i have a 65-66 gmc truck and was wondering if the wiring is the same as a chevy truck that same year. my problem is that all the wiring diagrams i have seen on chevys say that the wires coming fron the drivers side harness go to the horn relay and the voltage reg then a wire runs accross the front of the radiator area to the battery and mine does not have a voltage reg and i am confussed on where the power goes in to the cab.any help would be great thanks.
