This is an aftermarket tailgate and camera, not OEM.For you, going from no camera to having one is more.

Before purchasing check the back of your Monitor/Screen that you have a Yellow RCA input for easy installation.

If you don't have a hole at the bottom of the tailgate for the wires to come out, you can drill a 7/8" hole and one on the bed lip to pass the wires along the frame.

For the power supply, you can connect it to any 12V power source. For example, if you wanted the camera to always be on, you can connect it to a 12v source that is on all the time, or if you only want it when you reverse you can connect it to the reverse taillights. Includes video and power extension cable, 8 Meters.
