When you look at a typical 2000 Pontiac Grand Am radio wiring diagram, you'll encounter various color codes and wire designations. These are standardized to some extent, but always refer to the specific diagram for your vehicle. Here's a general breakdown of what you might find:
- Constant Power (often yellow): This wire provides continuous power to the radio, even when the ignition is off, allowing the radio to remember your settings (like radio presets).
- Accessory Power/Ignition (often red): This wire receives power only when the ignition is turned to the accessory or run position. It powers the radio when the car is on and turns it off when the car is off.
- Ground (often black): This is a vital connection to the vehicle's chassis, completing the electrical circuit.
- Illumination (often orange or orange/white): This wire dims the radio display when your headlights are turned on.
- Speaker Outputs (various colors): These wires carry the audio signal to each of your car's speakers. Typically, each speaker will have two wires, one for positive and one for negative.
Here's a simplified look at some common connections you might see in a 2000 Pontiac Grand Am radio wiring diagram:
| Wire Color (Common) | Function |
