. all my other gauges work my boost gauges and a/f gauge... im not sure if the kid before me spliced wires when connecting the rhd to lhd stuff.. im almost tempted to buy a full uncut chassis harness from japan and have it shipped lol. it's been nothing but a nightmare had a super draw killing the car so i put a kill switch on battery to help still don't trust the wiring yet so im going to have to see what happens... but what exactly do you want pics of so I can get them for you?

[ShadowMan]

I think you will be pulling your dash out. Sounds like a grounding problem.You might be lucky enough to retrace your steps but I think your dash is coming out in order for you to find it. Sounds like it's something you need to do anyway to see what else needs to be adressed in there.

[rhdsilvi85]

yuck not the answer i wanted to hear hahha the kid that i got this car from should not be allowed to work on cars its been nothing but a nightmare since i bought it... if i cant get it figured out I'll just run it during the summer with nothing working and then fix it this winter..

[rhdsilvi85]

here is some info I found and tested.... (now in the instructions it says the gauges when grounded out will max out if good... now i used a test light to ground out these as instructed in the instructions using the test light I wasn't able to get the gauges to move but just a little it from the bottom.. did I do this wrong? can i use something else to ground out that i better then that? please any help is needed on this... want to figure out if its wiring or gauge issues... before I start ripping stuff out.. thaks... here is the instructions

ok so looking at the cluster like in the pictures ill start with the left plug (plug on temp side of cluster).
red/black stripe- 12v constant power to the clock

black- one of the cluster common grounds

blue/black stripe- signal for temp gauge. ground this to chassis to test of gauge is working. The temp will max out if working properly

white/red stripe- alternator voltage dummy light

green- 12v ignition switched. this is what powers everything, bulbs gauges, everything.

yellow green stripe- for this plug only (there are multiple yellow/green wires on the cluster). seat belt dummy light trigger. not needed

yellow/white stipe-oil pressure dummy light trigger

yellow/purple- brake dummy light. rather low brake fluid or e-brake on. not needed in my case.

middle plug
green/yellow stripe- power to right turn signal dummy light when blinking

red/green stripe-high beam dummy light (power or ground, havent tested which one)

pink/black stripe- high beam dummy light (rather power or ground, whatever the red green isnt)

yellow/red stripe- tach signal from ecu. tach signal input for gauge

blue- 12v power for backlights when headlights are on

red/blue stripe- right side of cluster 12v power for backlights with headlights on.

yellow/black stripe- common ground for some gauges and lights

green/black stripe- unknown, doesnt go to anything on base model cluster. not needed (not sure about digital, but it goes go to an empty spot on mine that says 10k)

black- common ground for headlight and high beam dummy lights

third plug

red- unknown, not needed for base model but goes to "alb" so maybe the dummy light on abs cars?

black- ground for 2nd from right dummy light if you were to look at it from the front. ties into the ground for headlight dummies on middle plug deaper in the harness. not needed.

green/white stripe-2nd from right dummy light signal. not needed/unknown.

blue/maroon stripe- middle dummy light signal. unknown/not needed

red/blue stripe- low washer fluid dummy light. if you have jdm cluster the gauge will be the exhaust temp dummy light but when your low on washer fluid it will still light up. not needed in my case

yellow green- there are 2 yellow green wires on this plug. both go to speedo, one goes to a spot written in Japanese. the other goes to a spot that says 2p. i think the "2p" is the signal but not sure....need to do some research on this one.

red/orange stripe- backlight ground wire. this was a problem for me because i was getting 12v here and caused my fuses to keep popping and bulbs to get burnt

green/blue stripe-fuel sending unit signal. ground this wire to test if fuel gauge is working. it should max out the gauge just like the coolant temp gauge.

red/black stripe- low fuel dummy light signal/ dont think you need this wire for fuel gauge to work but havent tested this.

[EvilRB]

You have your answer in your post, regardless of what is actually wrong ( it sounds like a grounding problem FYI)

The owner before you did a hack job so If I were you I would pull the dash and just double check all the wires anyway just to make sure you don't have a fire down the road and there are no more problems. Kill it in one shot, might save you more time in the long run.
Thats what I did on my Cefiro but that just might be my OCD side coming out but man am I glad I did!

Good Luck!

[rhdsilvi85]

welcome to my new nightmare.. anyone ever done a jdm climate control swap? Need to know exactly which wires go where... he splicd a lot of crap

need help findng all the grounds too to check chassis grounds for the wiring... anyon know exactly where all thy are at?

