I was able to find the following pics online.


Any help here is appreciated.

Thanks.

Sorry. But these plugs must be one of the most highly guarded secrets by Ford.

The problem I ran into with my own investigations of this is that the pins aren't always in the same place across the different years, and some years don't have a pinout, so it is almost impossible to do one comprehensive listing. I set out to do just that when I was researching my first 4.0 swap, thought I had it nailed, and posted my work as the "definitive answer" to this question. Then I grafted the one side onto my dash harness for the 2.9 and nothing worked. So I started over with a pair of later harnesses and repined an Explorer harness into a Ranger connector, finding it to be the most efficient way to add the wires missing from the Explorer harness. During the process, using three books I found that wires moved around and colors changed. After learning this I quickly pulled down my post intending to try and correct the mistakes later, once I had a working unit. Then mid-project my first kid was born, and I haven't had time to get back to it.

It isn't engine specific.
