Connecting the Power Wire Harness
2. 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.
3. Run the green wire from the back of the gauge, through the
firewall to the location of the speedometer signal wire. Cut or
splice the wire so that the speedometer signal wire can be
connected inline to receive the speed signal. Make sure all
connections are covered, fastened and sealed correctly to ensure
proper operation and accuracy.

Note: Be sure to use a grommet when routing wires
through the firewall to protect them from stripping and
damage.

Note: If your vehicle has a speed driven speedometer
cable an electronic speed sensor is required.
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. Speed Range Selection:

Adjust the dial switch on the back of the gauge to an
approximate range.

Move the switch from 0,9,8,7,6,5,4,3,2,1 to
narrow the speed range.

Move the switch from 1,2,3,4,5,6,7,8,9,0 to
widen the speed range.

Once you have an approximate setting, fine tune the
gauge by using the adjustment knob on the back of the
gauge. Turn the knob to pinpoint the exact MPH by
using your stock gauge. If you cannot get the MPH
correct you will have to adjust the switch.

To ensure proper calibration of the speed range selection,
remove power from the gauge, change the selection
setting, and reapply power to the gauge.
9. 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.
10. To switch between the two resettable trip meters, press the
button on the front of the gauge. To clear either one of the trip
meters, select either trip A or B then press and hold the set button.
