2019 F250 Super Duty Diesel with 5th wheel and RV package installed. The "round" trailer socket in the pickup bed works fine. The "round" and "flat" trailer socket on the rear bumper near the license plate does not work. Was intermittent for awhile but now does not work at all. Is there a different fuse for each one? Or do I have a bad socket on the bumper? Or, did something come loose near the spare tire under the truck?
Thanks, Gillie
as @Ltngdrvr said. The in bed harness plugs in between the feed from The front of the truck and the bumper mounted connections. Check where it is tied in first.
I would check the wiring harness that feeds the rear plugs and the plugs themselves. The fact that it was intermittently working and now not working at all makes me think moisture got in somewhere that it shouldn’t have.

That's the exact issue I had with mine last week. Turned out that the connection to the socket on the back side of the bumper had somehow came loose and had crud inside it. Visually the connection looked fine, but when I got ahold of it the plug slid off fairly easy. A good cleaning and dab of dielectric grease before I popped it back together was all it took. Of course, that was after I checked all fuses, drug out the test meter, researched for hours on the interweb, and about lost my mind.
