Interior overhead lighting wires

[rrt5th]

I recently bought a 2019 Ram Big Horn Crew Cab 4x4 after selling my 2013 Ram 1500. I had a Valentine 1 radar detector mounted up by the sun visor that was spliced into the power wire for the sliding rear glass window switch in the 2013 Ram. For this truck, I am trying to tap into the power wire for the interior overhead lights to power the radar detector. I have searched this forum as well as the internet and cannot figure out which wire is the hot wire. Maybe the info is out there but I cant read wiring diagrams either. I was curious if anyone here knows which is which. I've posted a picture for reference. Any help is appreciated!

Unless you can find a schematic, I think you'll need a multimeter to figure it out

As long as you got it, great. For others, post #57 in this thread may help to wire into active windshield wipers:
