Effortless trailer lighting with a precision fit

The MECMO 4-Pin Trailer Wiring Harness 56217 is a custom-fit accessory designed for select Toyota Highlander and Lexus RX 350/350L models. Built to integrate with your vehicle’s electrical system, this harness provides a tidy, reliable path for your trailer lights—tail, brake, and turn signals—without invasive modifications.

Compatibility you can verify

  • Engineered for 2008–2019 Toyota Highlander (including Hybrid, Limited, XLE, SE, LE).
  • Also compatible with 2018–2021 Lexus RX 350 and 2018–2022 RX 350L (excludes Dual Exhaust variants).

Simple, plug-and-play setup

  • Connects directly to the factory pre-wired port behind the tail light.
  • Provides a standard 4-way flat connector to power the trailer’s lighting system.

Durability and protection matter on the road. The harness uses heavy-duty bonded wire and tin-plated copper terminals to resist corrosion and maintain solid conductivity even in tough conditions. A protective dust cover shields the terminals when not in use, helping keep dirt, moisture, and debris out of the connection.

Built to last and stay clean

  • Heavy-duty construction supports regular towing duties with consistent performance.
  • Protective features include easy-grip tabs for a secure hold and a dust cover for added protection.

For drivers seeking a straightforward upgrade, this MECMO harness offers a practical approach to trailer wiring that aligns with common towing needs. It’s designed to be user-friendly and non-intrusive, leaving you with a clean installation and dependable lighting support for your trailer during trips or errands.
