Used on my 14 Dodge Ram an so far it works great. Just what I needed.

This product works really well and super easy installation if you are electrically/ mechanically inclined. I used my fish tape to pull all wires and an easy add a fuse to trailer backup fuse in engine compartment. Works extremely well.
