mswscco,I just bought a backup camera and monitor and the dealer did it in less than an hour so i guess it is pre-wired.I also talk to one of the tech and the camera is pre-wired located behind the rear door panel i beleive if you look at your rear panel there is a small cut square there.here is a few pic..camera is located in between the two license plate light.
Monitor is also pre-wired and place in the 1st sunglass cabin.They changed the trim so you can fold or flip down your monitor.
