Denali Plug-N-Play Wiring Harness For Dual-Tone Airhorns

I have read the other reviews on this product and I am more confused by their reviews than the actual product.
Super simple installation, 2 wires go to your old horn positive and negative. 1 wire goes to the positive on your battery. 1 wire goes to the positive on the new air horn. 1 wire goes from the negative on the new air horn to any screw/bolt on the frame.
Turn key, press horn button, scare traffic, it's that easy.

I'll admit, the instructions weren't very clear and this was compounded by the fact I really have no electrical knowledge. When I got the harness I felt a bit overwhelmed. With that said, it really is easy. There's a bundle of two wires that you plug into the wires that went to your old speaker wires. You simply unplug the speaker wires from the speakers and plug them into this product. You connect the positive wire to the battery and run it to the Denali. Then you connect the ground from the denali to the bike with the included piece. The only problem I had was thinking I could ground the horn to the bike, which didn't work, but I had no problem once I grounded it to the engine. I spent 3 hours deciding where to mount the horn and fabricating a bracket but only spent 30 minutes installing since I had this harness.

Why is it that companies inaccurately represent products by using the term plug-n-play, when in actuality you need to cut-n-splice....as in the case of this product. When I unplugged the OEM horn on my 2013 1200GSA, I immediately realized the harness isn't even remotely close to the BMW plug, so I called Twisted Throttle (distributes this and the Denali horn). Great, friendly people at Twisted (as here at Revzilla), yet right up front they said oh yeah, you'll need to cut, splice, pick up connectors from a hardware store that were not included, and then try to shoe-horn, er, the horn, into the OEM position (b/c this horn is significantly larger, and there's little room behind the fork tubes). Not to mention the Twisted instructions were approaching the terrible instructions of the German translations that come with Touratech products. All this said, I cannot recommend these products unless they revise their advert to say splicing WILL BE required, and rewrite the instructions (which btw the Twisted rep admitted were incorrect/misleading). Won't know about performance/durability until its been on the bike for a little while, and hoping that BMW sells a make plug with pigtails so I won't have to cut-n-splice in order to plug-n-play. Ugh.

Only problem I had is the relay stayed open the first time I sounded the horn. Removing and reseating the relay fixed everything

This made it easy to install the soundbomb on my Iron 883. It isn't as shown on the pictures - they added more wires. In addition to what is shown here, they added a ground wire from the horn back to the battery. No instructions provided, so red to battery, black to a screw under the seat for ground, two wires for the old horn contacts, two wires for the new horn, and a plug-in for the relay. The wires are so long that I have them coiled 4 times under the seat and will have to go get some connectors to cut them down to length. Works great and took me less than an hour to install the horn.

If you know how to do basic wiring and already have the basic components, this kit is not needed. But for the price and not having to hunt down a relay plug, terminals, fuse and all the wiring of the kit, it makes for a very easy install. Saves time!

This wiring kit made the install so much easier and came with everything needed. I did have to go to Home Depot to buy a longer air hose, but only because I wanted to install the compressor under the seat.

Yeah, could have made a connector but this is a convienent way to get your stebel horn wired up. Leads are plenty long for most writing applications. Save me a bunch of time instead of making up my own harness

If you spent the money on the Sound Bomb why not install it the right way that thing pulls more amps then the stock horn button can handle so you need a relay to protect that button (IT WILL BURN ) plus a fuse to protect everything else. Buying this kit allows you to have a clean professional looking wiring install that you can do yourself.

This made installing the Soundbomb quick and easy. Definitely worth the extra money. Everything wires right up and you're good to go.
