The cametra was installed a little differntly than the apckage described. Instead of screwing it to the license plate I took the third brake light apart and enlarged the hole in the back where the stock light snaps in. I then drilled a 1.25 hole in the red plastic to allow the camera to see out. I installed two new smaller snap in lights to allow the brake light to still function. I fished the wire down and out the factory grommet into the interior. I tapped into the reverse lights (black / ground solid green ) for camera power. When 12V is applied to the camera the front screen recognizes video and turns on. Up high is great as I can see over the boat to back up. Hopefully my wife will also see behind her.
