I messed with it till I figured it out. Here's how it's done basketcase. First thing to do is get the wiper knob off, which is held on by a small set screw. Then the headlight switch knob is a little trickier. Reach under the dash, and on the top or bottom of the switch there is a little button. Push it in and hold it, and pull on the knob. If you play with it enough it will come off. Then unscrew the chrome bezels around the knobs. Next, reach under the dash and unscrew the speedometer cable from the back of the speedometer and pull it out. Once you get that out, remove all of the screws around the instrument panel and slide it out some. All of the wiring is on a nice harness that you can reach easily once the gauges are pulled out some. Unplug the harness form the cluster and you're home free. I got mine out in about 20 minutes with no instructions, so you should be able to get it out pretty quick. It really isn't that hard. Reinstallation isn't tough either, just be careful not to scratch your steering column when reinstalling.
Good Luck and God Bless,
Brian
