Whats the difference between 94 and 99 gauges clusters??

I've heard of people using the clusters from Bullitts, so the Autometer one should. Our cluster is electronic, it just doesn't get any info from the main PCM. Considering that the Speedcal and other add on type devices will work on 99-up cars just as they do ours, it seems like the info from the main computer is secondary info and could be done without.

This is just a guess, though.
