Wolo (HWK-1) Air Horn Wiring Kit with Horn Button Switch

The wires were long enough, two of them were EXACTLY the length needed (*no margin for error) and two needed to be cut. Using this made installing a new air horn quite simple. This simple relay wiring kit makes remotely controlling any number of car electrical systems a breeze (additional circuit to flash your headlights or to install a car starter come readily to mind.) It doesn't come with the relay though - although most air horns you buy will. Make sure your relay fits this plug size or you wasted your time.

This is simply a must have item, no questions asked. I used this to install the Stebel Nautilus air horn & it probably saved me hours. All that you have to do is plug in the relay that comes with the air horn to the wired plug in this kit. It simplified the process like you wouldn’t believe. Even for someone who has command of wiring, it still helps tremendously. Also, the kit includes much needed instructions, something that the Stebel air horn did not have. This kit doesn’t include the 20amp relay but it already comes with the Stebel air horn.

I am not a handy guy, not at all, and I was able to instal a new horn in an old clunker I just use to park at a train station all day. Original horn was shorted out and I was able to hook one up right to the battery thanks to the pre-wired kit. Otherwise I would have paid hundred's to have a shop do it. Only took me about an hour and I can hardly change a light bulb. Hooked it up with a same brand horn and works great. Been a few months now and no problems. I'm grateful that someone made a full kit like this to save me time and money.

I ride a Harley Street Bob and the pipes are pretty loud, but that doesn't keep the ingrates and morons around here from trying to kill me while they chat or text or apply makeup or whatever. The stock horn that Harley puts on these bikes is about as useful as a squeeze bulb horn and almost as loud. My Yorkie belches louder than the stock horn. So I decided to slap one of these on my machine and give it a go. Good God this thing is loud! It's so loud that I like to honk it at people just to watch them jump! Sometimes I honk it just for the heck of it. My advice is to buy the installation kit because it makes everything quick and easy.If you're tired of almost being clipped by four-wheeled idiots, do yourself a favor and buy one of these.

I'm reading the comments and some complain about the switch being sub par. I disagree actually. I think it works quite well. I own a 2000 Crown Vic Police Interceptor and the police department removes all their equipment before they release these cars to the public. And when I purchased my car,the horn circuit was disconnected. I tried to fix the problem and searching the internet for a solution and it seemed that in my particular car,the horn circuit ended up in a wiring harness that was completely cut.So I purchased this kit and hooked up the horn button to my dash just left of the steering wheel. I actually like this switch better than the usual place on the wheel because you really don't have to press hard at all.And the wiring couldn't be easier. The wiring to the switch is actually a negative ground so just hook the switch to any ground. Then I replaced the stock horn to Wolo's Air Horn I found at Harbor Freight that came with a relay then hooking everything else up was easier then checking your oil.I've had this a little while now and it hasn't given me any problems and after months of dealing with no horn I finally have one.This was a great purchase. I can't be more happy.

Makes installation a lot easier. Simplifies everything installing aftermarket airhorns.

I gave this three stars because the kit does work as it's intended to, but it's nothing super special. The air horn Wolo sells says it's compatible with motorcycles. Yes, that is technically true. However, at the very least they should put an asterisk next to that and say, "Only if you purchase the additional wiring kit."Secondly, the kit instructs you to cut the female terminals off your OEM horn wires. I didn't like that idea because that makes swapping out the horn more difficult later. I went to the hardware store and picked up a box of male spade terminals, attached them to the relay wires, and kept the OEM female terminals. It seems silly to instruct you to do that when Wolo could just include two male spade terminals. They already included a couple female terminals in the set. It's not like that raises costs astronomically.Anyway, the kit works as necessary, and the instructions are easy breezy. I'm not an electrician nor a motorcycle technician, but I was able to hook this up. It took me more time to run the wires around moving/heated parts than it did to actually connect everything.

Easy install and complete
