For Product Numbers: GS-ET15 & GS-EWT15
Wire Harness Color Code
Red: 12v Constant (un-switched) Source (+) Black: Vehicle / Engine Ground (-)
White: 12v Ignition (switched) Source (+) Orange: 12v Dimmer (switched) Source (+) (optional)
1. Disconnect the negative battery cable.
2. Connect the white sensor wire to the back of the gauge (port D) and
run it through the firewall to the vehicle’s fuel level sensor.

Note: Be sure to use a grommet when routing the wires
through the firewall to protect them from stripping and
damage.
3. Use the Fuel Level Sensor Sensitivity Switch on the back of the gauge
to set the correct ohm (Ω) value scale to match the rating of the vehicle’s
fuel level sensor. Use the chart below to reference the correct setting that
applies closest to the values of your sensor. Please verify settings with a
repair manual or a dealer before installation.

If you need to change the ohm selection, you must remove
power from the gauge, make your selection, and then reapply
power to the gauge for proper calibration.

Be sure that your factory fuel level sensor is properly
grounded. You may have to add a secondary ground to
ensure it is properly grounded.

4. Connect the white 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 switch of the vehicle.

Note: 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 “expandable 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
GlowShift.com or a local auto parts store.
5. Connect the
red wire to a positive 12 volt constant (un-switched)
source, either directly to the battery or to a fuse panel on the vehicle.

Note: 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 “expandable 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
GlowShift.com or a local auto parts store.
6. 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.
7. 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.
9. Daisy Chain Feature (Optional): If you are installing more than one
Elite 10 Color Gauge, you can use the daisy chain feature to power up to 4
additional gauges. Simply plug the included daisy chain wire into the
gauge that is already powered (port B); then plug the other end of the wire
into the daisy chain port on the next gauge.
