- Speaker Outputs: Identifying the wires for each individual speaker (front left, front right, rear left, rear right, and any subwoofers) is essential for proper sound distribution and wiring.
- Accessory Wires: These can include things like illumination wires (which dim the stereo display with headlights), antenna control, and remote turn-on wires for amplifiers.
