I have my rear cam setup using the Kenwood 9703s on my 2006 Z06, but confused on the red RCA plug and how to get power to the cam. I have the Yellow RCA connected to the cam and then into the radio, but the Red RCA plug next to the back of the car, how do I wire that in? Do I look for a power and ground back by the rear lights?

Tapping into the reverse light power wire? Or run a power wire that is switched by the ignition if you want to view to the cam while driving. I haven't hooked up a cam before, fair warning
