well if your using a separete switch all you do is run the positive wire from the lights to one prog of the switch and the other prong to the battery and ground the negative wire of the lights.

i have the spyders and i have wired my halos wired in with my foglights, so the with the first factory position being off, parking lights are on the second position, then when the foglight switch is on the halos and foglights are on, then the headlights on the third switch position
