Dedicated ground loop for sensitive sensors to prevent electrical noise. Injector Signals
Informs the ECU the engine is cranking so it can provide a richer fuel mixture for starting. Critical Sensors
(MAP) sensors are providing steady voltage readings; incorrect data here can cause rich/lean running conditions. Are you currently working on an engine swap or diagnosing a specific fault like a no-start or rough idle? 4E-FE ECU Pinout and Wiring Details | PDF - Scribd
