I have a 54 GMC with factory signal lights and need a wiring diagram to
finish my wiring. I found the wiring diagram for the signal light switch which was helpful but I did not understand what ribbed and plain was all about unless that was the color. I bought a Jim Carter wiring harness for a 54 GMC which was good except there is not much detail on connecting the signal light wires into the tail and stop lights . I think you need to tie into the brake light switch.Anyway a good factory wiring diagram on the signal lights would be helpful.
