I installed this unit on my motorhome. Took only about 20 minutes to install . Only needed to drill 2 small holes using one of the small bolts to connect the ground wire and splice connector to the power side wire of the back-up lights. It has been on a few months and still works flawlessly after driving many miles in heavy rain. I would recommend this Back-up alarm!

I've used/installed several back up alarms. This unit is considerably louder than the previous units I've installed. I put unit in my car yesterday and will put another one in wife's car today. Great device to help avoid injuries and alert folks that car is backing.
