box located on back of gauge cluster

on my 67 el camino, on the back of the gauge cluster there is a silver box, about 1"x2"x1-1/2" its silver, looks _like_ a relay only writing on it is a "12v" stamped on it, there are three prongs coming out of it, its not hooked up so i cant trace the wires, im wondering what this box is...

This could be a voltage regulator, some old guage clusters required a stable supply voltage for the instruments, electrical fuel, temp and oil. A regulator was often fitted to the rear of the cluster and had a 12v ignition supply to it, then out of it was a stable 12v (sometimes a bit less) for the guages. This stopped the instruments moving up and down irratically due to charge variations and other loads. With todays improved alternators and charge sytems the supply is usually taken straight from the ignition.
Hope this helps.

i HAVE A 66 AND A 67, they don`t have anything like that.
With no wires connected, hard to tell.

Arrow

Sounds like constant voltage unit (or regulator) , they were used to keep the gauge voltage level so that they wouldn't fluctuate with the charging current. If the gauges start getting weird (for instance the temp gauge,fuel gauge,oil pressure gauge start getting high readings at the same time, or low) it probably needs replaced. They were pretty common for many years.
