1. Disconnect the negative battery cable.
2. There are two common types of transmission temperature sender unit
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.
3. Route the temperature sensor wire harness from the back of the
gauge (slot #2) through the firewall, engine bay and to the sensor. Next,
couple and secure the sensor wire harness to the temperature sensor.
Connect the white wire on the temperature sensor to the white wire on
the harness, and then connect the black wire on the temperature sensor
to the black wire on the harness.

Be sure to use a grommet when routing wires through the
firewall to protect them from stripping and damage.
4. Connect the white 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 switch of the vehicle.
5. Connect the
red wire to a positive 12 volt constant (un-switched) source,
either directly to the battery or to a fuse panel on the vehicle.

If wiring to an un-fused source, install a 3 amp fuse inline within 20
inches of the sources connection. You may obtain an optional
“expandable circuit” accessory. This component easily fits into
your fuse panel and provides an additional fused power wire for
accessories such as gauges. This is available at www.MaxTow.com
or a local auto parts store.
6. 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.
7. Connect the black wire from the gauge, to any good (unpainted) ground
connection. You may also route a wire directly to the negative side of the
vehicle’s battery.
8. Reconnect the negative battery cable.
