Wiring Colors

I'm going to attempt to hard wire my Garmin backup camera to my 2014 A122BH, and it would be great if I could easily tap into the wires running to the back.

Here's a photo of the wires just under the bumper that I assume lead up to my rear lights:



Ideally I'd have it on constant 12V, so I could see behind me, but if none of those are constant, I'd at least like it on a line that's on when the headlights are on.

According to this diagram from eTrailer, red might be the one: Trailer Wiring Diagrams | etrailer.com

Thanks!

Brown....believe the red is for charging rv batt. while traveling. The brown is also active w/park lights

I actually ended up poking around a bit more and realized how easy it is to just run a dedicated line from the battery. That way I now have a switch too, so it's not always on when the camper is just sitting there.

The holes that the rest of the wires hang in under the camper are actually pretty easy to reach and run more wire through. The ground is just on that frame ground that's already next to the back bumper.
