Recommendation of 7-Way to 7-Blade and 4-Pole Wiring Harness on an RV

Question:

I am looking for a converter to fit my RV trailer wire. I have a 7 blade. I want a converter from 7 blade to 7 blade with a 4 pin flat. I want to tow a car dolly with electric brakes and plug in additional lights for my car on the car dolly. Hope this makes sense.

The Hopkins Adapter 4-Pole to 7-Pole and 4-Pole # 37185 can be a solution for you. But we don't carry an adapter to plug into your RVs existing 7-way trailer connector to give you both of the connectors you want.

On the Hopkins adapter, the 4-Way plug isn't going to just plug into your RV so you're going to need to cut the 4-flat end of it off. Then you'll also cut off the 7-Way that's currently on the RV. After that you'll essentially wire the Hopkins adapter and the wiring on your RV together giving you both a 7 and 4-Way to use simultaneously. This option will give you a more professional look.

Another option would be to simply splice in a 4-way flat connector like part # 18252, so you have both connectors available.
