The Stebel is especially simple to install if you order one from
Bikerhiway.com. Click on that link and you'll see another link for installastion instructions in a PDF file(it's just below the play button to hear what the horn sounds like). They also include everything you need to install it except for the tools.
The only thing you have to figure out is where to mount everything. I put mine under the seat since my bike has been Freakenized. The relay also sits under there.
