Here are some pictures of my HID setup on my 01 Camry...sorry I've dropped my dig camera too many times, so it's kinda blurry:
I purchased a new set of Camry lamps today (last 2 pics) which I will be replacing the old ones with because they are slightly hazed....then I will use the old ones to experiment with my projector retrofit in the near future.
One cool thing is, that the HID Ballast power plug fits into the 9006 harness, so it snapped right in....but I will probably upgrade the harness before I take it on long trips.
