* Haynes or Chilton Repair Manuals: These are readily available at auto parts stores, online retailers like Amazon, or even libraries. They typically include detailed wiring diagrams. Make sure you get the manual specifically for a 1984 Pontiac Firebird.
* Factory Service Manual: This is the most comprehensive source, but also the most expensive. You might find a used copy online through eBay or other used booksellers. These manuals often have much clearer and more detailed diagrams than the Haynes/Chilton alternatives.
* Online Forums: Websites and forums dedicated to Pontiac Firebirds (like the Third Gen Firebird forums) might have members who have scanned diagrams or have links to downloadable resources. Searching within these forums for "wiring diagram 1984 Firebird" or similar terms might yield results.
* Automotive Parts Websites: Some large auto parts retailers' websites (like AutoZone or Advance Auto Parts) may offer access to wiring diagrams, often for a fee, once you've selected the year, make, and model of your vehicle.
Important Considerations:
* Variations: Wiring diagrams can vary slightly depending on options (like air conditioning, power windows, etc.) Make sure the diagram you find matches your car's specific features.
* Accuracy: Always double-check any wiring diagram you find against your car's actual wiring. Incorrect information can lead to electrical problems or even damage.
* Safety: Working with car electrical systems can be dangerous. If you are not comfortable working with electricity, it's best to consult a qualified mechanic.
Starting with the Haynes/Chilton manuals is usually the easiest and most cost-effective approach. If you need extreme detail or can't find a suitable diagram elsewhere, then the factory service manual is your best bet. Remember to be cautious and prioritize safety when working with your vehicle's electrical system.
