yea I have the ddm tuning hid kit's in my headlights and fog's but from install I haven't figured out why if you have your lows and fogs on at the same time and switch to your high beams and go to turn them off with your nob for the fogs still pulled out it keeps the high beams on and just turns the fogs on so in order to get your low beams to go back on you need to turn the lights off and turn it back on, Not sure if it's something in the hi/lo relay or what just curious if you had the same issue i have a buddy at work same truck as me has the same issue..any information will help
