| Round connector at the rear of the truck splits harness to tie into tail lights. If you have trailer wiring there may already be a pass through connector installed there. Take it apart here and see if fuse blows. If yes problem is forward. If no problem is back. If trailer pass thru is installed and problem is back disconnect it from service and try again. If fuse blows problem is in taillight pigtail. If no, problem is in trailer wiring. | |
