I tried to link to a diagram but it won't work for whatever reason. Google image search 'tach install' and you will get what you need. It's very easy to do.
Typically for tach installation, there are 4 wires: The wire colors given here are for wires on the car, not for the tach. The tach wires may be different colors.
1). Switched power from the ignition - tap the red/green wire on ignition coil.
2.) Illumination - tap the light blue/red wire in the radio mount area.
3.) Tach signal - tap the dark green/yellow wire on the ignition coil.
4.) Ground.- find a clean, shiny, bare metal spot under the dash or in the radio mount area.

Sorry, I missed the fact that you had a 92, the wiring colors are different, The tan/yellow is the correct wire to use for the tach signal. If you wired up everything else correctly, the tach doesn't work...
