Fox Body Mustang Tachometer Replacement

10. There are two plugs behind the cluster for the tach and secondary gauges. Once these are unplugged, the cluster can be taken out of the car. The remainder of the work can take place on a workbench.

11. Removal of the clear plastic lens and the bezel trim panel is achieved by taking out the screws holding it in place.

12. Ten screws hold the lens and gauge-bezel trim panel in place. Once removed, the lens lifts off the cluster, followed immediately ...

13. ... by the bezel trim panel. Some of the screws that hold the trim panel in place don't go through the clear lens. Removal of the trim panel gains access to the actual gauge faces.

14. Once you have access to the gauges, swapping the old tachometer for the new one is easy. The lenses for the center indicator lights come off with the bezel trim panel, so there's easy access to the tachometer. By carefully pulling on the face, the tach is readily removed from the gauge cluster. Note that the edge of the tach face goes under the face of the water-temperature and volt gauges.

15. Here's the used tach from Midwest Mustang ready to install onto the gauge cluster. Notice the three prongs on the back of the tach's printed circuit board; they fit into the three plugs in the white center area of the gauge cluster. It's a press-fit installation and takes minimal effort to plug the tach into place.

16. With the tach in place, the gauge-bezel trim panel can be reinstalled, followed by the lens.

17. Once the lens is inserted, the cluster can be reinstalled in the car. This includes the plugs in the back of the cluster, reconnecting the speedometer cable, bolting the cluster back in place, and putting back the trim and electrical items. This is an excellent repair/upgrade, and you'll enjoy having a working factory tach once again in your '87-'93 Fox-body Mustang.
