First eliminate what wiring up top you can.
I run right side switch only, that means hand signalling, and no e-start, or e-start in horn button, and bulb horn, also you must run 72 or earlier rt side switch, has off/Hi/Lo for lights.
Then I run the wiring junctions under the headlight, fold some unused back, end up with a taped up lump around an inch and 1/8 or so in diameter.
