The cluster gauge is the combination meter in the dashboard, consisting of the Speedometer, Fuel Gauge, Temperature Gauge and the dash lamps including Turn Signals.



The cluster lid is the facia plate that hold the gauges and switches.

Technically, the combo meter is the "cluster gauge", but in practice the entire unit including the speedometer is called the "cluster".

Cluster gauge has these components:

* Temperature Gauge
* Fuel Gauge
* Cluster Lid Shadow Mask, which has these lamp masks:
  * OIL (red warning)
  * BEAM (blue indicator)
  * CHG (red warning)
  * BRAKE (red warning) [on USA 1200s and newer utes, blank on others]
* 25014-H18000 ASS'Y-PLATE-shadow

The gauge is earthed (grounded) by the large tab at the bottom. This means the gauges won't work properly until bolted in place. For testing, an earth wire can be attached.

1972 USA Owners manual (Page 11 ... ):

If either half of the dual brake system fails, the brake warning light (BRAKE) glows when brakes are applied. You must stop the car immediately and if you can safely operate with two-wheel brakes, move your car at reduced speed to the nearest service station.

This warning light is also used as the parking brake warning light.

Before starting, if the warning light does not glow when the parking brake and ignition switch are on, have the electrical system checked.
