Here is a troubleshooting video to test your gauge, fast forward to about the 8:30 minute mark.

Just to check, since I think some 81s had two temp gauges.
Does your 81 have a clock, or an oil temp gauge? Is it the oil temp gauge that is the problem?
I found a bent pin in the connector that goes into the back of the flexible circuit board on the center gauge cluster of my 80. I bent it back, and that fixed one of the circuits.

To ensure the wire from the temp sensor is not damaged, simply attach a temporary wire from the sensor to the gauge.you will need to get 12 volts from some place, how about the cigarette lighter. Make real sure you have any exposed positive wires completely taped/ insulated.
