It really is not much wiring involved to make the engine run and charging system opperate.
What you might do is contact one of these wiring harness manufacturers and tell them what you are about to do and they will make you a harness that fits your application and send you step by step instructions for installation.
You could also go and buy a Hanes repair manual for the Camaro and use its wiring diag. to figure it out.
