A Hayes manual will tell you... although not very well. You have to take off the black trim first. To do this, pry out and disconnect your clock and hazard lights. Next, undo the screws on top of the trim by the guage cluster. Then, pry the black trim off with a screwdriver. Use another screw driver to push on the little black clips holding the trim on. Be careful! I broke my last trim doing this and had to get a new one from a junkyard. When the trim is off, you can just unscrew the guage cluster and disconnect it from its wiring harness. Just take your time, be careful, and don't force anything too much.
