parking sensor kits,The wiring is simple, finding the access hole took some time -there is one on the driver side and you will need to remove the back panel (in the trunk) to get at it, but it's only held on by two screws and some plastic tags.Once the wires are through you connect to the backup light - easy too - they are up under the trunk hood - red wire positive - white wire negative. The kit includes a small indicator light which also sounds the beeper. I installed it inside one of the air slots (vent for the battery pack) and routed the wire under the rear deck panel and into the trunk. This way, I can see it in my rear view mirror. So far, so good, very sensitive to movement (i.e., a child, or something). The only drawback was the price - 300 bucks. Hopefully it was worth it, will let you know.
