Hi Bryn, what do you mean by two tone, like a police siren or is it loud then louder one it kicks off, is the noise not instant? Or do you keep on the original horn aswell? Would I need a relay or just change the connections? Sorry bout the questions!! I have been looking at getting a decent horn and fleabay seems to have plenty stebels!
Cheers....
Stevie, if you piggyback into the wiring feeding the original horn, you are in effect using two horns, the Stebel Magnum and the standard OEM unit at the same time, each has a tone of its own, and you'll hear both at the same time when you operate the horn button.... if you stick with the Magnum ( not the Nautilus) and do this you won't need a relay
