(888) 312-8812 Login SignupDriving through different environments requires a trailer wiring connection that won’t disconnect under stress. The Tectran Trailer Wiring Plug offers a 7-way setup that supports auxiliary functions and includes a male ground pin. This version includes a spring guard to help manage strain and vibration from movement between the tractor and trailer. Electrical connections between heavy-duty vehicles and trailers rely on secure contact to power lights, brakes, and signals. Don’t risk using a damaged tool—turn to the Tectran 680-E71SG to support your trucking needs.
