The of an ECU refers to the detailed specification of which signals are carried on each pin of the ECU's connector(s). It's essentially a map that shows:
with open-source engine control software to build custom standalone ECUs. 2. ECU Pinout Identification ecu+design+pinout+full
Then she disconnected the harness, sealed the ECU with epoxy (better than factory), and handed it to Kael at dawn. The of an ECU refers to the detailed

An ECU pinout refers to the function of each electrical pin within the ECU’s connector. A includes every terminal—power, ground, inputs, outputs, and communication lines.
