I set mine up so they are powered off of the wire that goes to the little light, this way I am not forced to have the big light on while running the grips/more juice to the grips. 2010 300

My wife has a KTM 200 with a relatively small stator, I wired hers so she can turn off the headlight entirely and run the heaters, again sending as much juice to the grips as possible...... although they seem to work just fine with her headlight on also.

We both have Sicass Lighting Kits so our wiring is a little different but you get the idea.
