- Switched 12V (Ignition): This powers the radio only when the ignition is on. Typically red.
- Ground: Completes the electrical circuit and is crucial for proper operation. Usually black.
- Speaker Wires: These come in pairs, with one positive and one negative for each speaker. Color codes vary, but are often marked.
- Antenna: Connects to the car’s antenna to receive radio signals.
- Illumination: Dims the radio display when the headlights are on. Usually orange/white.
