- Switched Power (Accessory Power): This wire receives power only when the ignition key is turned to the accessory or run position. It's what allows the radio to turn on and off with the car.
- Ground: This is a crucial connection to the vehicle's chassis, providing a return path for the electrical current. A poor ground connection is a common cause of radio issues.
- Speaker Outputs: These wires carry the audio signal to each individual speaker. They are usually color-coded to correspond with specific speakers (e.g., front left, front right, rear left, rear right).
- Illumination Wire: This wire connects to the vehicle's dashboard lights, causing the radio display to dim when the headlights are turned on.
