Hello everyone. I just purchased a 2012 Explorer. It did not come with hid headlamps and I would really like to have hid in this car as all my other cars came with them. Now my question is, I have sourced OEM hid headlight housings with the bulbs and ballast, now can I just remove my headlight housing and install these housing with out a problem or will I need to rewire some things? Thank you in advanced!
