Gauge Installation:
2. This gauge has a standard 1/8
th
NPT port for monitoring
pressures up to, but not exceeding 200PSI. Run an airline
from a compressor, air tank or pressurized system or device
to the installation location of the gauge. Connection sizes
may vary from device to device. Also, if more than one
component is going to be monitored then additional gauges
may be necessary. Check your device’s instruction manual
for proper pressure monitoring devices, connection
instructions and sizes as well as operation.
Connecting the Power Wire Harness
3. 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.
4. Using automotive grade wiring (18 gauge), connect the
yellow wire to a positive 12 volt constant (un-switched)
source either on the vehicle or in the fuse box.

Note: If you are connecting the yellow wire
directly to the battery, you MUST install a 3 amp
fuse within 6-8 inches of the battery connection.
5. 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.
6. 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.
7. 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.
8. 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.
