NoteNOTE 1 The Sensor 0V Ref pin (A4) is a specialised ground output for all analog sensors. Connect direct to the sensor 0V pin, DO NOT connect to the Engine Block or ECU Ground.
WarningNOTE 2 Ignition Outputs are TTL level designed to drive Ignitors. DO NOT connect directly to a coil.
ImportantNOTE 3 The HOT pin (B1) should be supplied with a constant 12V supply. This pin is used for fly-wheeling and allows an ECU managed power-down procedure.
