on installing aftermarket horn? I saw a video online for the Wolo Bad Boy and using the relay to prevent burning up the switch, he had to remove the tank and route the wires funny.

Anyone do a plug and play install on anything louder than stock and not have any problems?

 

You can google a relay and get a diagram. Are you sure you need a relay with a wolo? Someone might have used one, but is it really necessary?

 

A relay can be a very good idea when installing anything with a higher current draw than the stock circuit, whether it is air horns or lights.

the H-D air horn wiring instructions are comprehensive, download them from their site

I'm interested in this thread also.... as the stock horn really needs upgrading !!
I was thumbing through a J&P Cycle mag and stumbled across a PIAA "sports horn".....
I may do a little investigating on this one. Peel the stickers off the plastic and paint it.....
Not sure about the wiring needed.....may need more than the simple 'plug-n-play'

 

on my FLHRC and it was a breeze. It is a plug and play but it does require a second hot lead to be connected directly to either the battery or accessory. This enables a 'instant' reaction to the horn when the button is pushed.

 

I replaced the stock horn by 2 FIAMM Freeway Blaster (hi and lo tone). They're loud but not obnoxious and they sound like an italian sports car.

I mounted them behind the saddlebags, in front of the shocks, one on each side. They come with mounting brackets.

I didn't want to bother making my own harness so I bought one already made by these guys. I picked the dual horn relay kit. Great people, high quality product and great service. The harness comes from Japan (the owner is American) and I got it in 1 week.

It took me 1hr to complete the whole project and I took my time to find the perfect location for the horns. The harness connects to the stock switch wires under the cowbell so it's a breeze to install.

I bought the horns from www.ryderfleetproducts.com They cost me around $20 shipped. They are also available at Advance Auto Parts, Autozone, etc...

 

I installed a wolo bad boy air horn on my Wide Glide a few years ago. I installed it without a relay to start with and did smell my wires trying to burn when operating the horn for over a quick toot. I had received a relay with the horn so I ended up wiring that in the circuit. I ran wires along the factory route to under the seat. I did end up spraying it directly with water one time when I had my seat off and washing the bike. I then used the horn and fried the relay, the good news is I was able to go to AutoZone and get a new one for about 5 bucks. So I would say if you dont want to take the risk of burning up your baby (bike) you should definitely put the relay in and not take that risk. You put too much heart and soul (and money) into your bike to take that risk.

Edit: Oh sorry I just read your origional post. You wanted to know about plug and play. I pretty much made my own. It is about like a plug and play wiring harness. I taped all the wires together and put spade connecters on them so that I could just slip them on and off. In the end I was glad I did because my relay swap took under 5 minutes.

 

I am a Mini-Beast Air Horn Fan....have used them for years....simple plug and play...very loud. They have saved my hide numerous times with cagers....especially good at stopping that Yukon driver on the cell phone.

 

+1. Pricey - but I love mine. Sound and look.
