So.. the car is a 90 gts.. the ecu, we seem to think is a 92/93 3sgte ecu. The large white plug under the center console.. On the wiring harness this plug seems to be almost ful, yet the one coming from the dash is only half full.

I'm trying to get familiar with the wiring on the inside, as I didn't do it. The kid that owned it before me did it. I'll do a little more searching, but a little bit of help would be nice. thanks.

So what exactly is your question?

I think he wants to know what he's supposed to do since the wiring harness on the 3sgte is full and the harness on the car is only half full...? That's what I'm gathering.

I guess he realized half way thought he didnt need an answer?

it sounds like its already done, so I dont understant the question. Just as long at the pins match than it should be fine. The important one is the check engine light which is one of the purple wires.

Well.. I guess what I want to know is what wires need to be hooked up. What all needs to be changed in the interior.

Is the wiring not done? This what I did http://www.celicatech.com/gallery/files/9/0/IMG_0035.JPG
I found a plug from the clip with enough pins then cut off the 3rd plug from the clip and spliced this into the dash harness. All the wires with tape match the gts/5s dash harness there are only a few that dont.

The only reason I did it like that was incase I ever needed to put the 5s back in. There is no need to cut or splice as both 3rd plugs are there

Now this is my question... Is there supposed to be like.. half the amount of wires on this plug?

The only thing I can say is search for the pinouts for the 92+ 3sgte. Your wiring should be the exact same as mine. There are only about 3 wires that need to be repined on the engine to ecu the only other thing is to make sure the third plug matches. I dont know what the other guy did but it looks like a mess.

I think that one plugs in under the glove box and deals with the hvac system.

oh and another hint the 3rd plug on the 3s ecu is the 1st plug ont the 5s.
