Dash Cam in ‘21G550
Correct me if I'm wrong. Once the back camera wire is run through that section circled in red, is the rest of the wire run to the front passenger footwell? If not please explain.
What is the most important parts of the installation I need to be sure they do correctly? The company has been around for a long time and have good reviews. But this is a 2022 and things change. Thanks in advance.

There is not much too the installation that makes it special. The rear camera just plugs into the front camera and the rubber grommet on the tailgate is a good access point to insert the wire through.
in the passenger footwell I have a backup battery so it can record 24/7 and the power for the cameras in tapped into a power source there. However, if I remember correctly the rear camera just connects to the front camera. Then the cameras receive power from 1 cable that goes from your power source to the front camera.
If they are experienced they will have no issue.
I did have to bring mine back to the shop as it wasn’t running off of the backup battery when the car was off. So they had to add in a resistor or something. It sounded like something they have to do often to various cars.
You will be fine.
