Resolved 1g Wire Harness question.

[wranglerunner22]

I know i dont have pictures but i will be as descriptive as possible:

I have a 94 nt talon, the owners before me did the swap, and cobbled the wireharness together with speakerwire(YES SPEAKER WIRE!) Anyways, I decided to replace the engine harness since i had the engine out to rebuild anyways. The harness i got is a 91 tsi awd, as far as i knew it would be fine, but here comes my problem, not too big of a problem but enough to be a problem.
As most of you are aware, the plugs that go into the ECU are yellow and then there is one white plug that goes to another small box to the right and further in past the ecu (right as in passangerside) And the other plug goes to the left right beside the ecu (driver side) the female connector is ziptied to the metal braceing that you bolt the ecu to, which is a 12 pronged plug, now here is my problem, the only plug i have left to plug in is a 7 pronged male plug. wondering how i have to splice this to make it work? or whats up?

The harness should be exactly the same, save for the bcs plug and such, as well as the knock sensor.
Sounds like you got an auto harness. I'm sure there's something more specific on what to do with the wires on here. I know I've seen this covered before.
OR it might be the abs control? abs is pretty rare on 1g's so I may be mistaken.
Maby it's the stock amp?

it looked like wires coming off of it were going to thinks like light bulbs and such, but i guess thats why im here asking this question, because i dont know. haha

 

[wranglerunner22]

anyone?

 

[boostin92awd]

It definately sounds like its an auto wiring harness and the extra plug is for the tcu.

 

[DSMTriad]

anyone?

Is there anyway you can get a picture?

The large female connector is in my cars interrior, the smaller male plug is what im having problems with..

This is the male connector off my origional engine harness. for size comparison

Ok I just went out to work on my wire harness swap. I have a 91 NT Talon, the wire harness I'm swapping in is from a 91 GS-T. They are not the same, you have to get a NT harness.

Whats different?
Is there TSI only options like sunroof/power door locks ect? I know there's the 'boost' gauge on the cluster, as well as the knock sensor. What else is there?

Are you serious? There are fully loaded NT 1gs running around.

G-Sensor
Boost control solenoid
Wastegate solenoid
FPR solenoid

The setup is different, you also have to remember if the car was an auto, abs, or has Cali emissions.

 

[wranglerunner22]

well, i know its 5 speed, and that it didnt have abs. so, i dont know, im just looking for a way around it. or even suggestions on where to look? because im stumped so far,

Does the both the connectors have the same color wires?

 

[wranglerunner22]

i think so, not 100% sure tho.
Ill have to check when im at home.

Yes I am serious. I don't see NT's very often sorry.

 

[wranglerunner22]

Hey i just looked at the wires, there are matching colors on both sides. And i looked at the origional harness, and nothing was merged to that plug as far as aditional wireing goes.

this is the complete picture of this bundle.

3 yellows go to the computer. the yellow and white one goes to that moduel, and the white male plug that is left is the one im having troubles with.

Ok, these are all female connectors and that module is the MPI Relay. Wait, I just realized something you can't use the AWD wire harness unless you bypass the injector resister pack. The turbos use 450cc low impudence injectors. Non-turbos use 240cc high impudence injectors. It will be easier for you to just find a NT wire harness, unless you plan on turboing your NT.

 

[wranglerunner22]

yes, my nt is turboed.

 

[imagine-02]

This is and was turboed when he got it. It's just that who ever did the turbo swap used speaker wire on the stock non turbo wiring harness to convert it to a turbo wiring harness.
What wranglerunner22 is doing is just swapping out the cobbled wiring harness for an actual turbo wiring harness.

 

[wranglerunner22]

THANK YOU! Yes that is exactly what the situation is

 

[wranglerunner22]

i guess im looking for someone that can guide me toward wiring it in. Anyone?

Reason for different wiring / connectors is explained here: 1990 Engine Control Harness - C67
