I have installed a Rosco Back up Camera to my 1999 Itasca Suncruiser 35C, I have wired it into the old CB radio harness which supplies power when the ignition is turned on and the camera works perfect. My question: Does the Green trigger wire from the camera harness need to be installed? And if so what if any additional power is this going to supply the camera? Plus does anyone know the correct wire from the steering column(Ford Chassis) to splice.
