Not a whole lot of wires that are different on a 350 motor than a 54 motor with basic accessories. Just starting/ignition, sending, charging. 95% is chassis/body wiring.
If I see you are monitoring this I will offer more if you wish. I see you have searched and found info on another post. That's good. I recommend, as far as the Speedway Harness, that you move up to Part no. 91064022.
