- The Ignition ON wires power essential systems like the fuel pump, engine control module, and dashboard indicators when the key is in the ON position.
- The Accessory (ACC) wire powers convenience features like the radio and power windows when the key is in the ACC position, even when the engine is off.
- The Start wire sends a signal to the starter solenoid to crank the engine.
Understanding these circuits is paramount for any DIY mechanic or even a professional technician.
