I recently purchased a Dukes of Hazard Dixie horn from the eBay store 'OEMTOYOU' for $50, including shipping and like it a lot. It came with 5 horns, a compressor, tubing, a 4 prong relay, and mounting hardware. I followed the instructions, trying to connect wires through the relay and, as soon as I put the positive wire on the battery, the horn just continuously went off. After about 30 mins of cussing and failed attempts, I just cut the wire to the stock horn and connected it to the positive connection of the compressor and ran a ground wire from the negative connection of the compressor to the engine and, viola, it worked perfectly! Although, I do have to hold the horn (steering wheel) down to play the entire tune, it beats the hell out of dealing with countless amounts of wires, a relay, and connecting to the battery!
