Gauge Installation
2. Connect the boost line to the gauge using the female
compression fitting. Once this is connected, run the boost
line through the firewall and to your intake manifold.

Note: Make sure the boost line is not pinched; the
use of a rubber grommet through the firewall is
required.
3. Drill and tap your intake manifold to 1/8-27 NPT. Next,
connect the included male compression fitting, which is
attached to the boost line, to the tapped 1/8-27 NPT hole
you just drilled in your intake manifold.

Note: After drilling and tapping your intake
manifold, be sure to use vacuum and pen magnet to
safely remove all shavings from the manifold. You
may also remove the top of your intake manifold
before drilling for extra protection against drill
shavings.

Note: If you are installing this gauge into a Dodge
Ram, model years 98 to 07.5, you can install a boost
bolt directly to your intake manifold. Installing this
boost bolt does not require any drilling or tapping
and can be purchased at www.GlowShift.com
Connecting the Power Wire Harness
4. 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.
5. 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.
6. 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.
7. 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.
8. Reconnect the vehicle's negative battery cable.

Power on the vehicle to ensure the gauge is
functioning properly.
