I currently have a 89 camaro with a 305 tbi, and I am putting in a 88 GTA TPI in it. I have hte motor all put in and buttoned up, but now I am onto the wiring. I have the computer and the wiring harness from the 88 donor car and need to know how to splice it into the factory 89 harness. I wish the harnesses just plugged and unplugged, but the guy I got it off of, just gave me the engine harness, and nothing else. Does anyone know how to do this or a good website or book with step-by-step instructions on doing this? I am a idiot when it comes to wiring.
