I installed mine over the weekend and a comedy of errors happened.
First off, I used the instructions that came with the part. That was mistake number one. Here is how the instructions say to wire:
Everything is correct except the white wire. As the OP posted, and for some reason forgot the thread existed even though I posted in it, the white wire goes to the green and white factory wire.
After hooking everything up and having my wife come out and hit the brake and put it in reverse I finally looked here and saw the error of my ways.
That evening as I am moving the cars back in the garage I notice that my left rear running light is out. Mistake number two and fanfuckintastic. Sunday afternoon I start ripping everything out again to check all the wiring. Sure enough, one of the connections came loose. After neatly packing the wires back together, I used roughly 6000 linear feet of electrical tape to make sure it doesn't come loose again.
I bought the smoke lens option. If anyone is interested I can take some pics of day and night so you can see.
The lesson here is use this thread as the install instructions.
Side note: There is a bracket the is connected to the frame that holds the bottom of the bumper in place. I found it easier, albeit a little more time consuming to remove the bracket. It is held into place by three of the plastic push clips. By removing the bracket you are able to get a socket onto the nuts that hold the reflector in place. The factory put roughly 15 metric tons of locktite on the two nuts holding it in place, thus my need to remove the bracket.
