Great part
Wiring kit was a class piece of equipment. Only recommend having a lip on the plastic box with a couple holes in it to fasten to underside with screws. The double stick tape was easy and even cleaned a spot with alcohol for good adhesion but after one trip down the road it fell off and was hanging down. Thank goodness for long zip ties in my tool box.
