Install of Stebel horn Help Please

Recommended Posts

Just want to make sure that I am doing this right.

I am installing a Stebel and was told that the switch on my 04 K1200GT is already switched and I do not need to install a relay.

 

Is this Correct?

 

Any help would be great

The only way to tell for sure is to look at a wiring schematic for that particular bike. If it had dual horns from the factory, it is possible that it has a relay already. But the question is- is the wiring on the bike a proper size for the load to get the maximum output from the horn? I wired mine with 14 ga. wire to be sure, and used the relay.

As noted above, generally the air horn needs/draws a lot more current than the stock horns. As a result, I have installed 4 of these, and in every case I used 14 gauge wire to feed the air horn from my auxillary fuse panel, and then used the OEM horn wires to feed a new relay as part of the new wiring harness

 

see attached schematic

You should definitely use a relay if you want to get the maximum out of the horns. The horns draw a lot of current and work best wired directly to the battery. I would use a relay even if your bike came with one from the factory.I dont' believe that your bike has a Canbus electrical system. but if it does then a relay is mandatory. The other benefit is that you can use the stock horn in addition to the Stebel horn.

I installed the Stebel on my R1150 w/o the relay, as one is already inline. I did see the draw go up from 4 to 18 amps. Just used a bigger fuse, and no problems at all. thumbsup.gif

One of the other advantages of adding your own relay is that is also gives you the opportunity to upgrade the wiring as mentioned above. Smaller wiring will result in a voltage drop to the horn. It you want to max the output (which I assume is why you bought that Stebel), then add your own relay and beef up the wiring.

I just ordered this horn from pirates. I have no idea how I'll get it installed. Attached schematic? huh? Anyone in Texas wana help me get it wired up to my GT? I'm so clueless about electronic stuff. All else fails I'll prob have to take it to a dealer but I'm not confident 1/2 of them will know what to do.

 

Any advice, suggestions appreciated. thanks!

i bought my stebel from bikerhiway, it arrived promptly was priced right. it came with a wiring harness and all connectors, and inline fuse and a relay, and excellent clear installation diagrams and instructions. now if it only sounded like a truck horn and not a alfa romeo horn...
