A 2005 Scion Xb radio wiring diagram is essentially a visual roadmap of the electrical connections within your car's audio system. It illustrates how the radio unit communicates with various components such as the speakers, power source, antenna, and potentially other features like steering wheel controls or auxiliary inputs.

Power Wires:
These are the essential lifelines that supply electricity to the radio.
- Constant Power (usually yellow): Provides power to the radio even when the ignition is off for memory functions like presets.
- Switched Power (usually red): Powers the radio only when the ignition is in the accessory or on position.
- Ground Wire (usually black): This wire provides a return path for electricity to the vehicle's chassis, completing the circuit.
- Speaker Wires: These carry the amplified audio signal to each individual speaker. They are typically color-coded to correspond with specific speakers (e.g., front left, front right, rear left, rear right).
- Illumination Wire (usually orange/white): This wire dims the radio display when your headlights are turned on.
- Antenna Trigger (usually blue): This wire activates a power antenna if your vehicle is equipped with one.
