Does work with OEM back up cam

[Jpage978]

Installed Atoto S8 few weeks back thinking had to replace oem back up camera, searched online for weeks trying to find out how to tap into camera wire, 2 aftermarket cameras later, the harness I bought had the trigger wire for stock back up camera the whole time, now my truck has 3 cameras I can switch through

I bought the same radio what did you do to get the factory camera to work?

The stock back up cam has yellow rca input, and I believe there is a reverse trigger wire coming from truck that can be connected to the aftermarket wiring harness, I have axxess axvi-6523 harness
