It was 50 degrees and sunny today, here in Indianapolis. I went for a 75 mile ride and ended up buying a Stebel Air Horn at Cycle Outfitters. Came home and on Amizon.com I ordered a "Universal Plug-n-Play Wiring Harness for Motorcycle Air Horns" ($25.90 delivered) to make the install easy peasy. Once it gets here that'll be my next project.
