Do the Aux gauges actually add anything? I've got oil, volt and temp gauges on my 85 on the cluster.

They are voltage and oil pressure gauges.
So in your case, no.

In my Indy, the tach had a volt meter, but no oil pressure gauge anywhere.

Thank you, I was wondering why it was an add on to GTs.

Not just the GT, all V-6 Fieros starting with the 86 model year.
