quick question - on any 12V cigarette lighter accessory plug, there's the springy button connection on the end and then the two connections on the side. what are these connections? is the button positive power and the sides grounds or something? i need to know. i've searched the net for the past 30 min to no avail. i'm rewiringsome neons/LED's that i have into a power switch, but i can't figure out the wiring. rsvp asap!
