An Explorer 5.0 is as plug-and-play as they come, at least for OBD-II trucks like yours. I have yet to see ANYONE with a 4.6 in anything but a Gen 1 Ranger... Lots of people talk up a good game but I have yet to see a single person pull it off... Allegedly there is a twin-turbo 5.4 Ranger floating around, but when I asked the guy for pictures he quit talking to me. So odds are its non-existent. Stick with the Explorer 5.0.. and the search button. Everything you need is already in the library.
