Are you just installing them in your headlights? Adding projectors as well? The halo's are usually meant to be added around projectors.
In any case, I would wire them to your parking lights. Just splice power off the side of the parking light wiring and attach it to the angel eye ballasts. The halo ballast should have a red positive wire and black negative wire, so whip out a multimeter and find you which wires on your parking lights are positive and negative.
