Basic hand tools - all the normal stuff to remove the shifter console and the radio/HVAC trim piece (screw driver, allen wrenches, wrenches to remove shifter handle), plus a few sockets (15mm and 13mm deep take care of most things). Removing the front seat makes things much easier, and you have to drop the steering column...it's just two nuts on either side of it that lets it hang down pretty low. Once you have that stuff done, I pulled the dash trim out starting over by the radio and working my way around to the driver's side door. It is mostly held in place by clips. Once you have it out, the gauge cluster is just a few screws away from being out of the car.
Before you put the trim back in, test everything to make sure all the bulbs are in there correctly...LEDs are polarized, so they'll only work one way. If it doesn't light, just turn it around 180* and try again.
Time consuming, and a bit of a pucker factor when pulling on the dash trim hoping that nothing breaks, but it really isn't too bad. Took me about 2-3 hours, and I work SLOW.
