Earth
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.

Overview
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
Indicators Bulbs are this kind. For more details, see Bulbs
Old VS New Styles
* Original Style: Labels written next to lamps * New Style: Labels written on lamps, double-line Temp Gauge
Old Style: warning lamps have no labels (labels are on the mask plate):
New Style: larger warning lamps, with the labels on the lenses
New Style can be ID'd by the doubled temperature lines
Original Style with single temperature lines
Variations
- North American Market: has extra warning lamp marked BRAKE (see details below)
- non-USA, one lamp shadow is unlabeled
- 1975-up ute with larger warning lamps
Japan market: no label on the mask for BRAKE
Late Ute: New larger warning lamps, with the labels on the lense
Also has BRAKE lamp
Non-USA: No BRAKE lamp

Facelift
Plastic anti-glare covers instead of flat glass.
Facelift gauges use the new font and anti-glare covers

Clock with Cover
This cover (source unknown) does not fit the tachometer
Tachometer using flat-plastic cover also fits the cluster lid
Gauges have long-reach brackets, and indicator lamps are moved to the Cluster Lid
Note high-mounted indicator lamps

Brake Lamp
A brake "warning" lamp was added October 1975. Prior to this the cluster gauge had a blank spot. The brake lamp was fitted to all 1970-1973 North America 1200s per US federal law.
It was used for:
* "Hand Brake is on" reminder (North America and Japan) * Brake pressure warning switch (North America)

1972 USA Owners manual (Page 11 ... ):
BRAKE SYSTEM WARNING LAMPIf 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.

Datsun 620 pickup uses a 1200-sourced cluster gauge. It used plastic spacers to set back from the cluster lid as the 620 had a slanted instrument panel.
