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.

Pin B2 (5V Supply) is a branched connection feeding the engine sensor 5V supply.
3.4 Crank and Sync Shielded Cable Connections
- Use x1 2-core shielded cable for Pins B5 and B6
- Use x1 2-core shielded cable for Pins B7 and B8
NoteNOTE The individual core colours are not specified but there MUST be at least one different core colour between the Crank Index cable and Sync Sensor cable — i.e. the exact same cables cannot be used for both connections.
3.5 Knock Shielded Cable Connections
- Use x1 2-core shielded cable for Pins B16 and B17
- Use x1 2-core shielded cable for Pins B24 and B25
NoteNOTE The individual core colours are not specified but there MUST be at least one different core colour between the KNK 1 cable and KNK 2 cable — i.e. the exact same cables cannot be used for both connections. Ideally these core colours should also be different to those used in section 3.4.
