Factory Rear Cam w/ Aftermarket radio

I bought the factory rear camera to add to my Kenwood 6019. My 07 LT1 wasn't prewired for the camera but we needed to manually tap into the camera anyways. We couldn't get the camera to work. Do you think the camera actually needs to be programmed itself? You wouldn't happen to know the wire diagram for the camera?

Any help from Dave or anyone else would be appreciated.

Thanks Dave!
