CURT 55384 Replacement Vehicle-Side Custom USCAR 4-Pin Trailer Wiring Harness (QTY 1)

Manufactured by: Curt

Stress is the last thing you should feel when towing a trailer -- whether you're hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection.

They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring Though this special socket is not equipped on every vehicle, a CURT custom wiring connector (also called a T-connector) utilizes the socket for simple, stress-free installation.

Rather than requiring you to cut, splice and solder into your vehicle's wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard vehicle-to-trailer wiring connection, typically in the form a 4-way flat All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit This particular connector provides a 4-way flat socket while retaining use of the existing OEM socket.

It is designed to be a custom wiring option for a variety of vehicles (see application info to verify fitment with your vehicle) It comes with a dust cover to keep the connector socket clean when not in use..

Features:

  • Replacement OE 4-Way Flat Socket (T's into USCAR)
  • Plugs into USCAR connection to add 4-way flat and retain use of existing socket
  • Simple plug-and-play design eliminates the need for cutting or splicing
  • 4-way flat output connects tail lights, brake lights and turn signals
  • Dust cover included to keep connector clean when not in use
  • Slit loom keeps wires contained and well protected
  • Backed by a limited one-year warranty
