Description:The available space under the body work of a ST1100 ABS makes the installation of the
Nautilus Compact Stebel horn a real challenge. This install takes you step by step on
how to separate the compressor from the trumpet for a more flexible installation. It also
allows you to place the trumpet at the front of the bike as it should be and the
compressor in a nice dry spot so water has much less chance of getting inside it and
causing damage. First, here are pictures of most of the supplies that you will need for
this project â€"
Parts:One Stebel Nautilus Compact Horn(http://inlinethumb22.webshots.com/43221/2234895120053425152S425x425Q85.jpg) (http://rides.webshots.com/photo/2234895120053425152XsZKcC)

Various Wire and Terminals
(described below)(http://inlinethumb03.webshots.com/45250/2954956320053425152S425x425Q85.jpg) (http://rides.webshots.com/photo/2954956320053425152xcBrPa)
The wires and terminals you will need are (lengths are approximate because it depends
on where you put the electrical components) :
Three feet of 18 gauge wire (red), eight feet of 12 gauge wire (red), three feet of 12
gauge wire(black), four right angle terminals (for relay), 3 ‘eye’ terminals (1 for ground
for horn, 1 for ground for relay, 1 for battery or fuse block connection), 3 female spade
terminals (1 for hot to compressor, 1 for ground to compressor, 1 for terminal on stock
horn), and 1 male spade terminal (for pigtail to original horn connector).
Special tools needed are a drill bit that makes a big enough hole that you can get a
12mm socket through, a vise and really good hammer for making the compressor
mounting bracket.
