Motorcycle: 2005 YZF600RTS The horn and it's wiring is pretty straight forward. Follow the instructions to connect the included relay to the existing horn wiring and you will be good to go. The most difficult part is FINDING A PLACE TO MOUNT THE HORN. I started at 8am this morning and just finished at 6pm. Taking several beer breaks along the way. The good thing about this horn is that it can be separated in to 2 pieces; the air compressor and the horn section. This is the route I took as there was not enough room to mount the whole horn behind the fairing without major modification. (Or I was just too lazy to go that route) I mounted the air compressor in the compartment under the seat and zip tied it in. Don't mind the nest of wires. I can make things work but can't make them neat. The clear tubing you see is a 5/8 diameter clear air tube I got from Home Depot, (10 feet worth). It runs from the compressors outlet, down the inside the fairing of the bike, to the horn. The hose didn't exactly fit into the inlet on the horn so I had to slice the tube and fold it over to fit. A few drops of superglue or silicon sealant wouldn't hurt to make sure it stays. BTW, that little hole you see top center on the compressor is the air intake. It is supposed to be mounted facing the rear or a tube inserted to face the rear to keep debris from entering the compressor. Since it is under my seat, there's less worry of that actually happening. Just above the stock horn is a plastic deflector. Being that once I separated the horn from the compressor, there was no actual mounting point for it. So I zipped tied it to the deflector and screwed the deflector back into place. If I ever get the front clip off, I will add a few more zip ties for good measure. It hides out of the way pretty neatly. The last part was the relay. Follow the directions to hook up the stock horn wiring to the relay and then to the horn, (air compressor has the actual connections). I recommend you get extra lengths of 18 guage PRIMARY wire for the install, (depending on where you decide to install the horn). Use everything that comes with the kit. This horn will not work with the stock wiring. Well, it may work for one horn button push and then your horn button will probably short out or fry itself. Does it work? HELL YES! Scared the hell out of my pocket dogs. The sound is instant with the push of the button and it's LOUD. No compressor lag whatsoever. Puts the stock horn to shame. I would have a test video but it's late and I don't want to disturb my neighbors. If you have any questions, feel free to ask.
