The ME range of ECUs are designed to use the Bosch Wideband Knock Sensor as per one we list on our website. It is essentially a microphone that the ECU is tuned to listen for the "pinging" sound when knock occurs. This is done via the Knock Settings on the ECU.


The sensor should be bolted to the engine block. Most engines have an OEM mounting point for the knock sensor.


They have 2 pins, and use a standard mini-timer type connector. Simply wire the sensor Pin 1 (left most pin in the below picture) to the Knock +Ve/Knock Signal Pin and the other Pin to Ground (Sensor ground preferred, such as the Ground available on the Auxiliary plug on Plug-In systems.)


Shielded twin core cable should be used, with the shield being connected to the chassis of the car.
