Rear View Camera Install ???
Where do you tap the black rca with the red wire for the constant/aac 12 v power supply in the rear of the car? It also has a black wire for ground. It is my understanding that this is the constant power for the camera when the car is on so you can just turn the camera on anytime from the head unit.
I connected the red power supply from the yellow rca to the purple/white on the head unit and then to the reverse lights at the rear of the car. It is my understanding, this is the switch when you put the car in reverse.
