* Online Automotive Parts Websites: Websites like AutoZone, Advance Auto Parts, and Napa Auto Parts often have wiring diagrams available, sometimes for free but often requiring a paid subscription or purchase of a repair manual. Search their websites for "1974 Chevy Nova wiring diagram" or use their part lookup features and specify your Nova's details.
* Online Repair Manual Databases: Sites like Haynes.com and Chilton.com offer online access to repair manuals, many of which include complete wiring diagrams. These usually require a paid subscription.
* eBay or Amazon: You can sometimes find physical copies of factory service manuals or aftermarket repair manuals (like Haynes or Chilton) on eBay or Amazon. These usually contain detailed wiring diagrams.
* Local Auto Parts Stores: Check with your local auto parts store. While they might not have diagrams readily available, they may be able to access them through their computer systems or recommend a place that does.
* Chevrolet Forums: Join online forums dedicated to classic Chevrolets or specifically 1970s Novas. Enthusiasts often share information, including wiring diagrams, in these communities.
Important Considerations:
* Year and Model Specificity: Be absolutely certain of the year (1974) and your Nova's specific model and options (engine size, trim level, etc.). Wiring can differ significantly based on these factors.
* Accuracy: Always cross-reference information from multiple sources to ensure accuracy, especially when working with electricity. Incorrect wiring can cause damage to your vehicle or even injury.
Finding a free, high-quality diagram online can be challenging. Be prepared to invest in a paid resource for the most comprehensive and reliable information.
