The ECU typically consists of several multi-pin connectors (often labeled A, B, C, D, or E). Key pins you will frequently need for diagnostics or wiring include: +B / +B2: Main ECU power from the EFI relay. BATT: Permanent battery power for ECU memory. E1 / E2 / E01: Main chassis and sensor grounds. Sensor Inputs:
