That is for an '85. That's the trans I have. I need one for the '87 IROC TPI. I was told by a trans shop that the wiring is different.

Anyone have access to the diagram? the '86 is the same as '85 so that wouldn't help.

Thanks!

The wiring should be the same... .crawl under you car and look.
The 88TPi I put in my friends 72 truck with the trans from my 84 camaro all have the same wire colors (i.e. the 88 GTA lockup wiring is the same as the 84 SC Camaro the trans came from)

 

What the guy at the tranny shop was saying, was something to the extent of one of them uses 2 of the wires and the other trans uses 3. I just don't wanna end up shreding the TCC!

 

Sorry to bring this back from the dead, but I am still fighting this problem, but I WILL BEAT IT TOMORROW!!! Anyways my question is probably going to sound stupid, but since I am a not good at reading wiring diagrams I will ask. I pulled up the diagram and want to go step by step and trace the problem. Please someone correct me if I am wrong on any of this.

So lets start

The pink/black wire is HOT and comes from the fusebox to the BRAKESWITCH. Then a purple wire comes FROM the BRAKESWITCH to the torque converter plug that plugs into the transmission. This PURPLE wire is normally open meaning that it is normal groundeduntil the brakes are applied???? Then from the plug in the transmission comes a TAN & BLACK wire that splits to the ALDL connecter and to the COMPUTER that signals it to be GROUNDED or HOT??? Does the computer ground the tan/black wire

Is it usually straight to the computer(tan/black wire) or with a plug?
I have had my computer switched to SD from MAF(86 Iroc) and wondering did I forget to plug it in? Where in the harness is it.

Lastly, What is the best way to troubleshoot. Check ground here, hot there, switch here. whatever. Let me know. What should the wires at the plug be. The tan and purple when the converter should lock. oh yea, can the computer say it is locking the torque converter without a signal from the tan wire.

sorry for so long. Someone just bring me step by step to figuring out this problem.

Thanks for reading
