Tinobw & jaespark87 can you please talk over PM messages, I want to keep this thread nice and short so other users can read/accesses the information without having to go through many pages.
Updated with Bi-Xenon information.
If you add the shutter wire, you will have bi-xenon, meaning you will have 2 stages of brightness. Regular low-beam xenons, and high-beam xenons. If you do choose bi-xenon you will have the choice to have low-beam and high-beam xenons and regular high-beams together.
If you do not choose to do this mod, you will have regular high-beams(h7) and just low-beam xenons.
This will not cause an error.
