Fuel Gauge Test - Intellitronix DP3001 Installation Manual

Turn Signals - Grey Two 18-gauge wires, one for each signal. Each wire is labeled on the printed
circuit board as 'LEFT' and 'RIGHT'. Connect each wire to its corresponding indicator circuit.
OR
Right Turn Signals - Grey with White strip 18-gauge wire is the - RIGHT turn signal
Left Turn Signals - Grey with Black strip 18-gauge wire is the – Left turn signal.
Each wire is also labeled on the printed circuit board as 'LEFT' or 'RIGHT'. Connect each wire to its
corresponding indicator circuit.
ater – Blue - This gauge is incompatible with other sending units, so you must replace the existing
W
water temperature sending unit with the included sender. Do not use Teflon tape or other sealer
on the new sending unit's threads to avoid inaccurate readings. Connect the blue wire to the
sending unit. For best results we suggest running a new wire.
Oil Pressure - Orange - Connect to the Factory sending unit. We have calibrated this gauge to
work with an AC Delco Sending unit. For best results we suggest running a new wire.
Voltage Gauge – This Gauge Requires no wire hookup. Volt Gauge is built into the
dash panel and is powered by the main power and ground connection of the dash. It
does have an Adjuster to fine tune the voltage. Note: you will need to adjust it before
fully installing the dash
Fuel – Yellow The fuel gauge sending unit is not normally supplied because the display system
can use the existing fuel level sending unit in the tank in most cases. If your wiring harness
already has a single wire routed through the vehicle for the fuel sender, then it may be used. If
using a wire from an external harness, make sure that the wire does not have power. Fuel senders
reference their ground from the sender mounting plate. Connect the yellow wire to the factory
sending unit. We suggest RUNNING Two new wires to ensure the best connection. GROUND
the Fuel sender to ENGINE BLOCK with rest of Dash Grounds. Then Install a NEW sender wire
to ensure proper OHMS are received by Fuel Gauge.
Note: The default setting for this dash is the GM industry standard of 0-90Ω

FUEL GAUGE TEST

The most common problem with our Fuel Gauge not working is the circuit is not complete. The
easiest way to test for this is to use a voltmeter and test for continuity on wires going to fuel
sender after disconnecting from gauge. If not disconnected it will give you a false reading. With
wire disconnected from Fuel Gauge check for continuity to ground. Then test for OHMS to verify
within range of fuel sender. If you don't have an accurate reading. Run a new ground wire to
engine without this the Gauge will not work properly
Note: If doing a LS engine swap, pick up the tach signal wire from the ECM/ECU and then set
the tach switch to 4-cylinders. You may also need to order the Intellitronix LS Engine Swap
Adapter Kit for Series 1, 2 and 3 engines. The part number is 8014LS. If you are getting the tach
signal from the ECU, the resistor in the adapter kit will help pull a stronger signal for the
tachometer. If your engine is a LS the Tachometer will need to be put into 4 cylinder mode by
removing Resistors if the Tachometer does not have a push button for programing, please call
Tech Support at Intellitronix, as you may need to send the gauge back to us to be reconfigured.
There is no charge for this additional service.
