Installing the EGT Probe
2. There are two common types of EGT probe installations. We
recommend installing the probe pre-turbo for the most accurate
reading.

Exhaust Manifold: Drill and tap the exhaust manifold to 1/8
th
-
27 NPT. Install the supplied EGT probe directly into your
exhaust manifold.
Note: After drilling and tapping your exhaust manifold be sure
to use both a magnet and vacuum to safely remove all shavings
from the manifold.

Exhaust Temperature Bracket: This method is not shown, but
you may purchase an exhaust temperature bracket from
www.GlowShift.com. This adapter is clamped and tightened
around the exhaust pipe and provides a 1/8
th NPT fitting for an
EGT probe. Using a 3/16 th drill bit, drill a hole in your exhaust
pipe. Position and tighten the adapter clamp, then permanently
mount the probe through the fitting and into the exhaust pipe.
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. Connect the pink & blue wires from the gauge wire harness to the
pink & blue wires of the exhaust temperature probe.
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.
