After the above is done, have the dealer program the Xenon = Present, or the HIDs will flicker and stobe like crazy (which is very bad for the lights). I just left the connector to the lamp unplugged and drove to the dealer in the day time.
Here is another way to do this install without removing bumper. Turn the wheel all the way to one side, and remove screws in the wheel well. Pry open the plastic cover and you will have all the access you need.
I covered all the connection points with heavy duty electrical tape to prevent moisture.
