Adding Stiebl Dual Horn package with Wiring Harness

One of my Winter projects has been to update the noise capability of my 2001 C-10.

I had been reading about Air horns and the installation process seemed more involved than I cared to handle.

In October 2015, my cycle was knocked over in the parking lot at work.  Since I needed to take off the fairing in order to work on horns, this accident seemed like a good opportunity to get at them.  Once I stopped riding for the season on December 22nd, I put up the bike to work on fairing replacements and new horns.

First, I ordered a replacement Fairing from PartZilla.com.  A new upper fairing took two tries from Partzilla to ship one safely.  The first fairing came with a crack in the mirror area that I was needing to fix.  Oops!  Another visit from the UPS guy delivered a second fairing with expanding foam insulation protecting this shipment. 





Second, I ordered the Dual Horn package with the Wiring Harness.

The horns came in one box without distinguishing which was the high tone and which was the low one.

Original package

The wiring harness came with one sheet of directions, one side for using two horns, the other side for three horn or four-horn hookups.  The wiring harness is well constructed with a good relay. I cut the harness halfway to the battery so I could remove the fairing using quick disconnect plugs.  Otherwise, you'd have to disconnect the wires from under the tank to the battery if you needed to pull the fairing and fairing stay.


Once I figured out myself that four-horns set up still used one original connection and the other connection was used with the wiring harness, the only other issue was how to mount all the horns.
I mean there are four 3-inch standoff steel arms that could be used by others bikes to hold the horns but I needed pipe hanger steel to hold the horns farther away inside the fairing stay.  The hanger holes were drilled out 1/8" to accommodate the larger OEM horn screws.




This is the view of the new horns in the OEM horn position.  They needed different washers for me to hold them in place because the horn mounting screw was shorter than the OEM horns. They fit right in the same holes as the other horns.


The noise of the four horns is definitely louder in volume.  I cannot tell the tonal change with the newer horns present.

There will always be a goofy driver who will wander if front of my bike that I will have to chase away with these Loud horns.  :-)
