(Figure 1, Rear View of M-300TE)
1. Connects to 12V-18V power source.
2. Analog outputs (0-5V linear wideband output, 0-1V narrowband output, ground)
3. Termination jumper. Closed for first SM in iMFD daisy chain.
4. Connects to next SM in iMFD daisy chain or to first DM
5. Connects to previous SM or unconnected if first SM in iMFD daisy chain
6. Connects to O2 Sensor Harness then to Bosch sensor.
Install the Wideband Sensor:
1. Mount the wideband oxygen sensor before the catalytic converter and at least 24 inches downstream from your engine
block or turbo for optimal performance. The sensor element will fail if it is exposed to exhaust gas temperatures above 1562
deg Fahrenheit (850 deg Celsius). If you plan to replace your stock narrowband oxygen sensor with the PLX wideband,
please read PLXApp004 online for more information. The sensor will directly screw into an 18mm X 1.5mm pitch sensor
bung. The bung is available from the PLX Online Store.
2. You will hear a "click" when the connectors are properly mated.

3. Connect the wire harness to the Sensor Module device by mating it with the M-300TE box indicated by “O2 Sensor”
