What are these under my F250

[Luke'sScreenName]

I noticed these connectors under my 2016 F250. They're just in front of the rear bumper.
The truck did come with "Upfitters Switches" as an option and I'm thinking they are related? Any ideas?

Factory towing package?

Nope, not tied into the tow wiring but does all enter the same wire loom as it head toward the cab.

do you have the 5th wheel prep package? could they be for install a plug in the bed of the truck?

No optional prep package. I'd do that myself aftermarket but this is unrelated (I think).

just picked up my 2016 F350 I'll check underneath mine. I have the 5th wheel prep and I guessing that this is where the in bed trailer light plug in goes to

Could be integrated to the brake controller and the sway feature Ford uses.

Put a meter on them and see what shows up with the lights and brakes.

Looks to me like they are blank plugs in wired sockets. The plugs would except pins for a 6way trailer plug and trailer brake controller.. Just my guess.

I don't know what they are for but the definitely have nothing to do with the up fitters . I have read up extensively on the up fitters and wired things to them on several trucks. The wires for the switches don't go to the back of the truck.
