This isn't exactly step-by-step but here is what I remember from my install:
1.Remove battery.
2.Remove plastic radiator shroud.
3.Remove computer behind airbox.
4.Remove airbox.
5.Remove original bulbs.
6.Trim covers to bulbs to run wiring through.
7.Install HID bulbs.
8.Run wires through cover, install cover and seal hole,
9.Find nice place to mount ballast. I put mine inside of a little pockect that is next to the radiator, there is one on each side.
10.Run the wires necessary to the ballast and bulbs, per the directions given.
11.Hook battery up to test bulbs.
12.If both turn on, reinstall parts.
13.Remove DRL relay from fuse box in engine bay.
14.Go find a wall in front of a flat surface and make sure the lights are even.
I hope this helps. If you have questions just ask. Don't be dissapointed by the light output because the factory halogens are good. The look of the HIDs can't be beat, you will get a lot of looks when you approach people from behind at night.
