depends on so many things
the Stebel (Nautilus) horn must be fitted vertically
you can separate the air compressor from the horn element
there is a relay supplied with the horn, but its seems to have a dodgy reputation.
I think the horn shouldn't be forward facing if there is a risk of water being driven into the horn through the air outlets at the base of the horn
I mounted my horn behind the left hand takn panel, ground off the bracket, the with judicious use of cable ties, rubber panels glued to the tank..
you can fix your own horn if you want. the only gotcha is the OEM horn is 'hot' ie the circuit is always powered and the horn switch grounds the circuit to make the horn sound. relays are easy enough to fit, assuming you have a crimp tool, some crimps, some wire or suitable size.
