Well, if the horns are under the front fairing, and the harness is right behind them...sorry.
If you don't mind a bulky splice you could go into the button wire on the left bar, but that still leaves you with removing the stockers...under the front fairing....
C'mon, it's not that bad really, and it gives you a chance to do a really good cleaning in that area, inspect the main fairing stay, install some bling marker lights where the reflectors are....honestly, I had the front completely apart for paint in less than two hours, and I'm about the slowest person on earth in the garage.
