Yeah, theres 2 options really, you can mount the xenon lights like your standard ones, you'll need the plugs and silver controller boxes for the xenons, passenger one is attached to the bottom of the light, driver side on a small loom. Then you wire your old loom colour to colour on the xenon plugs, about four wires. From memory you need to connect the black wire to a switched 12v source to power the level motors up so they dont point at the ground. Bit of a bodge this way.
Or you can do it properly, you'll need the 2 levellers from the underside of the car too, both on drivers side attached to front and back suspension. Then wire them in fully, three wires each to the level sensors, a few to link the driver and passenger light, and two or three go inside for an ignition live and a connection to the MID and diag port.
