79 flareside tailight issues

Hello, I am having an electrical gremlin in the back of my 79 150 flareside where I have turn signals, reverse lights, and brake lights but marker lights and running lights only in the rear dont light up I cut out all the bad wire from just before the chassis harness plug and ran all new wire to each tail light .... I get 12v to the marker/tail light until I hook the tailights up then it drops to nothing .... im pulling my hair out trying to figure it out ... any help is appreciated

100% rewired correctily? Are your grounds and bulb sockets 100% good? And is the headlight switch 100% also?
