Safety Vision Observer VCR based system in a locking steel box, mounted under the first seat behind the driver. These are the same seat clamps used by the manufacturer to attach the seats, so they are available from the manufacturer. Notice the back of the box is close to the wall where the wire will not be visible to children. Each clamp has 1 large diameter self tapping screw and 2 small diameter self tapping screws angled inversely so they cannot wiggle free.
