Help!!!! I plan on swapping my trashed 305 with a 1994 LT1 out of a x-police (caprice/impala)? I have the wiring harness off of it but i don't have the 4L60E/4L80E trans that matches. I plan on using my stock 700R4 that came in the trans am. I don't have the money to fork out for a painless performance wiring harness so I plan on cutting up the one I have to run the 700R4. Can I use the 1994 PCM or do I need to get the 1993 one that was made to run the 700R4? Also any one got any wiring harness diagrams for the 1993 or 1994 LT1 wiring harness? Oh btw my car is a 1986 H/O Trans Am with a stock 4-bbl carb 305 and 700R4.
