After market backup camera help

[Weller]

Hello, I'm usually good with searching for the info I need but I'm having trouble with this. My Dad has a 2015 Sierra 2500 without a backup camera. So, for Fathers Day, I got him a license plate bracket camera and a replacement rear view mirror with screen. Can someone help me figure out which wire is the reverse wire to tap into to activate the screen? I know there's one in the brown plug from the ECM but I've found conflicting info on what color is the wire I need, or is there a better place to tap in?

I appreciate any help!

What do the install instructions that came with the camera kit say? You are most likely best off calliythe company that makes the camera kit you purchased and ask them. They designed the system and should be able to give you a step by step for your install.

Yeah, but they don't have wiring specs for every vehicle. They just told me to plug it into the cigarette lighter. I'll find a thread on radio installs and tap into that reverse wire instead.

If you're looking for what/where the reverse trigger wire is for the truck, you can find the wiring schematics here:

If you put your camera at the rear of the truck you can go to the reverse wire at your trailer hook up
