Abstract: Wiring for a car reversing camera system in which a single, long multicore cable carries power and signal wires from a rearward camera position to a forward monitor position. The multicore cable feature at least one narrow width connector that can pass through apertures in a vehicle chassis without drilling holes in the chassis. Power is provided to the long multicore cable from a junction unit that steals power from a car's electrical system that is actuated upon reversing.
