I have a 97, and I am putting a 95 instrument panel in my 97 (more gauges), and I can tell you that there are a bunch of little lights in the instrument panel-- one for each instrument. I think the 92's are very similar to the 94-97 birds in that respect.

If there are no dash lights, most likely you need a new light switch and/or dimmer switch (I'm not sure if the 92's have the dimmer switch).
