Re: 70 fuel guage wire color? behind dash
My AAW kit has a tan wire between the fuel sender in the tank and the gauge. The original harness from 1970 was also tan for this circuit. Mine runs from the rear of the vehicle, across the floor pan in a flat, black rubber ribbon wire protector and then up inside a rubber tube next to the fuse block. It pops out of the rubber tube along with many other wires and they go various, as required places after that.
Yes, pink is typically a 12 volt positive wire that is only hot with the key on.
Lime green at the gauge cluster is the high beam indicator light. Regular green is the temperature gauge, if equipped.
