You could always go to your local auto parts store (pep boys, autozone) and buy a Chiltons or Haynes Manual for the car, they have easy to follow instructions on doing just about anything to your car... I have an I4 in my car so my plug wires are right there at the top of the engine, very simple, a monkey could do them, I don't know about the Duratec engine though, never worked on one, except changing the oil...
