1. The first place to check is the owner's manual. Many owner's manuals include a wiring diagram for the vehicle.
2. If you don't have an owner's manual, you can also find wiring diagrams online. Several websites offer wiring diagrams for free or for a small fee.
3. Another option is to purchase a Haynes or Chilton repair manual for your vehicle. These manuals typically include detailed wiring diagrams.
4. Finally, you can also contact a local Chevrolet dealership and ask for a wiring diagram. They may be able to provide you with one for free or for a small fee.
Here are some websites that offer free wiring diagrams:
