The Power Steering pressure switch is screwed into the pressure line on the back of the power steering pump. The oil pressure sensor on the 5.9 L V8 engine is to the right of the distributor (left as you are looking at the engine from the front of the car), on the top of the engine block towards the rear below the edge of the hood opening. You may need to use a light to find it, as it's behind the carburetor and tucked under the distributor wires.
