I have f920bt with 32pin rca socket, but I don't have rca wires to connect rear view camera.

I want to make just bsl-02 cable connection, only with 2 pins to use camera view:

 

Problem is that I'm not sure which pins are "rear camera input":

 

 

 

When I connect to two pins from right side, my avic freezes on camera view with black screen (only reset helps to back to normal screen), so I guess I connect right pins, but tell me pls which exactly pins are for camera.

 

Next thing is camera settings: what I have to choose in options - battery or ground?
