I finally got around to reinstalling the temp gauge needle on my 88GT.

The only way I could figure to gain access to the gauge face was to completely remove the instrument cluster pod and then remove the instrument cluster from from the pod to gain access to the top screws of the clear plastic cluster face.

I plugged the cluster back in and using Rodney's temp gauge calibration pigtail I set the needle at 100 deg F with the one wire connected. I then switched to the other wire and it correctly showed the other reading (I think it was 260 or so, can't remember offhand).

With the key off the needle rests at the left edge of the gauge below 100. When I turn the key and get bulb check the needle snaps to around 105 deg F position. As the engine warms up the needle stays at the same 105 mark until I turn off the key and it returns to the left edge of the gauge.

I had replaced the plug at the sender. Could it be that I possibly got the wires crisscrossed in the plug? Is there a way to check the sending unit to see if it is putting out the correct resistance?

Thanks

Swap the wires at the sender, you prolly have them flipped around.

Found the problem. The connector was not plugged into the sensor. I likely forgot to securely connect it.
