Pink wire on this video is the backing up wire for this player but it won’t work unless electricity telling it to switch to backingup view. I connected it the red wire that goes along the video cable to the rear of the car that later connects to the camera and connected that red wire to the car rear backing up light lamp positive cable that’s the cable telling the pink it’s time to which to backup mode. You can also attack your back up camera light to that same car back up lamp wire so it triggers the camera light when you reverse.
