The fuel inertia switch on a 1999 Ford Expedition is typically located
under the passenger side of the dashboard, near the passenger's feet. It's often behind a small access panel. However, the exact location can vary slightly depending on trim level. You might need to feel around or use a flashlight to locate it.
To be sure, you should consult your owner's manual. A diagram showing the location is the best way to find it quickly and accurately.
