Lil Red,
I've got the part number at the house and will post it tonight. I'll also find the camera I used from EBay. Not all will fit the hole as they come in different diameters and different lengths. I finally found one that was pretty close. I just had to file the hole a minimal bit to get it to slide in.
Chad,
Just as Sal said, it is just to help you be able to see the area in close proximity behind your vehicle. I basically just use mine for hooking up trailers so I don't go too far and crush a tag. When I put my ST in reverse, the camera comes on the screen of my Alpine, so I can see right behind me.
Here is a pic of the handle with the camera at bascially a 45 degree pointing down:

Look on the left of the handle. The key is on the right.
