OK. Now I need some direction after not being able to find the answer in the wiring diagram.
RE: 1964 C-10
The gray wire from the gear indicator light socket in the steering column flows thru the dash wiring harness directly to the fuse box, where it is connected into the "GAS GUAGE EXT" along with the tan wire from the fuel sender unit (coming from the gas tank).
The gear indicator light will not illuminate, nor does a test light in the socket illuminate. My fuel guage works.
What's my next step in solving the gear indicator light issue?
