Aftermarket Airhorn

I believe I may have found my answer looking through the forums without quite finding the subject. I realize that I can not simply add the product to the original wiring without causing an overload blowing the fuse and taking away almost everything else.

Can someone confirm that putting the horn on it's own circuit may be the only/best solution?

Well when I hooked up my driving lights, they just plugged into the existing wire. I preferred to run my own wires for them and a relay. Does the label list the current draw (amperage) for the horn? Can you just use the existing horn wiring or use it to trip a relay with dedicated battery voltage?

Yeah, good question. Sugar Bear was pretty naive on his too. I just thought plug in and go, wrong answer, I still ain't got mine hooked up yet. Nice to hear some thoughts on that. I did hook it up (remote) to see how it sounded- WOW- downtown Burbank!!! Ride Safe.
SugarBear What make and model is your horn?
SugarBear What make and model is your horn? I just looked up the Stebel Nautilas and it pulls 18A at 12v. This link may help with the wiring.

Fulltilt1,
I have a WOLO Bad Boy, model 519. Thanks!
Relay and fuse

I believe since the air horn pulls so much current, you need to go direct to the battery add an in-line fuse and a relay. The relay is picked by your present horn button. The power to the new horn is supplied though the relay. One of those flat chasse mount relays for fog lights would work.

That's what I did when I put my driving lights on.
Thanks Dave, Sugar Bear will be the first to admit he is a total dumbass when it comes to electrical stuff, can hook up red to red, white to white ect, sad part is my kid brother has been an electrican for 40 years, but the pride thing can't let him think I don't know:eek: Thanks guys for your input! Ride Safe.................
Lookin at those diagrams I guess the upper right would be the one to use, with one exception. Where it shows the wire going to the switch don't worry about making that connection to the fuse/battery. Your connection to the switch from the battery is already made. The wire that is on your stock horn will connect to 86 and connect a ground to 85. 30 is always from the battery and 87 always goes to the load (Horn). If the horn is metal and you mount it to metal you may not need to run a ground, but i would plan on one anyway. I'd plan on using 14 or 12ga stranded wire. You can get a fog light relay 30A at autozone or pepboys. Hope this helps.

PS Looks like Stebel might be the manufacturer of your BOLO horn. They look an awful lot alike.

Fulltilt1,Dave,
Thanks a ton guys, Sugar Bear does VERY much appreciate your reserch you have helped me a bunch, will go with what you guys say.:D
Your Welcome Sugar. Fulltilt is out headin home from work!
Thanks Fulltilt and Sugar Bear for the responses. It looks like I have just a little bit of work to do. :( I did get the Nautilus and did mount it on the OEM bracket with the OEM wiring. :eek: That will be changed soon I hope.:)
I have one of these coming:

Stebel Nautilus, Compact Motorcycle Air Horn
[Finish:Chrome]
[accessories:Wiring Harness]

This does come with a relay and is 130db! I had one on my goldwing and it saved me a few times. People know you're there. I bet that the horn is louder than the pipes.

Mine should be here in a day or two.
