the story is this-
Aircraft mechanic, always wanted to big pickup truck, bought a 1978 C-
20, stuck it in a garage for 10 years when he moved on the other things,Took it out of the garage, and the right turn signal didn't work. Jumped around the wiring harness from where some trailer hookups are taken off in the frame harness.
There are four lions coming down the frame harness: reverse lights, tail lamps, and right and left signals.
Things are working okay now except that I lost the right brake light and the right taillight is much brighter. Are the filaments in the two filament bulb different wattages? Did I get the wires reversed? Or is it some resistor in the light switch?
I put in a good GM light switch about a year before I parked it.
