The 4.6 does not have an traditional distributor. This year engine should have two coil packs located on the front of each valve cover. Each coil pack controls four cylinders. Some of the plug wires will cross over the front of the engine in a wire loom on top of the alternator. The spark plugs are located down in the intake manafold. they run beside the fuel rail on each side of the intake manafold where it joins to each head. You will need an extention at least 8 to 10 inches long to get at the spark plugs. The plug wire fit snuggly into the intake manafold and have an extention on them that connects to the spark plug.
