OEM front camera wiring diagram

I'm looking for the OEM front camera switch wiring schematic for a 2020 Pro. I want to tie the switch into the second switch on the MESO stealth knob. There are four wires going to the switch, and I'm guessing two are for the switch backlighting. Anyone have the schematic, or can point me to it? Even better if someone has done this mod already. Search is failing me.

 

Have you had any luck tracking this info down? I just got a 2020 a few weeks ago and had the same plan for my MESO stealth knob secondary button.

 

Any luck on this? Would like to do the same! Thanks!

 

Wow missed the last couple of posts. All the details are in another thread. To save you from going through the entire thing, this links to the schematic and keep reading for details:

Spoiler alert: It works great, and I use it almost every time I drive the truck.
