Camera-source.com sells a kit that is a direct plug in. It includes the camera, cable and a mount for the camera. It's pretty expensive though. You could buy the camera direct from Ford and the cable is available on ebay.
Cable is a Fakra brown F to F.
I bought the kit and mounted it to the camper and it works well but if doing it again I'd probably buy the parts myself. I actually ended up using the ebay cable because the one that came in the kit was way too long.
PS: make sure you get the 360 kit, they sell a few versions.
