They work just like regular headlights, unless you get a s*** set of ballasts that don't fire with the auto on feature. You don't have to run a switch or anything, they plug in to where your factory bulbs plug into.
Some cheaper/crappy kits may not fire with the auto-on feature. Personal experience, mine work fine (cheap 60 dollar ebay set), your mileage may vary.
I usually just turn them on manually anyways, I rarely use the auto on.
