This is what I thought that your camera will look like...

Have you tried to fit it into the license plate light opening yet? If it fits nice and snug, please post pictures of how you did it - otherwise, you might be in for some cutting of the light circuit board, that is under the license plate light cover lens...

Also, when you have the camera's light connected for the license plate illumination, you might (or might not!!) have to program the Cold Monitoring of the lilght circuit to be turned off. Well, we'll cross that bridge once you are there...
