may not be in order but this is definatly a list of thing you have to do. Havnt actually done this on a civic but did it on my supra and they are exactly the same.
1. remove the bulb holder
2. remove the bulb
3. plug the bulb holer into the HID unit
4. plug the HID bulb into the HID unit
5. attach negative of the HID unit to the battery
6. attach positive of the HID unit to the battery (do this with the inline fuse out)
7. push the inline fuse in
8. Turn on your lights
I'm sure someone will post after me if anything at al is wrong.
Hope it helps
