* Owner's Manual: The most reliable source. Check the owner's manual's index or table of contents for "fuses," "fuse box," or a similar term. It should have a diagram showing the fuse locations and what each fuse protects.
* Inside the Fuse Box: The fuse box itself often has a diagram printed on its inside cover or lid. This diagram might be small or faded, but it's a good starting point.
* Repair Manual: A Haynes or Chilton repair manual for your specific year and model of Lincoln Town Car will almost certainly contain a detailed fuse diagram and other electrical system information. These are available online or at auto parts stores.
* Online Forums and Websites: Websites like Ford-specific forums (search for "Ford Lincoln Town Car forums") or general automotive repair sites might have someone who has scanned and shared a fuse box diagram. Be cautious and verify the information against other sources.
If you can't find it in your owner's manual or the fuse box, a repair manual is your best bet for a clear and accurate diagram.
