Question and help needed about the Stebel Air Horn

[Guest scooter38]

OK guys need some help here, I got my Stebel Air Horn during the week from http://www.twistedthrottle.com and I got the plug and play wiring kit to go with it figuring to make it eaiser to install. Well the connections they have are different from what I have seen here, which are, connect the black wire from the relay post 85 to the ground, so I hooked up to the battery negative. Run the red wire from the relay post 30 with the built in 30amp fuse to the positive battery terminal. Run the yellow wire, from post 87 and hook up to the positive of the air horn. Next connect the ground wire to the negative side of the horn and ground it at the mounting bolt. Install the fuse next. Next run the blue wire from post 86 to the existing horn hot wire. Ok so here's the deal got it all done tried the pink wire first and the horn was quiet and was on at time of turning key on. So tried the brown wire, and same thing. SO then tried both together and got the sound I was looking for from the horn but it still, as soon as I turned the key on the horn sounded. I'm curious as to what will happen if I take the wire on post 85 and hook that up to the pink wire and just hook the brown one up to the post at 86. Any ideas or knowledge of what will make this work with the wiring kit, or am I better off just wiring it the way Larry has it? I do like the whole connection thing they include nice wire harness to plug right into the relay, makes for a clean look and easy to unplug. Anyway, any help would be appeciated, Scott.

Guys, I'm having the some problem as the above post...thought I would save time and be easier to use the "plug and play" when hooked up like it says, I get a constant honk when I turn on the ignition.

Any advise would be appreciated!

The reason you guys are having trouble is in a car the horn is grounded (-) and the (+) is turned on and off by the horn button.

 

On a motorcycle power (+) is always applied to the horn and the ground (-) is switched.

 

Your directions should be changed to "connect a hot lead (+) to relay post 86 and hook the wire from the horn switch to relay post 85" Ideally the hot lead is turned on by the ignition switch.

 

Or, you can just plug the existing horn wires to relay posts 85 and 86 like the attached diagram.

Thanks MiCarl! The diagram did the trick!!! I guess some of us are just more visual...:clap2:

Let me ask the stupid question. I am planning to get a Stabel horn.

Is the "plug-and-play" wiring required? Relay required?

Why can you not just wire the Stabel with the existing horn wires? I assume it has to do with an increase in amp draw.

Relay is required, yes the increased amp draw, is why the relay is used.

The plug and play is a waste of money! You need some wire, connectors, inline fuse, and a relay...it really is that simple.

My Stebel came with most of what I needed, except the bracket to put it where I wanted it. I know you can easily fabricate one to replace the stock one near the passengers floorboard, right side, but I bought the Carbon_One bracket, sold in the classifieds.

 

The horn comes with the relay. BUT, I wired it straight from the battery because it wants a lot of current to get full loudness. I ran a fused 10 gauge wire to the relay, then 12 gauge wires from the relays to the horn, per the instructions (I think the bracket came with better instructions). I also bought special right angle connectors for under the horn. In all, it was easy.

Here's the Carbon_One bracket.

Here's under the seat, where I put the relay. Note that I eventually installed an auxiliary fuse box, and cleaned up the wires.

Installed. Note the right-angle connector on the bottom. Also, I took off the chrome disk from the back side of the horn, and glued it to the top of the horn. But that came off too easily. I think I need to epoxy it or something.
