I have a 74 B100 Dodge. Have headlights and turn signals, but no side marker, brake lights, tail lights, or instrument cluster lights. Any idea's? This is getting old !

Hello and welcome. Have you checked the fuses? If the fuses are all good, inspect the headlight switch. There are few places where all those lighting circuits intersect, and the headlight switch is one of them. The action on the headlight switcj should be firm but not crunchy. If you feels crunchy movement when actuating the headlamp switch or if the terminals of the switch ro the wiring harness plug are corroded or heat damaged, the switch may have failed internally.
Had the same issue. It turned out to be a shorted wire in the steering column. I would replace the fuse and all lights would work. When I stepped on the brake pedal, the fuse would pop and all I would have is head lights.
