Round 7 Pin to RV Blade 7 Pin Trailer Adapter
This 7 pole round pin to 7 pole rv trailer adapter converts your 7-way round pin connector to RV 7-way blade connector, perfect to solve mismatch problem between your truck and trailer connection.
The factory 7 way round pin connector can vary from vehicle to vehicle, pins for turn signals and tail lights are standard but not so for 12V power, backup lights and brake control pins. we suggest getting a tester and making sure that the pins on the 7-way blade connector are doing what you expect before you hook up a trailer or you may end up with the electric brakes locked on, etc.
