My car was halogen as well. I added the add'l ground req for xenons using factory parts. Moved the pin for the high beams to enable the shutter mechanism. The only other modification was a capacitor added in-line with the power from the factory harness. Was a clean install as I am ocd when it comes to wiring (used to install car stereo back in the day).
