So if you hear the click then the relay is wired correctly and working. That's takes care of the relay test.
To determine if the camera is actually receiving 12V then you must test the camera power jack (at its cable) itself or the relay terminal 87 for 12V.
The OEM cam emulator is wired/working properly because you do see the the OEM rear camera screen but no video. So your problem is the power to the camera.

I'll try the sleep-then-wake from within the car this afternoon and see if I can get a click/sound. It was not making any audiable noise that I could determine yesterday with going into reverse then neutral then back again. I was guessing the relay only activated when the reverse signal came on... that would explain that aspect then if the relay is hot while the car is on. Thanks for the help.
