TPI harness and A/C
I'm doing a swap from a 91 TBI to a 89 TPI system. Its been a while since I've messed with TPI but I got some questions.
1. Do the existing AC plugs/wiring go to the current TBI ECU or is that seperate. How will teh AC be affected by going with the 89 TPI Harness?
2. Is there some place where I can see the pin outs of the harness/ECU?

Re: TPI harness and A/C
the computer only uses the a/c as an iput not an output i believe. uses the signal to adjust idle when a/c is on. if im wrong someone correct me. but i will try and get you some pinouts for the ecm on here
