* Ford Parts Websites: The best place to start is a website that sells Ford parts. These sites often have diagrams integrated into their parts lookups. You'll need to know your specific F-150 trim level (XL, XLT, FX4, etc.) and possibly the body style (regular cab, extended cab, crew cab) to get the correct diagram. Searching on the websites of major auto parts retailers (like AutoZone, Advance Auto Parts, Napa Auto Parts) and entering your vehicle's information is a good approach. Look for options like "parts catalog," "diagram," or "schematic."
* Online Parts Dealers (e.g., eBay, Amazon): While not always providing diagrams, some online retailers specializing in Ford F-150 parts might include images of the specific parts they're selling. These images can sometimes show the part's location on the truck.
* Repair Manuals: A comprehensive repair manual (Haynes or Chilton) for your 2004 Ford F-150 will likely have diagrams and illustrations showing the exterior body panels. These manuals are often available online or at auto parts stores.
* Ford's Website (potentially limited): While Ford's official website is geared toward new vehicles, you might find some limited information, though likely not detailed diagrams for such an older model.
Important Note: The diagrams you find will likely show parts by their individual names (e.g., "front bumper fascia," "driver's side fender," "hood"). You'll need to visually correlate these names to the specific part you're looking for on your truck.
