trailer plug aux power not working

have a 2015 F350 Diesel with a tow package.
I have no power output to the Aux power pin in the trailer plug in the bed or bumper plugs. all fuses are good and relays are installed, no visible broken wires. I don't think it ever worked. now it is out of warranty.

Mine did the same thing. An easy and quick solution was to connect a wire from the parking light to the aux/brake connection to make my trailer brakes release when backing up. I finally figured out the problem with a loose connector.

Did you check it with the truck running, I think the ignition has to be on for it to power up, maybe even running.
