The CAN BUS has a Green Reverse Output wire that is supposed to be connected to the stereos Reverse Gear wire (trigger wire). My question is; can I connect the camera's positive wire to the CAN BUS reverse wire too? Or do I need to connect it to the reverse lights directly. Seems to me that if the Can Bus has a reverse wire, that I should be able to connect this to the camera as well rather than running a seperate connect ot the actual reverse lights. Unless the Can Bus wire does not supply enough amperage or something.
