Wolo (419) Bad Boy Air Horn - 12 Volt , Black

I bought 2 of these horns. One for a scooter and one for a Honda Goldwing. For the scooter, because of space constrictions I had to separate the air pump from the horn and mount each piece in a separate location and reconnect with vacuum line after adding a hose barb to each piece. Goldwing install mounted great. I mounted it behind and above front wheel fender in front of the radiator in the blank space between radiator halves as far up as I could. I have it turned vertical with horn opening on the bottom facing forward and it blocks very minimal air flow. I had to epoxy 2 strips of stiff closed cell foam to the horn, 1 above and 1 below the round chrome looking piece so that the back was flush and kept pressure off of round piece.Then I used heavy duty zip ties around frame piece in between radiator halves. 600 miles on Goldwing so far and all is great. And it sure is a BIG sound coming out of a little scooter. Makes me laugh.For both installs I left original horns hooked up as well so you get 2 different tones which makes it that much more noticeable.The horn itself works great. i purchased additional relays after reading about early failures with included relays. Just as a test for the Goldwing horn, I connected it to original horn wiring and then 2nd test I wired correctly and connected it straight to battery with the relay. It is quite a bit louder coming straight from battery with relay. And this is also the correct way to install it as the stock horn circuit is not designed to pull the power required for the pump. Hence, the quieter horn. I have read that some just use stock wiring and all is good but the relay install gives you more "bang for the buck".

I'm glad that I replaced the OEM horn in my 2000 Miata with the Wolo Model 419 Bad Boy Air Horn. The OEM horn sounded like a bicycle horn & wouldn't scare a child. The Bad Boy has a louder two tone sound, like much larger cars and you will not be ignored anymore.The only difficult task was removing the existing OEM horn & bracket. I had to remove the Miata grille (screen) and one passenger-side headlight bolt to gain access to the OEM horn, mounting bracket, electrical wire & wire clamp.I used the previously removed OEM horn bracket, after drilling a 1/4" dia. hole (near the bend in the bracket)for the Wolo Bad Boy horn kit included mounting bolt. See the customer images for approximate hole location & installation photos. I mounted the OEM horn bracket with the existing bolt on the radiator mount. The Bad Boy horn tucks nicely tucks in this area and is easily accessible. See customer images for installation location.Wiring-I used the existing OEM wire & clamp. I cut off the old wire connector & then crimped on a new 3/8" insulated female spade terminal. This wire lead connects to the plus(+) Wolo male spade. There a existing hole in the car frame where you can insert the existing wire clamp to anchor this plus (+) wire lead.I purchased some 16AWG wire for a chassis ground (you will only need about 6" of 16AWG wire). I crimped a 3/8" female spade on one end (which connects to the minus (-) Wolo male spade). Then I crimped a 1/4" vinyl insulated ring terminal to the other end of the ground wire. Note: Attach both plus & minus wire leads to Bad Boy horn before securing the horn to the OEM bracket with the bolt included in the kit.I cut about 3/8" off the Wolo mounting bolt, so that the threads would not protrude so close to the radiator (this is totally optional). Next tighten the Wolo mounting fastener nut to secure the horn to the OEM horn bracket.I used the original bolt (that secured the OEM horn bracket) to secure the ground ring terminal to the car frame. There is an existing threaded hole in the car frame where you can terminate the ground wire [from the minus (-) lead from the Wolo horn]. See customer images for installation location.To insure that the Miata electrical system would handle the increased current, I replaced the existing (15 Amp) horn fuse with a 20 Amp fuse. The fuse box is located in the passengers' side of the engine compartment near the wiper fluid container. Note: The horn circuit is the same as the stop light circuit. It is indicated on the top of the fuse box as a "Stop 15A". See customer images for the fuse box & notations.Hopefully this will help other Miata owners to install the Wolo Model 419 Bad Boy Air Horn in your vehicle. I am glad that I took the time to do it, because I could not stand to hear that annoying little OEM horn any more. The Wolo horn is relative inexpensive and well worth the money when purchased at Amazon.com. It is normally $39.99 at Harbor Freight.New Parts Required Summary: (1) Wolo Model 419 Bad Boy Horn Kit, (1) 20Amp Fuse, (1) Approx. 6" long 16AWG wire, (2) 3/8" vinyl insulated female spade terminals and (1) 1/4" vinyl insulated ring terminal.Good Luck,J.

I bought this horn to use on my dirt bike (motard style). Wolo advertizes that their horn will fit any bike, but it was very difficult to find any place to mount it on a dirt bike, as the horn is quite big. I emailed Wolo and asked for help about where to mount it, and they weren't very helpful - just said that my installer would have to find a dry place to mount it. I finally decided to mount it over the headlights. I then emailed Wolo asking for advice buying or making a rain shield. They didn't answer any of my questions about what materials to use in a rain shield, but mentioned a company called Metal Arts, but when I did an internet search, nothing came up. I emailed Wolo again, asking for a url or email address for the company and they gave me a phone number for the company. Since I live in Thailand, I wanted to contact the company by email, so I emailed Wolo, again asking for that information, but they never answered my final email. I finally designed a bracket and rain shield my self (the bracket from stainless steel, and the shield is an old helmet face shield). The horn is excellent - very loud, much louder than even the horns used on cars here in Thailand, so it really gets other drivers' attention on the highway. I had a switch installed so that I can switch back and forth between the Wolo horn and the original horn, so that I can use the quiter horn in town and not cause someone to have a heart attack! The relay went bad after a couple of months (the mechanic who replaced it says it was a cheap Taiwanese relay.) I've been using the horn for 9 months now, with no operation problems from the horn itself.
