Trailer Wiring Extension Harnesses

A trailer wiring extension harness provides the perfect way to route a 7-way RV blade connector from the back of your pickup into the truck bed for towing goosenecks, 5th wheels and other heavy-duty trailers. You can plug into your existing 7-way truck trailer wiring harness or branch off to retain use of both sockets for all-around ease and convenience.
