So I have a 1972 Camaro with a non-tachometer instrument cluster Speed Limit 150mph with fuel guage right next to it in the center is a colum shift P-R-N-D-L2-L1. set up. My question is does anyone have the exact wiring diagram for the plug that hooks up to the back and each wires function. I am actually in the process of making a wiring diagram schematic now with color coating and wire location. My only issue is that I do not know the exact funcitons for each wire. I have been tracing all the wires myself but just out of curiosity I'd like to know if anyone has one or knows what each wire does. I will post the wiring diagram I have made up to this point and then update it and repost it when I am done with hopes to help everone else out there who needs this!

 

closest i could find Camaro Wiring Diagrams, Electrical Information, Troubleshooting, Diagnostics & Restoration have you looked at buying a 72 factory service manual

 

Buying a Haynes manual is excellent value, if not the GM service manual set.
