I've got my garage door opener wired into it because I couldn't see that blocking it would get in the way of anything. It's a perfect spot for an accessory outlet if you have heated gear. I'm guessing it was originally intended for that and they changed to the phone charger under the seat (right next to it) because it would use less power - but anyone's guess is as good as mine. I can use the other half of the switch for a constant on source - but I haven't decided if I want to use it for heated grips, additional LED lights, a headlight modulator... I'm going to mount the Stebel horn and the LED battery gauge that I already have - and hold off on anything else till after Christmas.
