If the plastic piece showing the diagram is missing on your car, you can call the Ford dealership and have them e-mail it to you. They did that for me. I can tell you there are many places on the web (and many auto parts stores) which will show you the "correct" diagram for a car, but are completely wrong!!! I got about 4 or 5 "correct" diagrams for my Ford Windstar, all of which were wrong. it wasnt until i called the dealership and spoke with the parts dept. was I able to finally get a diagram that worked.
