If the running, marker and license lights work then so does the ground.


Find the round connector on the right rear that connects the rear light harness to the main truck harness and unplug several times to clean the contacts. You really need a test light because electricity is invisible. A quick check will tell you is power is even getting back there. The brake wire is the Yellow/Red stripe on the lamp harness and Yellow/Blue stripe on the main truck harness. There is a 10 pin connector under the pass seat... do the same thing to clean the contacts. The wire could be rotten or stone dammaged between here and the tail lights. Did I mention a test light??? :) Only $5.
