Seven-blade to six-pin adapter enabling older truck connectors to power modern trailers with electric brake systems. The corrosion-resistant tin-plated terminals maintain clean contact across repeated connections and disconnections, and the switchable center pin toggles between auxiliary 12-volt power and brake-signal lines without adapter changes.

Black plastic body withstands UV and temperature swings common in RV storage, and the connector geometry accepts both blade and pin styles without modification.
