Fortunately I found a really good write up online installing one of these on a Ford Expedition. It made the installation simple. There was one color wire I had left over from this plug that didn't match anything in the wiring harness for the expedition. At the moment I cannot recall what color it was or what it was for. I basically zip tied it short and wrapped it up with electrical tape to keep it out of the way. There's been no issues towing my wife's horse trailer the few times we've done it so far.
