I hate to say it, but I didn't take any pics because the process was fairly straight forward. I learned how to take the spoiler off from some other threads on here, but in a nut shell you take off the inside of the tailgate using a torx bit, on the back side of the latch are a clip and a nut which have to be undone. Then take a flat very stiff putty knife (steel because I don't think plastic would hold up) and run it along the back top side of the spoiler to get the double sided tape to come undone. On a side note if you figure a way to get the old tape off easily let me know. Take the back edge of the spoiler and pull it towards you (standing in front of the tailgate just like you were going to open it. You won't break the spoiler, but you will break all six of the clips underneath it. You'll have to order a bunch of them. I got them from ebay and they worked perfectly. The part number for the clips is GM #11611626 and here is an ebay link because the dealer charges $4/clip. http://www.ebay.com/itm/111902536539?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
Now, don't do like I did and lose the bolt to the nut that goes on the inside of the spoiler just below the latch. It's in the stone in my driveway...somewhere. If you have the factory camera it will be attached to the spoiler so you can unhook the pigtail and take the spoiler off. The camera is right on the back side of the spoiler and is held on by two screws. You'll have to jury rig a little platform for the new camera to stand up on because the factory mounting spot is a little tall, but a piece of wood or thick plastic will do (probably about 3/8 inch will work). Get a big roll of the double sided tape from Amazon http://www.amazon.com/gp/product/B0026HOTZ2?psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00
Splice the camera, mount it, reverse the spoiler process. That's it.
