Pop the dash out and you can get to it. It is right behind that knob that dims the dash.
If you do not wish to use the dimmer, then remove the porcelan square assembly from the rear of the instrument cluster. Takes a philips #2 screwdriver to take it off.
Then either replace it., I believe I have seen them here, of I just used a wire with two round things from a Radio Shack kit and pushed them on the two metal posts that will remain after the other stuff is removed. Like I said, not hard to do.
