On a 1996 Ford F-150 with a 5.0L engine, the EGR valve is typically located on the intake manifold,
near the back of the engine, on the passenger side. It's often somewhat difficult to access and may be partially obscured by other components. You'll likely need to use a flashlight and possibly even remove some components for better visibility and access.
Because of the potential variation in exact location due to specific build configurations, it's best to consult a repair manual specific to your 1996 F-150 5.0L engine. A diagram will give you the precise location. You can find these manuals online or at auto parts stores.
