## Questions & Answers

**Q: Is it possible to use this with an electric wheelchair?  The chair does have 12-volt battery power.**
A: I would imagine so, but you would need to get a horn button and wire with the relay. Anyone familiar with auto electric shouldn't have a problem. Loud enough to bounce you out of the chair. good luck

**Q: Do I need to purchase other parts with this horn kit?**
A: Yes, you will need to purchase another horn from a different manufacture because they dont work and you will have wasted your time installing a broken horn right out of the box.

**Q: What does it sound like, a big rig, a monster beep, or something else?**
A: Not a big rig....but....triple the sound of loud auto and It Does get their attention.

**Q: Can this replace a to tone horn system? How?**
A: It has a two tone OEM sound similar to a Ford horn.

*by J***S on Reviewed in Australia on 12 November 2022*

This model came with no wiring and that made the job longer to fit.

### ⭐⭐⭐⭐⭐ 







  
  
    Nice Sound-Easy Installation
  

*by J***N on Reviewed in the United States on 2 July 2011*

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. Anderson
