for wire color by
application chart.
As a safety precaution, the
+12V terminal of this product
should be fused before
connecting to the 12V ignition
switch. We recommend using
a 1 Amp, 3AG fast-acting type
cartridge fuse (Littlefuse® #
312 001 or an equivalent).

Recommended Splice
1. Carefully strip approximately 1/2" of the insulation from the OEM wire.
Use caution not to cut or break wire while removing the insulation. (see
figure 1.)
2. Wrap the bare end of the gauge harness wire around the bare OEM wire.
(see figure 2)
3. Solder connection. (see figure 3)

4. Wrap splice with electrical tape to seal and insulate connection. (see

Installation
1. Check that you have all parts required for installation, and the engine
is cool.
2. Disconnect the negative (-) battery cable.
3. Gauge mounts in a 2-1⁄16” hole for 2-1⁄16” gauge. Use supplied
brackets and nuts to secure gauge to dash or panel, if a friction fit or a
pod mounted bracket are not used.
4. Drill 1” diameter hole where wires pass through sheet metal (such as
firewall) and install rubber grommet provided. (Grommet will require
slit). Route the necessary wire through the grommet into the engine
compartment. The 8’ Purple and 8’ Black wires will need to be routed
to the engine compartment.
5. Connect the white wire to dash lighting or switchable 12v light source,
the 4’ red wire to a switched +12V source and the 4’ black wire to
ground (see diagram for details).
6. From the table below, determine the wire colors used in your vehicle for
the signal and ground wires.
7. Locate the harness connected to the sensor (Fuel Rail Pressure or HPOP)
in your vehicle. Confirm the harness matches the wires identified in the
table.
8. Connect the 8’ Purple wire from the gauge harness to the signal wire.
9. Connect the 8’ Black wire from the gauge harness to the sensor ground.
10.Secure all wiring with cable ties (not included) to ensure they are kept away from moving parts, sharp edges, and high heat sources.
11.Reconnect negative (-) battery cable.
For example: The 2004 Dodge with a Cummins 5.9L uses a BROWN/
YELLOW wire for Signal and a VIOLET/RED wire for Ground. The
BROWN/YELLOW wire needs to be connected to the 8’ Purple
wire from the gauge harness, and the VIOLET/RED wire needs to be
connected to the 8’ BLACK wire from the gauge harness.
CAUTION: If you will be working with the fuel system, take
NOTE: It is recommended that the electrical connections made
in the engine compartment be soldered, and wrapped with
several layers of a good electrical tape.

Power-Up
The pointer will move backward to the stop pin and then move to the zero box, or current pressure reading. This
procedure is an auto-calibration function and is performed on every power-up. While this test is being performed, the
gauge may make a clicking sound. This is normal.
