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.

Used it to install Wolo Bad Boy horn on my Vulcan 500 couple of days ago. Made the process so much easier. Installation instructions are very clear and easy to follow. The only minor issue I had was that one of the wires that you to attach to the horn's positive terminal is somewhat short if you installing it in the same location as the old one and routing wires under gas tank with relay placed under the seat. I also had to turn horn 90 degrees with connection terminals facing sideways instead of down to accommodate the shortage. Other wires had plenty of length and made me wonder why couldn't it all be the same length. Nevertheless so far so good. Will see how it all works out.

The product works well and the directions are clear. Some of the wire lengths are odd and i ended up having way too much of some of the wire, and not enough of others. There is a picture of a relay on the front of the package, but there is no relay included. Not really a big deal, that information is included in the product description on Amazon.com, but on the packaging it is in very fine print.

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.

My 2003 Ford e350’s horn went out, bought a wolo horn from autozone, horn didn’t work, well long story short order this kit and just bypassed everything. Tried to make all the wiring nice and neat as possible. Horn works we’ll button works well no problems. A bit intimidating if your not so sure what to do. I just hooked everything up first and then did a test before I ran everything through and around the firewall. One thing don’t forget to buy the relay, I didn’t realize this and ran to autozone to get one luckily they had one left for 7.50 so I’m happy now.

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.

Ease of installation depends on your application. The instructions can only be read with a magnifying glass but if you order the wiring harness, which I recommend, it comes with better instructions. Its LOUD and is working out nicely on my Vulcan Voyager.

اذا شتتريت الهرن للشركة نفسها انصحك تاخذ القطعة هذي بتوفر عليك عمل كثير .

No relay included

buena calidad y llego muy rapido

Am glad i found this kit. All needed is there, instructions are clear. Wish the horn came with this kit. Not for the money, just did not know this kit was available!

Installed this kit on my commercial truck. Very easy install. Great instructions and works perfectly. Helped me stay MTO compliant. Allowed me to use an aftermarket steering wheel without horn button. New horn button mounted in my dash panel.
