It's a wire color difference but not a function difference on the pins of the 7-way. The difference comes from the fact that the two different styles are representative of two different areas that uses trailers. Traditional is usually seen on equipment, utility and cargo trailers. Whereas RV standard is for campers and travel trailers. They both basically started doing their own thing and are too stubborn to adopt the other side. HA!
A lot of it has to do with the fact that there are so many trailers already out there wired each way that if either changed it would still cause confusion.
