Important Notes


Analog Sensor 0V Reference (Pin B10)

This pin should be connected directly to the 0V (Ground) pin on any low current analog sensor, for example Pressure or Temperature.

  • DO NOT connect the ECU pin B10 directly to the Engine Block or ECU Ground. These are dedicated and specialised ground outputs for all analog channels and should be connected directly to the sensor.
  • DO NOT connect frequency-based sensors to these pins; for example, an Ethanol content sensor. The sensor 0V pin should be connected to the ECU ground. 



Half Bridge Driver Power Supply Input (Pin A34)

Pin A34 is a dedicated power supply for Auxiliary Channels 9-10. Power must be supplied to this pin for these channels to operate correctly. In non-DBW (Drive by Wire) applications the ECU Supply power can be shared, assuming the wire gauge has a sufficient rating for the current demand. In DBW applications power to this pin MUST come from an ECU controlled DBW Relay.
