Viewed looking into ECU header (or wire side of loom connector)

 

Note: Gnd Out is also known as Sensor Ground.

*Note: Version 3 or newer G4X Monsoon ECUs support Knock control which is fed into the ECU through pin 6 (shared with DI4, you can either use DI4 or Knock control, not both). Versions prior to 3.0 do not have knock control hardware.
