3.2 Pin B10 Sensor Ground Branched Connections

Pin B10 (Sensor Ground) is a branched connection feeding the analog sensor 0V references.

Pin B10 (Sensor Ground) is a branched connection feeding the analog sensor 0V references.

3.3 Pin B2 5V Supply Branched Connections

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.

3.6 Ethernet Sub Harness - Pins B31-B34

See the document “Ethernet to Superseal Loom Specification V1.x”. This sub harness should be plugged into Connector B, Pins B31 → B34.
