Compact Italian Air Horn

[speedevil]

The kit (stebel atleast) comes with a relay. You should technically run a fuse too. I never did, and i've had a few instances where my finger was on the horn for over 40 seconds at a time. Supposely without the relay, the horn is really week.

You're correct and since it is carrying a fair amount of current, I think it must be fused and run directly from the battery to the relay.  I reviewed the wiring diagram and I don't see a relay in the horn circuit.  As long as the horn switch is used to close a relay, the bike's wiring is safe.  Running the horn directly from the existing wiring is a bad idea, and it will be weak-sounding as well.

I believe the Stebel install instructions make this clear - I was just making the point again so that someone doesn't just plug in a stebel and burn up the switch and/or wires.

Actually, most people that don't install the relay find that the pump motor is what burns up.  Without the proper current, it dies prematurely.  I've seen the same story many times from many people (on the net).

so is it best to get it with the "deluxe wiring kit" as available on this site??  http://www.bikerhiway.com/wiring-kit-for-stebel-nautilus-compact-motorcycle-air-horn-p-281.html

I would not buy the "deluxe wiring kit" myself.  To me, what they are actually selling is "some way-overpriced stuff that you might need to install this but you will still have to go to the hardware store at least once before you are finished" parts package.

Most folks that do any wiring on bikes or cars will have what is needed in the parts bin in the garage.  The relay is included with the horn, so as long as you have some female 1/4 spade terminals for the relay you're good to go - the rest is just solder and shrinkwrap.

Any pics of it installed?

I forgot (sorry) the owner's name.  I took this picture of the attached airhorn on his S4RS and I'm highly considering doing the same on my S4RS.  the setup looks very OEM and it doesn't stick out like a sore thumb, IMO  .  Also, there's no air flow blocking the radiators.  He used the same OEM horn bolt hole locations.  Oh and also, it's directly wired to OEM wiring without the relay and it's still loud.

Exactly. The relay was included with my Wolo horn and I had wiring and female spades in the garage already...
