Effortless trailer wiring with MECMO

The MECMO 7 Way Blade to 4 Way Trailer Adapter Coiled Wiring Harness is designed to simplify your towing setup. It converts a vehicle's 7-pin blade receptacle to a standard 4-pin flat trailer connector, letting you power trailer lights without juggling multiple adapters.

Stretchable coil design for flexible towing

  • Up to 5 ft of total length, with a comfortable stretch between 3 and 4 ft
  • Coiled construction keeps wiring off the ground and reduces tripping hazards
  • Resilient rebound maintains a tidy length after use

All-in-one 7-to-4 connection

  • Turns vehicle 7-way blade plug into a 4-wire flat trailer connector
  • Eliminates the need for separate adapters for common trailer lighting systems
  • Ideal for trailers with 4-prong lighting plugs

Durable, weather-ready build

  • PU jacketed cable offers flexibility in cold or hot conditions
  • Pure copper conductors with tin-plated terminals for corrosion resistance
  • Dust cover on the 4-pin socket helps keep terminals dry and clean

Simple, plug-and-play installation

  • Plug the vehicle’s 7-blade end into your car’s 7-way receptacle
  • Connect the trailer’s 4-pin flat plug to the opposite end
  • No special tools required for setup

In real-world use, you may encounter different trailer types, boats, or RVs. This coil-ready adapter offers versatility and a cleaner towing setup, without making guarantees about performance. It aims to provide a practical, ready-to-use solution that fits into your existing wiring system.

Materials and longevity

  • Flexible PU jacketed construction can handle regular flexing and bending
  • Copper conductors paired with tin-plated terminals for reliable conductivity and corrosion resistance
  • Dust cover protects the 4-pin socket from moisture when not in use

Whether you’re mounting a utility trailer, boat trailer, or light-duty camper, MECMO offers a compact, easy-to-store option that can help keep your towing setup tidy and ready for the road. Consider this adapter as a practical enhancement to your vehicle-to-trailer wiring kit.
