Here are the factory radio diagrams you requested. Since you didn't specify which audio package your truck has I added all 3. I've cut the diagrams in half so you can view larger. The first diagram is the base system, Second is premium system, and third is hands free system. Hope this helps and thanks for using 2CarPros.