[EvilRB]

I'm doing it on my Cefiro but it's the same as the S13.
Your just looks fucked!
But you'll be glad after your finished! I know I would be after seeing all that!

Here are the FSM's JDM and US versions
you will need to look at the S14 one for the Digital diagram.
It's the same as the S13 but not sure about the wire color codes I used a A31 diagram I found to rewire my set up. but placement was the same on the harness.

Manuals > JDM and European Cars > S14 Silvia - Zenki (SR20DET) - Nissan 240SX Performance Tuning (http://www.240edge.com/manuals/s14-sr20det.html)

Here is a youtube video also on the DCC install if it helps

S13 Digital Climate Control Conversion - Part 1 - YouTube (http://www.youtube.com/watch?v=2z5_PxGAiIU)

If you were local I'd give you a hand... good luck!

PS, Remember to heatshrink and soder everything!
You might as well spend the extra time to do everything the right way now than have electrical tape everywhere and have to do it again later.

[rhdsilvi85]

Yeah im going to be doing the soldering and shrink wrap cuz it was an ekectric tape nightmare... Im going to need to study youtube cuz this kids has wires going every where spliced... I cant find the grounds i found two and they were secure to chassis.. Do you know where more would be at for the gauges?

[rhdsilvi85]

Hey that YouTube video is set to private btw.

[anti tyler]

all previous posts aside, speed-reading through. my basic suggestions are as follows;
(Given that you're no master in-dash electrician)

#1) get yoursef 2 terminal blocks.
Something along the lines of this, for Constant +12 power as well as a Chassis ground
Lot of 3 RadioShack European Style Terminal Strips 12 Position Standard | eBay (http://www.ebay.com/itm/Lot-of-3-RadioShack-European-Style-Terminal-Strips-12-Position-Standard-/360629672676?pt=LH_DefaultDomain_0&hash=item53f7341ae4)

This is what I did, I mounted these in a secure place under my steering column, which feed both my dash mounted gauges, as well as my switch panel.

#2) draw yourself a plan for your gauge wiring. stop all this digging around, find where the gauges connect to the main harness, make a note of which wires came from where, and re-plan out how the gauges will be wired.

(I found this to be the most helpful thing ever. Not only have I had to do this to eliminate faulty ECU wiring, but it makes it a whole lot easier to track down where your wires are coming/going from.)

That's the two things I recommend at this point. Aside from finding all the diagrams you need for your wiring. Get all the info first. then make sure you have plenty of time and booze. hang out in the driveway, and tell the girlfriend/wife/fiance, to leave your ass alone for a day or two.

proceed with wire grooming.



*** after taking a second to scroll back up, I'm almost sure I've got your story mixed up. you're working on the gauge cluster right? not just some gauges (boost/oil/etc..) ***

still a good practice to do the above mentioned. my :2c:

[rhdsilvi85]

my stock jdm gauges aren't working but power to them works.. my aftermarket boost and a/f gauges work great spliced into some other stuff... as for the jdm climate control it lights up but nothing else works.. when I took out the dash I found a electric tape mess so I'm going to go back and recheck all the wiring and solder connections and shrink wrap...

[EvilRB]

Damn man, that video worked when I posted... and has been working for a few years!
IDK what happend?
Your just not a lucky guy! LOL!
I might need to stop talking to you before it rubs off! HAHA!

They all say the same thing basically but they have different pictures nd the wire codes and pin outs. You just kinda have to put them together for your needs.

Just remember to double check the connections that were already made as well.
Judging by the job the last owner did I would redo everything even if you think it looks good just to be sure.
Again good luck and have fun! ... well try...

[rhdsilvi85]

yeah I know I just watched it this morning too lol.. wtf... I just need guides to check the wiring done already... so I can go back and check it all.. before I start soldering... thanks for the help bro.. much appreciated hopefully I can get this thing on the street by june if I luck out.

[EvilRB]

Oh another thing, after looking at your pictures again your dash bar is rusted to shit and might be having trouble grounding.
I'd take it out and sand that rust off of it.
Spray it down wioth some paint and primer and then clean the grounding points again just to protect it and make sure it has solid contact to the chassis.
Not only will it look nice but it will protect it for the future and might be another source of your grounding problems.
Couldn't hurt right?

[rhdsilvi85]

does anyone hav diagram of the jdm wiring so I can see what goes where for the wiring? im confused i know this relay only has 3 plugs into it right now that doesn't seem right to me...
