INSTALLATION
1. Disconnect the negative battery cable.
2. Secure the gauge in a 2 1/16
th
” (52MM) mounting hole with the supplied bracket.
3. Plug the 8-wire power harness into the mating connector on the back of the
gauge and connect the wires as shown in Figure 1. Note: the locating tabs on
the side of the connector should be nearest the center of the gauge.
4. Using the supplied hose adapter, boost tee, vacuum hose, and zip ties, connect
the sensor to a good engine manifold pressure source, downstream of the
throttle body.
5. Connect the sensor to the gauge using the 3-wire sensor cable. The single-row
connector connects to the back of the gauge. The locating tabs on the single-
row connector should be nearest the center of the gauge.
RED - Connect BOTH RED wires to a constant 12 volt power source utilizing a 5A fuse.
BLACK – Connect BOTH BLACK wires to a clean power ground.
PINK – Connect to a switched 12 volt power source that is on in the On, Run, and
Crank key positions utilizing a 5A fuse. NOTE: The gauge can be used to help verify a
power source that is on in the On, Run, and Crank key positions. With the sensor
disconnected, turn the key to the On position. The needle will sweep counter-clockwise
against the needle stop then sweep clockwise to the vertical position, pointing down, the
left status light will flash. Move the key to the Run position, then the Crank position.
The needle should remain pointing down, and the status light should continue to flash.
If at any time the needle sweeps counter clockwise, or the status light remains off, the
power source has turned off and is not suitable for use.
GREY - Connect to instrument lighting circuit supply voltage.
*WHITE - Connect to Analog + Input.
*BROWN - Connect to Analog – input. (Must be connected if Analog + is used)
*optional – only needed if using the available differential analog output
Wiring notes:
RED - When wired as shown above, the gauge will park the needle against the
needle stop upon powering down. Alternatively, both RED wires can be connected to
the same location as the PINK wire. With both RED wires and the PINK wire connected
to the same switched power, the needle will remain at its current position upon powering
down. For both power connection methods, the needle will rotate to the parked position
before rotating to the value of the current operating condition upon powering up.
GREY – The GREY wire is used to control the lighting intensity of the gauge.
Maximum lighting intensity is achieved when the GREY wire is connected to 12 volts.
Minimum lighting intensity is achieved when the GREY wire is not connected. The
instrumentation illumination on many vehicles is controlled by varying the supply voltage
to the instrument panel lights. When the GREY wire is connected to the instrument
panel supply voltage, the intensity of the gauge is controlled by the dimmer switch on
the dash.
