Review on BougeRV 7 Way Trailer Plug: Weatherproof Wiring Harness with Junction Box for RV Trailers, Campers, Caravans, and Food Trucks - Enclosed Trailer Accessories by Ruben Saunders

Regardless, a few minutes with an ohmmeter solved the problem. Also, in the unit I received, the ring posts are secured with an M5 x .08 hex nut, which is available at most hardware stores.

If you search the web, be careful as a lot of incorrect information is presented. So use a trustworthy website.
