1. Disconnect the vehicle's negative battery cable.
Pressure Sensor Installation
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: This gauge and sensor are not recommended for
use on vehicles with returnless fuel systems.
 Note: Some vehicles may require additional adapters to
complete the installation of this sensor.
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. Once the sensor is installed, connect the wire harness to the
lower port on the back of the gauge and route it to the fuel pressure
sensor location.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
