I used this for the fog lights. A simple schematic would help. It comes with nothing. The terminals are very small and very close together. I soldered wire pigtails to it and used heat shrink tubing to make sure there weren't any shorts. Nice switches and for the money they are excellent. Note, however, that the switch light (mine is blue) is very bright. Of course there is no indication if they are dimmable or not but I plan to add a dimmer to them.
