* Online Forums and Communities: Websites and forums dedicated to classic Dodge trucks are your best bet. Search on sites like:
* DodgeTalk.com: This is a large forum with many knowledgeable members who often share information and even scan diagrams. Be sure to specify the year, model (e.g., D100, D150, D200, etc.), and any options your truck has.
* ClassicCars.com forums: They might have sections dedicated to specific years and models.
* Facebook groups: Search for groups dedicated to 1970s Dodge trucks or specifically 1978 models.
* Online Parts Suppliers: Some online parts suppliers, like those specializing in classic car parts, might offer wiring diagrams as downloadable PDFs, although they often require you to create an account.
* Haynes or Chilton Repair Manuals: These manuals often contain wiring diagrams. Look for one specifically for your 1978 Dodge pickup. You might find used copies at a reasonable price on eBay or Amazon. Make absolutely sure it's the correct year and model.
* Local Auto Parts Stores: While less likely to have a complete wiring diagram readily available, a knowledgeable parts counter employee might have access to some information or be able to suggest resources.
* eBay or Amazon: Search for "1978 Dodge pickup wiring diagram." You might find someone selling a scanned copy or a reproduction of the original factory manual.
Important Considerations:
* Specificity is Key: The more details you can provide (engine size, trim level, options like power windows, air conditioning, etc.), the better your chances of finding the correct diagram.
* Factory Diagram is Best: While aftermarket diagrams exist, they might not be entirely accurate. A factory diagram is always the most reliable source.
* Safety First: Working with automotive electrical systems can be dangerous. If you're not comfortable working with electricity, consult a qualified mechanic.
Remember to be patient; finding the precise diagram might take some time and effort. Good luck with your repairs!
