My car has bi-xenons, the ae's run off a separate globe.

the other options is to use an actual HID hit. They should be widely available considering it is a standard H8 globe fitment. (I believe some of the other members are running a similar setups)

The only issue is that it is a very tight space to get your hands in there to fit the globe. As for the harness I made a very small slit in the side of the covers of the head lights so that I could still close the enclosure and mount the harness elsewhere. I would do something similar if I was running a HID kit..
