I have no tail lights, fender lights or tag lights. all cab lights, turn lights back up lights and head lights work. I can not find what fuse to check in the owners manual they don't list a fuse for tail lights. I have checked the plug from the frame to the bed.
Tail lights on 2006 Ford F-350 Super Duty
Under the hood of the truck on the driver side fender is another fuse box. It's one of the smaller 10 amp fuses in that box.
