If ya think it's a mess now, you shoulda seen it before.
Ditched all the stuff I didn't need.
This included carb heat, tps, alarm connector, sidestand switch, wiring for non-existent light switch & other misc.
Eliminated three-legged wishbone in main harness.
Covered with split loom & braid vs. tape wrap (mixed emotions re: spit loom).
Added frame ground, dual electric horns, universal wall mount solenoid.
Ran engine wiring under gearbox a la '07, '08 models.
Battry cables are All-Balls brand.
Heavier than factory, but more flexible & nicer lookin'.

Made up stainless center hex studs to replace fender bolts.
One gets negative battery cable & the other gets harness ground.
Yeah, that's blood on the frame.

Fusebox power comes from positive battry cable at solenoid.
Just visible here crossing in front of the solenoid.

Added horn relay.
The rubber thingie that holds it is called a "relay grommet", P/N T2500259.
Hermy's has a bunch of 'em.

Engine wiring hidden.

The leftovers.
Kinda like cleanin' a trout (rabbit?).

Mixed emotions re: horns, too.
The sound is great, but the main reason I did it was some have said that you run cooler with the horn out of the way of the oil cooler.
&, I've since noticed that sometimes the stock horn is mounted with the bracket pointed upward, which looks like it does the same thing.
