If the 7-Way on your trailer is corroded past the point of cleaning it off then it would be best to replace it. You can use either the 7-Way Molded Trailer Wire Connector # H20044 or the 7-Way Molded Trailer Plug with Junction Box # HS381-9000, which is what I recommend using.

Aside from just covering it up with something to help protect it, you will want to put some Dielectric Grease # 11755 on your trailer connector. This grease will help to protect the pins from corrosion and moisture.

I have attached some review and installation videos that will assist you further with the installation of either product.

If you let me know the make/model/year of your tow vehicle and if it already has a 4-Way flat connector then I can also help you get setup with a 7-Way on your tow vehicle.
