On my 2002 and 2015 I installed the 7 pin trailer harness in the area behind the taillight. I was wonder if it can be installed in the same location on the 2022 I have on order.
I like this area because I use my bed and Its out of the way

Thats slick location right there. Not sure you have access to the stake pocket on the newer trucks. I had the same issue on my 15. I bought a new plug and I cant remember where but I went to home depot and bought a box and made something that has worked great. I found out later that I could get one from Ford that was much nicer. You have to find a truck that has the plug and take the vin to the dealer so he can order the plug. I drilled a hole in the side of my bed so I could run the wires. so far after 6 years and it's still working fine. I put mine under the bed rails because I didn't like the location low on the sides of the bed. Mine has worked perfect in that location.

I sat down today and was going to order a B&W gooseneck and some air bags and a fe other things, But no one has part #'s for the 2022's

The factory trailer plug is basically in the very same area with the gooseneck/5th wheel option. If you don't have the option you can buy the OEM 7-pin connector and harness and add it for a nice plug and play installation and it does come with a template to locate and drill the needed holes. If the 2021 has room in the same location you pictured I see no reason why you could not do the same since you will have to drill holes anyway. I don't know if the part numbers in the following video will work for your 2021 but yo can ask your parts department at your favorite Ford dealer.
