In a matter of seconds, the Flash will disable the double horn honk reminder on your vehicle. Want to re-enable it? Simply plug the programmer back in!

    Perfect solution. Easy to use - worked first time. Not getting yelled at by people who thought I was blowing my horn at them when I got out of the truck and closed the door. Stupid idea by Ford. Easy fix by 4DTech.

    Thank you for offering a solution to the really annoying double horn honk when step out of the car when it's running. Very annoying, and flat pissed my neighbors off when I go to work at 2 AM.
