Multi-Plug T-One Connect or Assembly 7-Way Flat P

The REESE Multi-Plug T-One Connect Assembly 7-Way Flat P is the industry standard trailer connector for towing applications across trucks, SUVs, and larger vehicles. If you're hauling a boat, utility trailer, or enclosed cargo, this 7-way flat connector ensures reliable electrical communication between your vehicle's brake lights, turn signals, and trailer lighting. Built by REESE—a trusted name in towing hardware since the 1950s—this connector assembly eliminates guesswork during installation and provides a plug-and-play solution for both OEM and aftermarket hitch receivers.

The 7-way flat design accommodates left turn, right turn, brake, tail light, ground, auxiliary power, and reverse light circuits—giving you full control over trailer lighting and brake function. The connector uses a robust flat pin configuration that resists corrosion and ensures secure seating, even after repeated hook-ups on job sites or long road trips. Weighing just 1.28 lbs with compact dimensions (7.6 x 3.75 x 8.5 inches), the assembly integrates cleanly into existing wiring harnesses without bulk or awkward protrusions. The contact points are engineered for low resistance, minimizing voltage drop and maintaining signal clarity to trailer lamps.

Mechanics and DIY enthusiasts choose the REESE 7-way flat connector for reliability across diverse towing scenarios—from seasonal boat launching to commercial fleet work. This assembly is compatible with standard Class II and Class III hitch receivers and adapts to both integrated vehicle wiring and retrofit installations. Whether you're upgrading an older truck or finalizing a new towing package, proper connector selection prevents brake light failures, trailer bounce warnings, and electrical faults that can sideline a trailer at the roadside. Installation typically requires basic wiring skills and standard hand tools; the flat blade design aligns easily without fumbling.
