I already had rough-installed it before going to Daytona '13, but took the time to do it better today. Here are some pics. First shot is original 'proof-of-concept' fit on the left side engine V, but this blocked the thumbscrew for the carb idle adjustment. Switched it to the right, no mods needed to the bracket, it's "bi-!" I ran some jumpers from the stock horn wires back to the underseat area, I think I had 14 ga wire on-hand, you don't need it that-heavy. because I have Gannon's excellent COP's, I have extra room where my coils on-top of the battery used-to sit. I installed the relay onto one of the screws for them, the left front screw. This allowed me to use the heavy-gauge 30 amp sealed fuse in the Stebel horn wire kit I bought yesterday at Competition Cycle Center, Dania Beach FL 33004 for <$9. I ran the Stebel leads to the airhorn which I mounted on the right side of the engine between the V. I made a bracket out of some 1-3/4" aluminum angle I had lying-around. It looked pretty-ugly in its natural color, so I spray-painted it the same color as my bike. Better, but still way-overkill for what it had to do. So, I used my drillpress & some hole saws to Swiss-cheese the bracket. Very steampunk, now, I think!:biglaugh:. Then I repainted it black. I used fully-insulated M/F spade terminals instead of the ones that came in the Stebel wire kit. Better protection against accidental grounding. be-sure to turn-up the volume when you play the video. If you hear me breathing heavily, it's because 1) my VBoost works perfectly, and I'm excited about it 2) I have a cold, sorry :rofl_200: So, that's it for my WOLO Bad Boy which is available at HFT or Pep Boys. Using the relay made a big difference! My l'il buddy was very impressed by the dB output! "meep-meep!"
