You would use the ANA Vx Connections on the Auxiliary connector for spare sensors.


For a voltage based sensor (for example a MAP sensor) 5V and GND are also on the AUX connector to power the sensor. You can then just connect the signal wire from the sensor to your chosen ANA Vx pin on the Aux Plug  and configure as per here.


You can find out the pin-out of the AUX connector on your Plug-In ECU at the end of the Install guide for your model, which you can select from here.


A example of this is below: Note you will need to check the pin-out of your pressure sensor (and making sure it is a 0-5v output) and then assign it, and finally calibrate it according to its data-sheet in MEITE. In the diagram below, we take 5V, Ground and feed the signal back into ANA V5. Typically, 22AWG wire is used.


The connector body is MOLEX 39-01-2205 and the pins are MOLEX Mini Fit Jr. All available from mouser.co.uk.



If you are instead using a thermistor based sensor (resistance changes with temperature, like an oil temperature sensor), then you can still use one of the ANA-Vx inputs, only you will also need to add a pull-up resistor. The Ana-Vx section of the manual here details this. 5V REF and Ground can be obtained from the AUX connector as per above.
