I don't know if this helps anything, but it might?
When I swapped the non-tach cluster for a tach one in my 94, I swapped over the odometer (nothing broke!). When I subsequently took the truck for a test drive with the new cluster, the odometer didn't work, and I didn't understand why. So I took the cluster out and opened it up to investigate.
The problem? I forgot to reconnect the motor
