1. Disconnect the negative battery cable.
2. Install and connect the 1/8
th NPT fuel pressure sensor to your
vehicle’s fuel system. We recommend installing the sensor to
your fuel filter housing or lift pump.

Note: When connecting this sensor to a Cummins Diesel
engine (usually at the lift pump), we require installing a
snubber valve. This eliminates harmful fuel pressure
spikes that may result in the failure of the sending unit.
This can be purchased at GlowShift.com

Note: Some vehicles may require additional adapters or
a sensor relocation kit to complete the installation of this
sensor.
3. Route the pressure sensor wire harness from the back of the
gauge (port D) through the firewall to the engine bay. Next,
couple and secure the sensor wire harness to the back of the fuel
pressure sensor.

Note: Be sure to use a grommet when routing wires
through the firewall to protect them from stripping and
damage.
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.
