In the electronic engine control unit (ECM) incoming signals are received from the following system elements: 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26.
After processing the received data, the ECM sends control pulses to the following system elements: 20, 21, 22, 23, 24, 25, 26, 27, 28, 29.
Non-ECM items: 27, 28, 29.
Elements located on the ECM bus: 1, 2, 3, 4, 5.
