Alright here's my question. I have an 87 TII harness sittin here in front of me and i have a few questions about it. I have an 88 GXL and i'm preparing for a turbo motor swap. Today i was lookin at the differences in the harnesses and i came across a possible issue. I Cant seem to find the CAS plug on the harness. Are the Turbo and n/a different alltogether as far as the CAS goes? I'm attatching a picture of what i have currently and maybe some of you can tell me if its the same or what not. Thanks in advance. I sure hope it does have the right plug.

 

Firt off, lets use the correct terminoligy: The Harness from the ECU to the Injecors is the "Emmisions Harness" The Harness that goes to the starter and the Alternator is the "Engine Harness".

Tha Cas Plug on the 87 TII is located on the Engine harness.

 

 

Also remember that the 87 T2 has a entirly different harness set up than the 88 T2, well alone the 88 NA cars.

The 88 was sort of a mutant year being a lot closer to the S5 wiring than the S4

 

So how jacked up is this going to be?

 

HMMM, If you have 3 weeks to wait, I can take your NA harness and convert it to a TII harness, it will cost though. My supplies aren't cheap and its a pain in the ***!

 

Derek, you might have to let him do that for you. Or if you can find one already made for a good price, do that.
