Thanks for the response, but unfortunately, it isn't the red wire. I have even removed it from the wiring block and run a new wire from there all the way down. Is there a ground strap or wire from the cluster to the body that could have come loose? The cluster has never been out of the car. The wiring is in good condition with the exception of the oil sending wire, which still functions correctly. This is a very clean car, including under the hood, with only 123K on it. I know this is something very simple, just a matter of finding it.
