This applies to all standalone 2-1/16” gauges with a 0-5 or .5-4.5V input (transducer). The
instrument will have BOTH a 4 and a 3 pin plug. The 3 pin plug will power your transducer.
Please refer to the chart below for input DIP switch settings required for your application.
Transducers operate on .5-4.5V range. AFR and 0-5V output devices use 0-5V. The input
for both ranges should be on the BLUE wire on the 3-pin harness. The GREEN wire on the
4-pin harness is not used.

FUEL GAUGE:
All fuel gauges are programmable by the DIP switches on the driver gauge or the 2-1/16”
gauge itself. All fuel gauges and ranges are identical on all instruments. Set the switches
as shown in the chart below for your application.
2-1/16” ANALOG MINOR GAUGES
This applies to all standalone 2-1/16” gauges. Driven instruments are adjustable at the
master gauge on the back under the plug. On the back of the 2-1/16”gauge the switches
are visible without removing any covers/plugs.
Analog instruments refer to fuel, temperature, volts and pressure that use a traditional
resistance to ground sender (not a transducer). All gauges are set at the factory to match
the gauge dial range. The only time the end user will need to change the settings is for the
fuel range. Use the settings below as a reference if needed.
2-1/16” 0-5V INPUT MINOR GAUGES
This applies to all standalone 2-1/16” gauges with a 0-5 or .5-4.5V input (transducer). The
instrument will have BOTH a 4 and a 3 pin plug. The 3 pin plug will power your transducer.
