Can you set up a reverse camera to an aftermarket head unit?
It’s possible on some makes and models to fit an aftermarket head unit that can be integrated with the factory reversing camera. We recently installed a Pioneer visual head unit into a Toyota Corolla, and configured the factory reversing camera to work with the Pioneer gear.
What are the 2 red wires for on a aftermarket backup camera?
The red wire passes the reverse signal up to the front of the car. The camera end has a red and black wire which the red wire gets connected to the reverse light and the black gets connected to ground.
