Remove steering wheel first. To do this, you pull the center off, and loosen the big nut holding the wheel . You need to have the ignition in the 'on' position, so the wheel is free to turn. You do NOT want to try to turn against the wheel lock. Trying to work against the steering wheel lock will break that, and that's expensive, aside from being a severe pain.
Get a piece of wood, and brace from one of the wheel spokes to the floor. Pad the end at the wheel spoke with a rag or some such. If it's never been off, it may require a bit of torqe to get it loose, but that's why you brace it.
Once the wheel is off, you have complete access to the cluster. If you can't wiggle the cluster out, there are some hook tools available that let you slide them in, turn, and pull.
While you're in there, change out your light bulbs and add an additional ground lead from a screw holding down the circuit board to a convenient bolt on the frame behind the cluster. Put a male/female connector in the lead for future re-entry.
Be very careful with the oil line. Whatever you do, DO NOT try to start the car with the cluster out. You will have a pressurized oil line pointed at your chest. This is not good.
Remember: It's not just a car. It's an Adventure.
