Understanding Your 2002 Chevy Tahoe Factory Radio Wiring Diagram
The 2002 Chevy Tahoe Factory Radio Wiring Diagram is a detailed schematic that illustrates the electrical connections for your vehicle's original factory-installed radio. Think of it as a map for the electricity that flows through your dashboard, powering your sound. It shows you what each wire is for, where it comes from, and where it goes.

Knowing the proper wire colors and their corresponding functions is absolutely essential for a safe and successful installation or repair . For instance, a typical diagram might show you:
- Constant 12V Power: Usually a yellow wire, this provides continuous power to the radio to retain memory settings (like radio presets) even when the ignition is off.
- Accessory Power: Often a red wire, this powers the radio when the ignition is in the "accessory" or "on" position.
- Ground: Typically a black wire, this completes the circuit and prevents electrical interference.
- Illumination: An orange wire, this dims the radio display when your headlights are turned on.
- Speaker Outputs: These are usually labeled with specific colors and polarities (positive and negative) for each of the four main speakers.
A comprehensive wiring diagram will also often include information about:
| Wire Function | Typical Color (may vary slightly) |
