I grabbed mine right where the harness from the bars goes into the frame. If you pull on it a little there is a taped off splice in the sleeve the wires run in. Just remove the tape and pull the sleeve back a little and you can get it right there without cutting that cover. The harness that runs to the headlights also comes out of the frame right next to it in the same hole. Making it easy to zip tie the new wire to that when running to the bulb. That way all your new wire is running inside the fairing.
Good luck and enjoy not having to explain to people that you don't have a headlight out anymore.
When in doubt just take a nap its easier.
