Yd25 Ecu Pinout Free [extra Quality] Access
The ECU sends ground or pulse-width modulated (PWM) signals through these pins to control mechanical components.
To help you find the exact diagram, could you tell me the of your vehicle and if it's a D22, D40, or R51 model?
Typically uses a 4-pin connector: Pin B (Voltage), Pin C (Signal), and Pin D (Ground). Actuators: Fuel Injectors:
If you are performing a full engine swap (e.g., putting a YD25 into a older D22 Navara or a buggy), a simple pinout is rarely enough. You will likely need the full "Wiring Diagram System" (WDS) to understand how to bypass the NATS (Nissan Anti-Theft System).
