2011 Vaquero 1700 Air Horn
So, this weekend I installed one of those WOLO air horns from Discount Auto on the Vaquero.
Honestly, it was pretty easy to install. I hooked it up with the supplied relay. I wasn't sure if it was safe to use accessory power or not (Or where exactly I might find accessory power on the front of the bike), so I just ran a wire for power direct to the battery (with a fuse, of course).
I installed it using the same bracket the OEM horn used. The thing that took me the longest was bending that bracket around until it was in just the right position and I was happy with it. If anyone else does this, save yourself a trip to the store and pick up some of those star shaped lock washers. The weight of the horn on the bracket was causing a problem with the bracket slipping.
After hearing how loud the horn was, I've got to admit I laughed my way through the rest of the installation.
I'd be curious about alternate mounting positions folks have used, specifically on the Vaquero.
