Pressure Sensor Installation
2. Install the included sensors to the sources that you are monitoring.

Note: Each sensor features 1/8 th NPT threads. A thread
adapter may be required when installing each sensor to your
air pressure source.

Note: Be sure to use Teflon tape on all the sensor threads.
3. Sensor 1 Connection: Using automotive grade wiring (18 gauge);
connect the green wire on the back of the gauge to the G post on the
sensor, and connect the black wire to the M post of the sensor.
4. Sensor 2 Connection: Using automotive grade wiring (18 gauge);
connect the blue wire on the back of the gauge to the G post on the sensor,
and connect the black wire to the M post of the sensor.
Connecting the Power Wire Harness
5. To make the wiring of your gauges easier you can purchase an
expandable circuit. This component easily fits into your fuse panel and
provides an additional fused power wire for accessories such as gauges.
The expandable circuit is available for purchase at www.GlowShift.com.
6. Using automotive grade wiring (18 gauge); connect the red wire to a
positive 12 volt ignition (switched) source. It may be connected to the fuse
panel, an accessory wire, or any positive 12 volt source that turns on and
off with the ignition.
7. Using automotive grade wiring (18 gauge); connect the red wire to a
positive 12 volt ignition (switched) source. It may be connected to the
fuse panel, an accessory wire, or any positive 12 volt source that turns on
and off with the ignition.
8. Using automotive grade wiring (18 gauge); connect the black wire to
any good (unpainted) ground connection. You may also route a wire
directly to the negative side of the vehicle’s battery.
9. The Night Time Dimming feature decreases the brightness of the
gauge face by 30%. Connect the orange wire to the 12 volt positive
headlamp source. This allows the mode to be activated when the
headlights come on. This step is optional and will not affect operation of
the gauge if it is omitted.

Note: Do not connect the orange wire to a dimmer wheel. This
will cause the gauge lighting to flicker.
10. Reconnect the vehicle's negative battery cable.

If your gauge(s) do not illuminate or do not recall your last
saved color, your switched and un-switched sources are
reversed.

If your gauge(s) only illuminate red then the yellow wire for
constant source is not connected properly.

Be sure all of your wiring is correct to ensure proper gauge
operation.
