Please see the google doc link for the DIY for US spec F30 OEM adaptive Xenon retrofit. It is 90% complete and I work on it a little each day, but it is more than enough to get you started. I have this in my car for over a month now with no issues. I am still in the process of getting the auto level sensors to work, but should not be much longer.
