Ok all, I have been having issues with trailer lights. Found chaffed wires behind the factory plug and I'm replacing the plug itself since it starting to look worn. Question is this. I have an extra wire that looks like it was just cut off, but no place for it to go int he 7 pin plug. Any ideas

Theres no plug on it? Its just cut? You could get a test light and see what it for. I heard they use to add a wire incase someone added a truck cap so they could put on a 3rd brake light :cool:
