cruiser54 Posted January 17, 2013 Share Posted January 17, 2013 Splits at the left taillight and goes across the back. Do you know about the ground behind the left taillight? Good idea to remove the screw, scrape to bare metal and reattach securely. Got a trailer wiring harness on that truck? Link to comment Share on other sites More sharing options...
Pete M Posted January 18, 2013 Share Posted January 18, 2013 you should also check the condition of the harness connector behind the driver side rear tire. Link to comment Share on other sites More sharing options...
