Remove the upper corner screws first, and then the lower bottom screws second with a Phillips screwdriver. The lower bottom screws are hidden underneath the two square plastic tabs (caps)...you just need to pry them off with a flathead screwdriver, and then you'll have access to the two screws that's holding the instrument cluster lens. I found out myself by trial and error, nobody told me. This is how you reset the red "maint req'd" light that comes on after a preset mileage to remind you to service your Mitsubishi Mighty Max pickup truck. I own a 1991 Mighty Max myself and I perform all routine maintenance on it....I hope this pointer helps.
Remove the instrument cluster cover. Each instrument gauge is secured separately with retaining screws. Remove the retaining screws from each gauge. Remove the wiring harnesses from each gauge.
The gauge cluster is mounted from behind the dash with three bolts. You have to reach in behind there and remove the three nuts with a small wrench. Once you remove the nuts, the gauge cluster itself will push back through the dash. From there, you can remove the speedo itself from the cluster. The speedometer only has 3 small screws keeping it mounted to the gauge cluster.
Two screws at the top of dash and one screw each behind the flasher switch and a cover plate on the other side from the flasher switch. Reset switch in at the bottem right of the gauges after removing trim. Slide swith to reset.

Remove 2 7mm bolts on instrument cover plastic. remove this part exposing the 4 7mm bolts that hold in the cluster then carefully remove instrument cluster from dash. On the back of the cluster you can remove the bulbs by turning them counter clockwise and pulling them out. Bulb number 194
Take off the gauge cluster trim. Two screws on top, take out the hazard and other switches below the cluster to get to the two screws behind the switches, and there will be a small switch in the lower right corner, simply switch it left or right. The light will come on again at 120000, at that point, remove the bulb. REMOVE TRIM COVER FROM RIGHT LOWER DASH, YOU WILL SEE A SMALL SWITCH. USING A LONG SCREWDRIVER YOU CAN MOVE SWITCH AND RESET EGR LIGHT.
