I’ve changed the cluster on my 95, the fuel and volt guage work, but not the speedo or oil temp and pressure, tachometer is moving but doesn’t go over 1000rpm. I saw on YouTube an adjustment screw for the tachometer but my one does not have it

 

Is the cluster you have from a truck with the same engine? V6 tach and 4 cylider tach have different clocking.

Oil temp and pressure require the proper sending units.

The speedo not working? Not sure on the '95, but mine is a mechanical speedo. If you have a cable and housing that run from the back of the trans to the speedo yours is too. If that is the case, the cable isn't seated porpoerly in the drive recepticle, either end or both.
If the speedo is electronic, did the cluster come from a truck with an electronic speedo?

Compatibility baby!
