I’ll take stab at this. For 2022, it seems that the trailer hitch lamp is standard on all trucks? I can’t find any sales info that clearly states this, but, all the 2019-2021 tailgate handles are the same part numbers for their colors and cameras, and 2022 has a completely different set of part numbers. Here’s the list of 2022 handle part numbers below, and these are the sales code meanings:
MNA= Black textured
MNK= Body color
MNE= Body color with chrome
XAC= regular backup camera
XAK= surround view backup camera
XJJ= locking handles (standard)
Positions 7 & 8 in the part number define the color of the handle. Example: PAU is the paint code for granite crystal metallic. Drop the “P” in all the part numbers, and 7KJ43LAUAA is a granite crystal handle.

So, according to that list, the tailgate handle part number that you and g00fy have is for a black textured handle that accepts the hitch lamp and REGULAR backup camera. A black textured handle doesn’t exist that accepts the surround view backup camera.
For the tailgate handle jumper wiring, same as above- new set of part numbers for 2022 (*presumably* containing the lamp connector now).
Harness for regular backup camera equipped- 68521315AA
Harness for surround view backup camera equipped- 68521314AA
I’ll keep looking, but so far, I’m not seeing the part number for the lamp itself.
