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.
