* Repair Manuals: A factory service manual (FSM) is the best source. These are comprehensive and very detailed. You can often find them online through retailers like Amazon or eBay, or sometimes from specialized automotive parts stores.
* Online Automotive Repair Databases: Sites like AllDataDIY, Mitchell 1, and Chilton offer online access to wiring diagrams and other repair information. These often require a subscription fee.
* Haynes Repair Manuals: Haynes manuals are less expensive than factory manuals but may not be as detailed. They *might* include simplified wiring diagrams.
* Local Auto Parts Stores: Some auto parts stores (like AutoZone, Advance Auto Parts, etc.) may have access to wiring diagrams through their computer systems. This is often free, but their access may be limited compared to a full FSM. Ask if they can print one out for you; availability varies.
Important Considerations:
* Specific Trim Level and Options: Wiring diagrams can vary slightly depending on the trim level (e.g., WT, LS, LT, etc.) and optional equipment (towing package, sunroof, etc.) of your Silverado. Make sure to specify this information when searching for a diagram. The VIN number is often helpful.
* Diagram Accuracy: Always double-check the information you find against your vehicle. Errors can be present in online or even printed diagrams.
It's crucial to work safely when dealing with automotive wiring. If you are not comfortable working with car electrical systems, it's best to take your vehicle to a qualified mechanic.
