Reverse camera install

Hi All,

I just ordered a reverse camera on ebay.

the device has 4 wires

*1* video +
*2* video ground
*3* power supply +
*4* ground

Here is the TV tuner pinout diagram


I can suppose that

*1* goes on WHITE/13
*2* goes on WHITE/14
*3* goes on +12V of reverse light
*4* goes on ground of reverse light / or any other ground.

The question is : Must I use the connector BLUE/17 to activate the reverse camera video automatically when i engage the reverse gear ? if YES, am i right by supposing that i need to purchase a 12V relay to switch this pin17 to GROUND (as described on diagram) ?

Or the fact that the camera is powered only when i engage reverse (through the reverse light) is enough to active automatically the reverse camera video ?

Thanks in advance for your support
regards
patrick
