Put mine in a few weeks back.
FYI, in order to get the bulbs to lock into the housing (if you are still using stock) I had to cut a few chips out of the 'weather cover' or in order to push the HID in all the way...you will see what I mean when you try to put it in. I zip tied the boxes to existing stuff under the hood. I also had to run the ground from the passenger side HID to the battery b/c I didn't have anything to ground it too on that side...so I just ran it back over and wire tied it with the other wires randomly going in front of the engine (watch out for the radiator fan!!..haha).
Overall the lights work well. I have been bright-lighted once and that was by a miata that was probably staring directly into them. I will post some pics next week...been swamped lately.
Also, you can download the directions off of DDM's site...super easy. Took me less than an hour to do everything...first time to do anything like this.
Disable the DRL's and when you do make sure it is the correct wire...there are 2 yellow/black wires...I mentioned it in the thread below I think.
