all of my marker lights,blinkers and brake lights work except my passengers side rear tail light. it is dead. both bulbs are fine I even replaced them and still nothing. no blinker, brake or running light. So it has to be in the wiring, can anyone help me out with a wiring schematic for the tail lights? the truck is a 1996 2500
much appreciated!

 

Hmmm check the harness where it runs into the plug that holds the bulb and look for any damaged wires (frayed/broken), also chase the wires from the back of the truck to the front, Im sure sooner or later you will find a broken or frayed wire, fix it and see if that solves your problem, hope this info helps
