Which wire is positive?
Trying to mount a backup camera onto the back of my Vintage Cruiser. Removed the rubber flap from the camera mounting bracket and exposed two white wires crimped to the black camera power plug wire, and one red wire crimped to the red camera power plug wire.
The power plug will not work with the camera I have, so I cut the crimps off and removed the camera plug.
Using a three-port wago wire connector, I connected the two white wires to the black (-) wire of the camera. I connected the red camera wire (+) to the red wire from the camper.
Turned everything on and have no signal.
OK, now to sound stupid: I assume the long white light above the camera light is a backup light, but it doesn't light up when I put the TV in reverse. It does, however, light up red when I turn the headlights on.
So I'm stumped.
Suggestions?
