Item Type: Trailer Wiring HarnessMaterial: ABS and wiring harnessPart Number: 56217Product Wiring connectors are the easiest way to outfit your vehicle and make trailer wiring connections. They are manufactured using some of the most advanced technology in the industry, and each one is customized to work with specific makes and models. Some vehicle manufacturers install a special receptacle on the vehicle for vehicle to trailer wiring. While not every vehicle is equipped with this special receptacle, the wiring connector (also known as a T connector) utilizes this receptacle for a simple, stress free installation. Rather than requiring you to cut, splice and solder into your vehicle's wiring system, custom wiring connectors use a single OEM compatible plug and instantly provide a standard, universal vehicle to trailer wiring connection, typically in a 4 way form flat. All wiring connectors are manufactured for specific vehicles for the easiest installation and best fit. This special plug in connector offers a 4 way flat receptacle designed for custom wiring options for specific years of fit for RX350 (factory tow package may be required; to verify your vehicle compatibility, see application information) It comes with all the hardware needed to make a solid connection. It also comes with a dust cover to keep the connector receptacle clean when not in use. To ensure lasting reliability, all wiring connectors are thoroughly tested for optimal function. Stress is the last thing you should feel whether you're towing your RV to your favorite campground, an ATV to a hunting ground, or a fishing boat to a new hidden hot spot, we think your towing equipment should add to the enjoyment of your experience, not detract from it.Application:Replacement for Highlander 2008?2019Fit for RX350 without Factory Tow Package 2020?2021Fit for RX350L without Factory Tow Package 2021 1Compatibility: Wiring harness is replacement for Highlander 2008?2019, fit for RX350 without Factory Tow Package 2020?2021, fit for RX350L without Factory Tow Package 2021. 2Part Number: Trailer wiring harness replace part number is 56217.
