Help!! No reverse lights!!
 

Okay, I've exhausted all my efforts and knowledge, so hopefully someone out there can help. I have a 2004 f150 auto tranny with no reverse lights, all fuses are good, tested and no voltage to the backup lamps or center post of trailer plug, replaced neutral safety switch and harness looked okay...ran all wires and found no problems...am I missing something?!! Any help is appreciated.

Only thing I can think to ask is if you tested the bulbs?
