Trailer Hitch Install/Rear Bumper Removal

[X3eme]

I want to install a factory trailer hitch myself and I have most of the instructions, but I still need them for removing the back bumper. I have spent hours searching all of the forums but have come up with pretty much nothing.

Does anyone have any instructions on this or maybe a TIS page that shows how to remove the rear bumper? I bought a TIS disc on ebay, but keep getting application errors with it. A screen shot of the TIS page would work. Let me know if you need help doing that.

Any help would be appreciated. I will take some good pics while doing the install...

Thanks!
