I have a 2004 F150. All lighting works except the reverse lights.
We have replaced fuse and the bulb. We also replaced the relay under the truck.

Can anyone tell me how to figure out what wires go to these lights. I am going to try to just add new wiring rather than looking for a cut or split.

Lights have not worked since accident where truck ended up in trees on side on the pole for a fence. We did not realize they were not working until to late for insurance to fix.

Thanks
