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.
Note: For an easier installation GlowShift offers an extended wire harness
that offers 9 feet of sensor wire and 3 feet of power wire so there is no need to
extend the wires yourself.
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.
