Adapter Needed from 7-Way Round on Tow Vehicle to 7-Way Blade on Trailer

Question:

I have called in and talked to a couple different people. I always get different part #s so I am getting confused. I want to keep my semi tractor wiring to a semi trailer, also I want to plug into a rv style plug on gooseneck. What is needed? Thanks

I'm not too familiar with semi trailer wiring but I believe that you have a connector with a 7 round pin configuration like I highlighted in the top right of the attached picture.

To get to the 7-Way blade connector (also highlighted in the picture) that is on your gooseneck trailer you need the adapter # HM47425. This allows you to retain the wiring and connector on your semi trailer while being able to power up your gooseneck trailer.
