* Your Owner's Manual: This is the best place to start. The owner's manual should have a detailed diagram showing the location of the fuse boxes (there's usually more than one) and which fuse controls which circuit.
* Online Ford Resources: Websites like the official Ford website (though finding a specific diagram for an older model might be tricky), or parts websites like FordParts.com might have downloadable manuals or diagrams. Search specifically for "2006 Ford Mustang fuse box diagram".
* Repair Manuals: Comprehensive repair manuals (like those from Haynes or Chilton) will contain detailed fuse box diagrams and information. You can usually find these at auto parts stores or online retailers.
* Online Forums: Searching online forums dedicated to the 2006 Ford Mustang (like Mustang forums) might yield results. Someone may have already posted a picture or scan of their fuse box diagram.
Important Note: There are usually two fuse boxes in a 2006 Mustang: one under the hood and one inside the passenger compartment (often located under the dashboard). Make sure you're looking at the diagram for the correct fuse box. When searching, specify "underhood fuse box" or "interior fuse box" as appropriate.
