N. Hodges,

I did partially disassemble my instrument cluster but I didn't see any bulbs on the circuit board itself. All bulbs in my cluster (i.e. warning light and illumination) seem to be the twist out variety.

The AllData electrical diagrams cover some--but not all--of the instrument cluster wiring. (Some wires lead to a rectangle and the details of what goes on inside the rectangle are unknown.)

A detailed MB schematic of the instrument cluster would be a great thing to have.
