Temperature Sensor Installation
2. There are two common types of transmission temperature
sensor installations:
 Transmission Test Port: Most vehicle transmissions
come equipped with a test port location. This may be
located on either the driver or passenger sides of the
transmission near the transmission oil pan. The bolt
in this port should be removed and the sensor fitted in
its place. Confirm port and thread size with your
vehicle dealer or owner’s manual. A test port
extender will be required when installing this sensor
into Dodge Ram model years 94-07.5
 Stock Sensor Location: Use a T-fitting (optional) to
T off your stock sensor location. This will allow you
to keep your stock sensor installed, while also
allowing you to install an aftermarket temperature
sensor.
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. Connect the green wire from the gauge to the white wire
of the transmission temperature sensor. Then, connect the
black wire of the transmission temperature sensor to any
good (unpainted) ground connection.
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.
