Tow Mode Camera (Wired) $450 option- this is the digital camera for the digital rear view mirror that you would attach to the back of a trailer, and plug into the bumper. It’s image will display in the rear view mirror only, and will be selectable between that camera, and the rear view mirror camera that is in the CHMSL.
Mopar Trailer Camera Wiring w/No Camera $515 option- this is the truck wiring prep for the aux trailer cameras 1&2 that have been offered for a few years now, and it would include the 12/7 way trailer connector. This option only preps the truck wiring itself to accept the trailer wiring kit, and has the feature for the aux cameras enabled in the radio. The camera kit with wiring that plugs into the 12 way connector is available separately.
To avoid derailing any further, if you start a thread specific to the differences between all these camera systems on the 2022s, and tag me in it, I can explain in more detail how each of them gets hooked up to the truck.
