On typical late-90s Nissan electronic fuel injection diesels (such as the Terrano, Patrol, or Caravan), the Zexel ECU connector often utilizes a multi-row high-density plug.
A safety valve that cuts off fuel delivery immediately when the ignition is switched off. Engine Sensors and Inputs
Unlike a modern ECU that manages hundreds of parameters, the Zexel ECU in these diesels is primarily a . It governs the injection timing, fuel quantity, and cold start advance on inline injection pumps (often Zexel’s own “distributor-type” pumps or “inline” pumps). nissan zexel ecu pinout
The Zexel ECU manages the Bosch VP44 fuel injection pump (manufactured under license by Zexel). It utilizes a high-pin-count connector to interface with various engine sensors and actuators to maintain optimal performance and emissions. Primary Pin Functions
Remember: always triple-check wire colors against your specific vehicle year and market. Nissan changed pin assignments subtly between the Japanese Domestic Market (JDM), European, and Australian (ADM) models. On typical late-90s Nissan electronic fuel injection diesels

If you swapped an automatic TD42 to a manual transmission, the Zexel ECU expects a ground on the neutral position pin (refer to your specific pinout – often Pin B21). Without it, the ECU limits RPM to 2500.
