1. Disconnect the negative battery cable.
2. Using automotive grade wiring (18 gauge), connect
the red wire from the gauge 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 switch of
the vehicle.

If wiring to an un-fused source, install a 3 amp
fuse inline within 20 inches of the sources
connection. You may obtain an optional “add a
circuit” accessory. This component easily fits
into your fuse panel and provides an additional
fused power wire for accessories such as
gauges. This is available at
www.GlowShift.com or a local auto parts store.
3. (Optional) The dimming feature of the Tinted Series
decreases the brightness of the lighted gauge face by
30%. Connect the orange wire to a positive 12 volt
switched source. The most common installation is to
splice and connect to the 12 volt positive headlight
source. This step is completely optional.

This gauge should never be connected to a dimmer.
Connecting the gauge to any type of dimmer switch
unit will cause the gauge to improperly function.
4. Air / Fuel Ratio: Connect the green wire to the vehicle
Oxygen sensor signal. You may connect directly to the ECU
harness or splice into the signal wire leaving the sensor. This is
usually the green wire on the Oxygen Sensor.
(0v ~ 1v Output - NARROW BAND SIGNAL ONLY)
5. Using automotive grade wiring (18 gauge), connect the
black wire from the gauge to any good (unpainted) ground
connection. You may also route a wire directly to the negative
side of the vehicle’s battery.
6. Reconnect the negative battery cable.

Be sure all of your wiring is correct for proper gauge
operation.

This gauge should never be connected to a dimmer.
Connecting the gauge to any type of dimmer switch unit will
cause the gauge to improperly function.
