INSTALLATION INSTRUCTIONS

2650-1481-00rA

CAUTION!

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).

Installation

1. Check that you have all parts required for installation, and the engine

is cool.

2. Disconnect the negative (-) battery cable.

brackets and nuts to secure gauge to dash or panel, if a friction fit or a

pod mounted bracket are not used.

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).

NOTE: When the ignition is off the pointer may not always

rest at zero.

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’ 

wire from the gauge harness, and the VIOLET/RED wire needs to be

connected to the 8’ BLACK wire from the gauge harness.

Recommended Splice

1. Carefully strip approximately 1/2" of the insulation from the OEM wire.

2. Wrap the bare end of the gauge harness wire around the bare OEM wire.

3. Solder connection. (see figure 3)

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