out-of-range error from the sensor or sensor wire. If "OIL FAIL HIGH" is shown this indicates
that the Control Box is sensing an open circuit or out-of-range error from the sensor. If either
indication remains on the display, inspect the sensor wire for damage, check the routing of the
sensor wire, check the sending unit grounding, and check that the correct sending unit is
connected.
PRESSURE INPUT - GND
• This is the ground reference used for three-wire pressure sensor. This will connect to the
black wire from the Dakota Digital SEN-03-10.
***DO NOT connect this terminal to any other devices
PRESSURE INPUT - DRN
• This is the cable shield for three-wire pressure sensor. This will connect to the bare silver
shield wire from the Dakota Digital SEN-03-10.
***DO NOT connect this terminal to any other devices
FUEL INPUT - SIG
• The fuel gauge sending unit is not normally supplied because the Instrument Cluster can use
the existing resistive fuel sending unit that is already in the tank in many cases. Most OEM
and aftermarket fuel sending units are compatible with this system. It is also possible to
manually program a setting for sensors that are not pre-programmed into the system.
• Dakota Digital recommends that you run two wires back to the fuel level sensor to insure
proper grounds. Use the FUEL INPUT - GND and FUEL INPUT - SIG terminals and run a
twisted pair of wires back to your fuel level sensor. Connect the GND terminal to the fuel
level sensor body or a mounting screw to ensure the sensor is sufficiently grounded. The
other wire is the sensor signal which goes to the SIG terminal.
• If your wiring harness already has a single wire routed through the vehicle for the fuel sensor
then it may be used. If using a wire from an existing harness, make sure that the wire does
not have power. Fuel sensors reference their ground from the sensor mounting plate. Make
sure that a ground wire is connected from one of the sensor's mounting bolts to the vehicle
frame.
• The fuel sensor type is selected using the fuel setup menu under "INPUT". The settings are
discussed later in the setup section. Anytime the fuel level is below 10% a red warning light
will turn on.
• The MESSAGE AREA on the GRAFIX Instrument Cluster will display "PLEASE CALIBRATE
FUEL" until the fuel sensor type has been set. If the message display shows "FUEL
SHORTED" this indicates that the Control Box is sensing a short to ground or out-of-range
error from the sensor or sensor wire. If the message display shows "FUEL OPEN" this
indicates that the Control Box is sensing an open circuit or out-of-range error from the sensor.
If either indication remains on the display, inspect the sensor wire for damage, check the
routing of the sensor wire, check the sending unit grounding, and check that the sensor
selection is set correctly for the sending unit that is connected.
FUEL INPUT - GND
• This terminal is used to provide a ground connection for the fuel level sensor. Dakota Digital
recommends that you use the FUEL INPUT - GND terminal and run a twisted pair of wires
back to your fuel level sensor. Connect the GND terminal to the fuel level sensor body or a
mounting screw to insure the sensor is sufficiently grounded. One terminal on the sensor is
the signal which goes to the FUEL INPUT - SIG terminal.
***For fuel level sensors that are attached to an electric fuel pump, or if you have an
electric fuel pump in the tank, make sure that the fuel pump is externally grounded to
the vehicle chassis. Attempting to ground the fuel pump to the Dakota Digital Control
Box will result in erratic operation and damage to the Control Box.
