Wondering if anyone has a schematic of everything that has to be spliced into the gto's engine and transmision harness to make this work out. This is a first for me and im kinda worried about the swap and making everything work. Do i just have to run power to the ecm and make sure all the sensors are and plugs are connected? I figured there would be a writeup or book about it. I have done some searches but have only found a couple little things not everything. Thanks for your help guys.

 

Adapting the stock harness into the car is not really difficult. There are only really about 10 wires from the engine harness that will connect to the car. Half those are gauge wires. The rest are 12v constant and switched power etc.... That is all dependent on your particular harness.

Do a search for wiring diagrams for aftermarket harnesses. They will show you which wires are required. Then find the same wires in your harness and connect them the same way.
