Hello,
I just recently bought a 1984 c30 3+3 dually. I am having some issues with the lights that I'm hoping I can get some help with. The cab top lights and the tailgate lights do not come on at all. I have checked every cab top light and they are all grounded with good bulbs. The wire comes out of the hole below the speaker and is connected to the headlight switch harness. Every other light on the truck works, the interior dome and floor light, dash lights, tail and head lights, side marker lights, turn signals, everything.

I only have one wire coming out the bottom of the tailgate for the tailgate lights and not sure if their is supposed to be another one or not? The one that is coming out is not connected to anything so I know thats one of the issues for the tailgate lights.
-Thanks for any help!
