Gauge Installation
2. Air / Fuel Ratio: Connect the green wire to the vehicle oxygen
sensor signal, before the catalytic convertor. You may connect this
wire directly to the ECU harness or splice into the signal wire
leaving the sensor. This wire color can vary, be sure to consult your
vehicle’s owner’s manual. (0v ~ 1v Output - NARROW BAND
ONLY)
Note: If your vehicle does not have a narrowband o2 sensor, you
will have to purchase a single wire narrowband o2 sensor to
complete this installation.
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.
