Wiring
Both of the exhaust gas temperature gauge and sensor
must be connected to the vehicle’s ground (chassis or earth).
Soldering or crimp on electrical connectors must be used on all electrical connections.
Unused wires must be insulated with electrical tape in order to prevent unwanted electrical connections.
Follow safe electrical operating practice.
Refer to the table and diagrams below for further details

Operation & Troubleshooting
Once the electrical connections and EGT sensor installation are completed, turn the
car key to “on” position. The EGT gauge
will illuminate and the needle will be positioned at a temperature reading.
Start the car and check for any exhaust leaks.
The needle position will change relative to the exhaust gas temperature. If the needle does not move relative to the exhaust
gas temperature, ensure that all electrical connections are correct and that the EGT sensor is installed correctly as per
instructions above.
Monitor the gauge reading against the operating conditions of the engine. The temperature should be at a minimum during
cold start then slowly increase and remain at a normal operating temperature.
If the display does not illuminate, ensure that the gauge electrical connections are correct.
If the display illumination/operation is not switched with ignition, ensure that the red wire is connected to an ignition switched
source not a co12VDC source.
If the display needle is erratic, ensure that all electrical connections to the EGT sensor are correct.
