Im doing a TPI swap on my 72 chevy truck and i want to use the wiring that i took from the firebird. I was wodering if anyone knows where i can get info on modifying the factory harness myself (what wires and connections i need/dont need). Any help would be great.




:hail:

 

It's not as much fun as one would thing but, having wiring diagrams are essential to the swap. Knowing what wires go where is extremely helpful. At the same time, I elected to swap out the interior harness on my friends truck with one from a 85 & 86 camaro to update to a newer fuse panel and have the needed circuits prewired.

this is for an 86 camaro

it's a good starting point for getting the TPI harness sorted out
Also I have this which may/may not be of assistance...

They aren't very recent but, they're the newest I have right now and not much has changed since those have been taken due to lack of $$ & mostly time.
