How to Read a Wiring Diagram
The 03 Tahoe radio wiring diagram is divided into several sections. Each section corresponds to a different part of the vehicle’s electrical system. Here is a quick breakdown of the different sections:

| Communication Network | This section shows how different modules communicate with each other. |
| Inputs and Outputs | This section shows the inputs and outputs of different modules. |
