I have my mirror camara with a bridge switch between 2 wires at the mirror harness i can have it on for maybe 10 min after it shuts off and mirror light blinks. It was a piece of cake with the diagram in hand. The issue im having problems with is tapping into those video wires , my head unit only has rca video input should i splice in an rca video wire and use white as main feed??
