I crawled underneath my dashboard and this is what I found. Three different plugs, of which NONE will accept the Tekonsha Prodigy P3 plug kit I purchased that was supposed to work with FORD(plugs on BOTH ends).
Now, this pigtail harness came with my manuals (inside the black bag). It has 4 pins. I am thinking this "may" connect to that "4 pin" plug from underneath my dashboard (grey)? Then... I connect the other Tekonsha Harness that I purchased (with one end pigtail, the other end with plug that connects to my brake controller?
