At first the odometer and trip meter stopped and the tachometer and speedometer were working. Removed the unit and replace the small worm gear on the odometer. Reinstalled and now nothing works. Checked the fuses are okay. This is analog with three connectors on the unit. The dash lights still work but that is it. I cannot find a wiring diagram for the three plug connectors. Could it be in the circuit board or the connectors not receiving power?

Hello,

It sounds like you popped a fuse #2, 29 or 19 of the cluster has gone bad in which case you will need to install a rebuilt or used unit. Here is the wiring diagrams for the cluster and the fuse locations with guides so you can check it out.

This video is the job being done but on a similar car.
