Hi all, I am just about to add a reversing camera to my Leon. I have the camera & a rearvirew monitor on the way, wifi transceivers are here (so I don't have to run a wire all the way through the car). The question is: Is it possible to wire 2 camera's in, I want to add one to the rear of my caravan, so that when it is plugged in via the 12S plug I can use the reverse line to power the camera, switching out the one on the back of the car. I was thinking about a relay, wired to a spare part of the 12S plug to ground (if there is one) so that the relay is powered by the reversing light signal & grounded by the 12S plug. Then the NC would be to the internal camera and the NO to the feed from the caravan one, the com going to the wifi repeater. Or even simpler a switch I throw to select which I want powered. What do you guys think about this?
