Anybody know how to find the part number of (or get ahold of) a GM wiring harness blueprint? Specifically, I'm looking for one for the engine harness on a full-sized '71 Buick. I've emailed a couple of the wiring harness makers, and nobody has one (apparently nobody has asked about big car harnesses before...) If I could get my hands on one, it might be a help for the guys at M&H.
The chassis manual will give you a one-line on various systems, point to point. Conductor size & colour are included. Conductor lengths & connector style numbers are not. Let me know if I can help .
