Any one seen gauges with this??

You should be able to trace the circuit back to the connector and then check the wire number/color to the schematic to find out what they are for.

just a thought, but can't you shine a light behind the overlay and see what symbol is there??

My wiring schematic for a 91 burb shows it as a canadian daytime running light and a low coolant sensor on diesel models. When i swapped to this cluster i used the batt light instead of the resistor wire because in the past i have had the resistor wire smoke.

i see, then i agree with Snoots that by tracing the wire back to the connector, you will know what they are for...
