Chris,
Make sure you have 12V at the gray wires going to the printed circuit
connectors - they feed the dash lights. Test for voltage to a good ground
rather than "across the fuse". Test the instrument cluster ground (looking
at the wiring diagram, it has a bunch of black wires going to it)
Just some ideas,
