I am interested in finding out the easiest way to get power to my Garmin Nuvi 660 which I have mounted to the handlebars of my 2006 Vulcan 900 LT. I understand that there is power in the headlight assembly but I am not sure if I would have to use a cigarette lighter to wire into the assembly, or hook up a direct power link, and what wires I have to hook up since there appear to be a few color coded wires in the headlight assembly. I have absolutely no familiarity with 12 volt wiring. Is there a special wiring harness that I have to purchase? Is there anyone that can walk me through the process?
