Question:

When searching for a 7 pin wiring cable for my trailer I see some of them say RV Style and some dont. What is the difference?

It differentiates from how other 7-Ways are wired like agricultural and utility equipment. The Hopkins 7-Way item # HM20087 you were looking at is wired in the RV style which is consider standard. You do want one in the standard 7-way RV style. That's what the 7-way on vehicles use.

I have linked a diagram below that will break down the differences in the three different styles 7-ways come wired in. This diagram will also help you get the item # HM20087 installed on your trailer.
