Need to replace a corroded or damaged Trailer Hitch Plug on your Ford Excursion model? Without a factory wiring diagram, I don't know where else to look. 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.
All makes and models are designed differently, so you'll need to have a service or repair.
Try <font color="blue">THIS LINK</font> to a wiring diagram page that probably has what you.
Use the code that came with the plug. We have the plug-and-play harnesses for the job with no need for cutting and T-One Connector by Tekonsha®. It has the seven pin connector.
