Blast out a bar of Dixie like in _The Dukes of Hazzard_, or feature any other customizable song, by changing your car horn's sound.
- Step 1: Connect the horns to the compressor using a length of plastic tubing for each. If the tubes from the kit are color coordinated, attach the tubes to the connectors that match in color.
- Step 2: Attach the wires that lead from the switch to the old horn to the bottom of the compressor. For a two-wire system, transfer both wires. For a one-wire system, attach the wire to the positive terminal of the compressor.
- Step 3: Take the car out into the country or to another location where there are no other cars and give the horn a 10-second blow to test out your horn's new pitch.
- FACT: Actress Catherine Bach designed her famous Daisy Dukes cutoff jeans on the show _The Dukes of Hazzard_.
- TIP: Point the open end downward if you are installing a trumpet horn.
- Step 4: Mount the horns under the hood of the car. Drill holes for the bolts. Attach the horns using the bolts, and secure them with a nut.
- TIP: To play multiple sound clips, check out the car horn units that store sounds digitally in the memory of the unit.
- Step 5: Open the hood of the car and find a surface where you can attach the compressor in the engine compartment. Drill a hole in the surface.
- Step 6: Secure the compressor to the surface. Using materials from the kit, thread a bolt through the bolt housing, slide on the rubber gasket, and put the bolt through the drilled hole. Add a lock washer and fasten it with a nut.
- Step 7: Purchase a car horn with your desired sound or pitch.
