The ISO system deployed by the universal fit Android headunits gives a high degree of flexibility and reduces the need to cut and join wires. This is true from the main speaker and power connections, so these can be plug and play.
But one of the main selling points for an Android headunit is the reversing camera feature. A rear mounted camera and feed the video signal to the android headunit to help when backing up a vehicle.
Backup camera wiring uses the PINK 'REV' wire on the universal fitting android headunits. There are two very similar but slightly different wiring schemes for the reversing camera and the REV Wire on an android headunit. The first system (A) picks up the power for both the signal and the camera at the point of the reversing light cluster or very close to the lamp in the rear cluster loom. The second system (B) is used when it is more convenient to pick up the reversing signal near the front of the car, like the cabin fuse box.
