Mine has wires to it and they where power, ground, switch light inside the button when headlights where on and a light that comes on when the switch is in the on position. However, hidden from the view from above, was one leg on the bottom of the switch had no wires connected to it. This was the power out to connect to what ever you want. I connected a triple 12V socket and mounted it under the dash, and plugged my Garmin GPS and Sirrius Sat radio to it, turning them on/off with the AUX switch. Both my 05 and 08 Dolphins came like this with nothing connected to the 12V output pin of the AUX switch.
