2005 Ford Excursion 7 Pin Trailer Wiring Diagram. I drew this crude diagram to help explain. to owner generated reviews, discussion, tech tips, and more! Need to replace a corroded or damaged Trailer Hitch Plug on your Ford Excursion model?
Ford makes no representation as to the suitability of the Excursion for snowplowing, in particular regarding the potential for exceeding vehicle weight limits. by Ford Motor Company (Author). Use the code that came with the plug. Being dyslexic it makes life even more exciting!!!
I found that the white (ground) wire from the four way flat was cut short inside the seven way shell, and only the fat white external ground wire was connected.
You should be able to easily find a Curt harness that plugs into that pig tail and give you the required wiring plug for your trailer.
Snowplowing The Excursion is not recommended for snowplow installation. Being dyslexic it makes life even more exciting!!! There is a long thread on this forum that has all the part numbers, it is all about trailer hitches.
