* Chevrolet Service Manual (Factory Manual): This is your best bet. A factory service manual will have detailed wiring diagrams, often broken down by system. You can sometimes find these online as PDFs (be wary of questionable sources), or purchase a physical copy from online retailers like Amazon or eBay, or from automotive parts stores. Specify that you need the manual for a 1996 Chevrolet Cheyenne.
* Online Automotive Repair Databases: Websites like AllDataDIY or Mitchell1 offer online access to repair information including wiring diagrams. These are subscription-based services, but usually offer a free trial period. They're generally considered the most accurate and comprehensive sources.
* Haynes Repair Manual: Haynes manuals are less detailed than factory manuals, but often provide a simplified overview and may include some wiring information. They're generally cheaper than factory manuals.
* Local Auto Parts Store: Some auto parts stores (like AutoZone, Advance Auto Parts, or NAPA) might have access to wiring diagrams on their computer systems. They may print a relevant section for you if you describe exactly what you need. However, the level of detail and accessibility can vary.
Important Considerations:
* Engine Size: The fuel system wiring might slightly vary depending on the engine size (e.g., 4.3L, 5.0L, 5.7L, etc.) in your 1996 Cheyenne. Make sure you specify your engine when searching for a diagram.
* Diagram Complexity: These diagrams are often complex, using symbols and color-coding. Take your time studying them and familiarize yourself with the symbols before attempting any electrical work. Incorrect wiring can be dangerous.
* Safety: Always disconnect the negative battery terminal before working on any electrical system. Fuel is flammable, so work in a well-ventilated area and take appropriate safety precautions.
Remember, if you're not comfortable working with automotive electrical systems, it's best to consult a qualified mechanic. Incorrect wiring can lead to serious damage or injury.
