HOW TO: Add Digital Rearview Mirror

[mlcjohnson16]

Here is what I have so far:
I'm working on is adding the Digital Rear View Mirror with 2 inputs and Forward Collision Warning / Adaptive Cruise Control to the Ram 1500 (my current regular mirror has both of those.

I also added the Backup Camera Kit (Which I think is the camera kit for on the trailer itself, but maybe it is the wiring for under the truck. Getting necessary components to go from the DRVM to the bumper of the truck is where I'm stuck. I added a trailer tow connector and a dual camera housing in this parts list, but wonder if I'm missing something.

Do you know if the backup camera kit below is all the wiring for on the trailer or the underside of the truck. If it is for the trailer, do I simply need another longer FAKRA cable to snake through (or possible multiple) to get from the DRVM to the Bumper where I'll install the tow port?

My Ram VIN is 1C6SRFJM7NN353467
The parts I have in my cart are (hyperlinks included):

Inside Rear View Mirror: 68519222AA
Center high Mounted Stop Lamp: 68551077AB
Back Up Camera Kit: 68527599AA
Trailer Tow Connector: 68532403AA
Trailer Tow Connector: 68532402AA

In the process of installing the mirror, 2022 RAM 2500, CHMSL and cable already fitted some time ago.
In the process of checking that the mirror covers from the original mirror will fit, found major differences.
Are there specific covers we need to use on a 2500 when fitting the DRVM?
