If you want to wire your light bar into your stock headlight switch here is a fairly easy way to do it. First, you will want to use a relay. Hook the relay up like you normally do. But run the accessory or what I call the "hot trigger" to the middle of the headlight plug under the hood. Attached are pictures, yes my Talon is dirty, please forgive me. I just unplugged the headlight plug, and pushed the striped portion of the wire into the the slot where the two connect. It is the middle one. That is your bright light wire. Then plug the two back together. I attached a close up and a picture a little further away to show the location of the plug. Where you mount the relay is up to you. Many if the XTC wiring harness with a bus bar. Others have their own set up.
As for using a relay and plunging the acc wire into the headlight plug I have done this on several machines. It's really nice on ATV's since you really don't have room for extra switches.
