If I remember right:
1 Take the four screws off the face of the gauge carefully. They like to strip out.
2 Reach way behind from the floor and pop off the speedometer cable from the back of the gauge.
3. Pull on the gauge cluster and work it loose so it wiggles in the dash.
4. Work your fingers behind it and pop loose the wire plug that runs into the gauge.
5. Pull the gauge cluster out.
6. See all those little black twisty knobs? Turn them about 1/4 turn and pull them out.
Inside them is a bulb. Just pull the old one out and push a new one in. Lather, Rinse, Repeat!
