Hi, i want to install something and from my understanding in order to switch the view to video input in the back of the unit i need to do something with that reverse detection wire (from my understanding that is the only way), what does it connect to: reverse lights? any other 12v? or just ground? couldn't find anything in manual unless I'm just blind, I'm pretty sure Ive seen a how to install a rear camera but i cant find it any more for some reason.
any help would be greatly appreciated.

splice into the power for your reverse lights, that will send the signal to the camera and the head unit to turn on the reverse image.

Well, I'm not exactly installing a reverse camera so I'm thinking of installing a switch for that wire, so if slice it into 12v it should be working no problem correct?
