I just installed my spoiler this weekend. It was fairly easy. The spoiler from eBay came with "locator strips" that you connect to the spoiler with tape, then put the spoiler in place, tape the strips down to the car and remove them from the spoiler. Drill the holes using the strips and install. You just pop out the plugs on the inside of the hatch and be careful drilling the hole on the driver's side because the tail light wiring is in the same area.
