It meticulously details each wire's color, function, and connection point within the factory stereo and the vehicle's electrical system.

- Ground: A crucial connection that provides a safe path for electrical current to flow back to the battery.
- Speaker Wires: Each speaker in your vehicle has its own dedicated wire pair (positive and negative) for audio output.
- Illumination: This wire often dims the stereo's display when your vehicle's headlights are turned on.
