Hi, reviving this old thread. I need to adjust my low beam vertically and as per the photo, that plastic hole doesn't have anything in it. Can anyone help! Thanks

Hi All, I am thankful for this thread even though this is a really OLD, I managed to successfully have the steering wheel control work and display button. I am installed a generic android head unit. The display button wouldn't work when the steering wheel control cables is not connected to the headunit. I have connected directly the Pink wire to Ground, Orange and Yellow to either Key1 or Key2. Saved me from forking out a $99 Aerpro steering wheel adapter. The AC controls connected or not wouldn't affect the display button functionality. I appreciate the help guys.
