This was easier than it looked, the only thing I had trouble with was getting the cover off (tried to use a flexible palette knife, bad idea) and getting the little sensor plug back in (it's SO tiny.) Oh, and one screw I had trouble getting back into the hidden recessed hole because my screwdriver isn't magnetized.

Speaking of which, size of screwdriver matters, I bought a set with a size 0 and size 000, but no 00, neither worked. Fortunately I had one of those cheap eyeglass repair kits, and the Phillips screwdriver worked perfectly.
