I really didn't need a spudger to pull the cables off.
My thermal sensor was magnetised. I just pulled it off my old HD and put it on my new one. It sticks perfectly to the metal casing.
The inverter connector had a different location for me. It was situated next to the top left corner of the right speaker, just under the display. I didn't figure this out until I actually lifted the display off the computer.
Step 4 is completely unnessecary. Just lift the bezel up and wiggle it until the metal clips let go. Then lift the bezel straight up.
