Under where the bumper bolts to the frame. Like, under the bed at the very end of the truck.

Check the whole wiring harness under it.

like 79 was saying there should be a junction where the bumper used to be where the wires are split up. sometimes p.o. will mess with them and sometime later it will just fail
