Understanding Your 2015 Ford Focus Radio Wiring Diagram
The 2015 Ford Focus Radio Wiring Diagram is a schematic that visually represents how the radio and its associated components are connected within your vehicle's electrical system. It details the power, ground, speaker outputs, antenna, and control signals for the factory-installed audio unit.

- Ground: This is essential for completing the circuit and ensuring proper operation of the audio system.
- Speaker Outputs: These are typically color-coded to correspond with specific speakers (e.g., front left positive, front left negative).
- Illumination/Dimmer: This wire controls the brightness of the radio display.
- Antenna Remote Turn-On: Used for powered antennas or to activate external amplifiers.
