Remove the two pieces that surround at the door. The piece at the top should be metal and the other bigger piece plastic. These pieces are relatively easy to remove. There are no screws to loosen, just little flaps of plastic that slide in behind each other. Just gently lift and pull and you will see where they are, and remember how they come out, they have to back in. So now you should be with a couple pieces like these.

Gently pull the rear side panel out. It is being held against the body of the car by one of those white plastic bolts with the big threads. Pull it and it will pop out. Now I did not go to the trouble of taking out the whole rear panel. I opened it up enough that I could get in behind with the screwdriver. If you pull the rear panel towards you and look behind it, you will see the nine tabs you need to pry straight. Once you have them all straightened, your panel should now look the second picture below.

Proceed to trace the outline of your removed panel onto your newly acquired vinyl leaving about ¾" all around the side. Once you have your piece traced and cut out, pull the material tight and start to staple the edge to panel. Use as many staples as you want, I put them almost one beside the other, but you can space them out if you would like. Make sure you keep the material tight any time you are setting a new staple. Work your way around, I started from the bottom center and worked counter-clockwise. When you get to the corners, slice the material into strips to pull it tight so you don't get any bunching. Please see the Door Vinyl how-to for more information on how to wrap the vinyl.

Replace the newly upholstered panel back into its place and bend the tabs back, I just used my fingers to push the tabs down. Be sure to push the colored piece in with your free hand so it stays in tight. Reverse the removal process for the two pieces you removed earlier, and be sure to push that white bolt in after to secure the panel to the cars body.

Step back and enjoy. Oh, and do the other side ;)
