Lets you use trailer brakes on any vehicle without a trailer brake controller as long as it has a 7 pin connection.

Trailer settings changed with app but app is not needed for it to work.

Brand new installed on truck 1 time for a few minutes when I learned it wouldn't work for my truck.

Found out it won't work with my truck due to my truck being wired wrong.

Getting rid of the truck so I don't need this, store I bought it from will not take it back unless it's not working.

Paid over $350 for it just trying to recoup some of my loss.
