I know this has been talked a lot. I've searched but seem to never get a clear answer.

21' Sport Glide....stock horn is worthless. I'd be happy with the same loudness of horn I had on my 14' Street Glide (which BTW was also a BCM system) PN# 69060-90H

I realize that I will need to build a bracket, but will the stock power feed make this horn HONK to it's max potential?
If not I guess I need to get a Wolo Air Horn with a relay harness, and find a place to mount it.
Photo's of what worked for you would all be great. Thanks for helping an Old Guy out!

 

if it were me i would go to any parts store and get one

 

"one" of what type?

 

horn for a car it will or should fit. they even have chrome one's. not sure of the price. pull up any of the parts stores on the net and look at them.

 

This works for me. Used the supplied bracket (strap) to mount. It will clear a Harley crash bar.

 

Thanks Mike, so does this one sound like a horn and not like a road runner that got it's beeper stuck in a lunch sack?

 

It's the low tone one.
I had a 2014 Street Glide with the loud horn so I can vouch for this one.

 

$20 at Amazon. You get 1 high note and 1 low note. Loud as hell.

 

Did it mount right up or did you have to modify anything?

 

No modification at all, it took 10 minutes and done. It's not as big as it looks in the photo either

Here it is ---
