works well enough I guess. When I wired the horn to work with my factory horn it fried my circuit board. NOT COOL. I have not repaired my board, but have been told it will be at least $200 to fix. The horn does work but after it fried my board the compresor shorted out and I had to have amazon send me a new one. Way more trouble than it was worth. Wish I would have NEVER bought this item.
