Hello, I purchased the auto vox m1 back up camera, it comes with a 4 in screen for viewing the backup camera.
I installed the camera, got everything plugged up and I can’t seem to get signal to turn on the screen.
I spliced into the reverse light, I took the red/black wire from the backup camera and spliced into the black ground wire on my tc2 reverse light.
I spliced the red wire from the backup camera into the black/white wire on my reverse light.

I turned the car in, E brake up and put in reverse. I still have reverse light power but my screen does not power on.

Any ideas?
