It's actually pretty easy, you have to remove the A pillar trim pieces, but there's "handles" on either side that you start with, pulling the trim panel up from the sides and working your way to the middle.
Be careful once you get to the center, because both the alarm LED and the ambient light sensor have pretty short harnesses. I had to twist in all sorts of weird ways to get them out of the old panel and into the new panel. The light sensor is the biggest pain, because if you aren't extremely careful you'll break the plastic bracket that the sensor locks into. It's only held on by two tiny little spot welds, and even just snapping it back down into place can break those sonic welds and it'll fall down under the panel.
