| This is a digital input to the ECU. The default "value" seen by the ECU for this input is +5v (when nothing is connected to the input or when the device connected to that input is simply "inactive"). When the input is "active", the external device is expected to pull this signal to ground, which will cause the ECU to no longer see the +5v value and instead see ground reference through the transistor. | This is a digital input to the ECU.
