Similar issue on 2012 Coupe

I’ve tied in using the black w/purple but looks like it’s a constant?! I’m wiring in a dash cam with reverse cam. Does anyone know which wire I can use that’s powered only in reverse? I can use rear lights wiring harness or can tie into either bundle running inside the cab along the rear panel.
