Mike,
Thanks for the pictures! I know mine does not have a relay in the same location. I'll probe it for power. The power location makes it easy to add a camera. A reverse camera will go in place of a license plate light.

oldskewel,,
Do you remember the wire color? Do you have any pictures? With the info posted above, I can install both front and rear cameras in one afternoon.
