Tinted Series - Volt / Air Fuel Combo Gauge
For Product Number: GS-TC01
Wire Color Code
Black: Vehicle Ground (-) Gray: NARROWBAND Oxygen Sensor Signal
Red: 12v Ignition Source (+) (switched)
Yellow: 12v Constant Source (+)(un-switched)
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. Using automotive grade wiring (18 gauge), connect
the yellow wire to a positive 12 volt constant (un-
switched) source either directly to the battery or to a
fuse panel on the vehicle. If wiring to an un-fused
source, install a 3 amp fuse inline within 20 inches of
the sources connection.
4. Air / Fuel Ratio: Connect the gray 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 gray wire on the Oxygen Sensor. (0v ~ 1v Output -
NARROW BAND SIGNAL ONLY)
5. Volt Meter: The volt meter will obtain and monitor voltage of
the vehicle through the red wire / switched ignition source.
7. 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.
8. Reconnect the negative battery cable.

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.
