FD gauge dash: how the hell this thing works?

Ahh I see.

What you need to do first, is get the cluster to power up. Here's the FSM schematic for the cluster (you may have this already):

Go to page 46.

The connections are pretty self-explanatory. The tach connection is either the blue/yellow (4C) or yellow/blue (3F) wire, I can't remember for sure. The oil level light won't come on unless the wire is grounded, the coolant level light (and buzzer) WILL come on unless its grounded. If you are going to disable that, ground it to one of the ground wires in the cluster.

The ABS & Air Bag lights are going to come on. Best thing to do is pull the bulbs. When you pull the bulb for the air bag light, the cluster is going to make a faint series of beeps when you turn it on. It will take about 5 seconds or so for the beeps to stop and it will do this every time you power up the cluster. After a while you stop noticing it...its not like a coolant buzzer.
