Check the ground wire for the tail light harness. Usually bolted to floor pan of trunk underneath the mat. It could be off or just plain rotten.
On stick cars you can get feed back to the ignition switch, dash lighting, etc.....tach even quits working..

If this should be your problem you can ask me about the time I went to cut my car off and the engine wouldn't quit running. Stick car with factory reverse column lock. Brake light power feeding back through back-up light wires. And had the same dash problems this car is having.

I'll check that tonight, I have a couple hours to work on the car. I did put a multi meter on the gauge cluster housing and I am reading 11.74 volts. That's with the key off.

I am also going to pull the cluster back out and remove the clock hot wire out of the harness and try again. That is the only wire that has power when the key is off. If that doesn't do it then it's backfeeding from somewhere else.
