Go to the service manual sticky and follow the directions till you get to your model and year and click the "Electrical Troubleshooting" tab. Then select the "How To Use" tab and go down to page 5. There is a useful wire color coding chart, copy it for future use. Then go to the "Circuit Diagram Index" and select your radio.
