For anyone interested, here are the pin and wire color assignments (on the camera harness) for the 2009 OEM camera. I believe the pin locations are the same as the 2008 camera.
I ordered two OEM cameras off ebay. $70 each including the Ford emblems and bezels. Bench tested them today and they work great. Better picture quality than just about any aftermarket camera I've seen and the OEM camera has the guide lines which I think is helpful for those that tow trailers. I think the total for the parts from the dealer is more than $200-$300 so I'm happy.
Now if I could just find such a deal for the OEM LCD monitor rear view mirror.
