I want to install a universal rearview camera in my VW T5.2. How do I connect the camera correctly?
In the picture, you can see 1 for ground and 2 for 12V. Then there's B for reverse gear detection.
I have a Canbus Raise G-RZ-VW58. I have a brown cable on the Dudu7 wiring harness that says "back." Do I connect it as shown in the picture, or the cable with the B? How does the radio detect that I'm reversing and automatically switch to the camera so I get a picture?

I have this cable on dudu7
