Reverse lights and trailer plug no workie

[Humvee21]

I just noticed today that my reverse lights are not working and neither is my trailer plug. I have checked fuses 15, 73, and many other various fuses that I cannot remember right now. All of which are good. Bulbs are still good but for fun I swapped them out too.

What else should I look for? Any ideas?

Un hook the plug from the back of the trailer connector. Mine had gotten water in it and was causing a ground fault. It blew a fuse also so it may not be the cause but worth checking.
