Horn Installation on a 2001 Audi TT

1. Lift the hood of the Audi and locate the horn. It is circular and held in place by nuts with a wire plugged into it.
2. Unplug the wire from the stock horn to disconnect its power. Use the wrench to loosen and remove each nut mounting the horn to the engine compartment.
3. Remove the stock horn from the Audi.
4. Place the new horn into the compartment to mount it. Place each nut in place and tighten it hard to the right so that the horn is secure. Plug the wire into the new horn.
