Some brief history behind Pro Plug from the developer, Karl Wagner: I have connected and serviced my share of trailer plugs over the years and became increasingly frustrated with the difficulty of connecting wires to them, which is inherent to their designs. In addition, the mounting requirements for the towing vehicle plug have changed very little over time, not keeping up with new applications. Currently, either drill a big hole in the vehicle for the plug to mount into or hang it from a bracket that has the big hole in it, often placing the plug in a vulnerable location. Both of these options require considerable depth behind the mounting plane for the connector housing to protrude and for the routing of the wiring into the connector housing. After owning a plethora of vehicles that needed trailer connectors for which the above mounting options did not work, I went to work on designing a connector system that would side-step convention with a focus on simplifying the installation and service aspects over current products. The result is Pro Plug, an easy to wire, easy to install, self-testing, surface mount 7 way RV electrical connector that makes it possible to install a connector where it couldn't before. It works great inside pickup beds for campers and 5th wheels as it can be mounted high on the inside of the bed wall protected under the top bed rail. Pro Plug also works great as a replacement connector on the mid 90s GM pickups, Suburbans, Yukons and Tahoes with the factory receiver hitch that leaves little room to install a plug, on motor homes and trailers on the rear bumper where the sewer hose is stored, many aftermarket receiver hitches with a flat tube cross bar, and the list goes on.....
