What is the fuse number 20 under the hood of a f250 super duty?

Answers from the Automotive Experts

Karen Salvaggio, Owner/ Editor Thunder Valley Racing and Professional Race Car Driver at Thunder Valley Racing From the Ford Truck Enthusiast Forum: "Fuse #20 in the power distribution box (located under the hood) is a 10A fuse for the trailer back-up lights (reference page 223 of the 2005 owner's manual). The fuse which powers the trailer brake controller is #20 in the passenger compartment panel and is a 15A fuse (reference page 219 of the 2005 owner's manual)." Hope this helps!!!

Stephanie Gutierrez, Marketing Communications Coordinator at Victory Auto Service & Glass Alicia, depending on the month of manufacture and the engine size, this could vary. But what I did find was this: #20(top) - 10amp Trailer Tow Stop and Left Turn Lamp. Otherwise, if you look in your owners manual, that would be the most accurate way to verify.
