CURT – Custom Wiring Harness (5-Way Flat Output) (Part No.56594)

Custom Wiring Harness (5-Way Flat Output)

from

$66.99
A CURT custom wiring harness (also called a T-connector) is a simple, plug-and-play electrical device that eliminates the need for cutting, splicing and soldering when installing vehicle-to-trailer wiring. Most vehicles do not come ready to tow. Unless your vehicle has a towing package, it is probably not equipped with a trailer wiring connector. This is where CURT’s custom wiring harnesses come into play. Custom wiring harnesses plug into your vehicle’s electrical system using original equipment (OEM) connectors. Our custom wiring harnesses use two or more OEM connectors to plug in at the taillight assembly and provide a standard trailer socket to allow a trailer to be plugged into your vehicle’s power system. This harness provides a 5-way flat connector socket and is designed to be a custom wiring harness for certain years of the GMC Terrain or Chevrolet Equinox (to verify your vehicle compatibility, see the CURT application guide at curtmfg.com). CURT custom wiring harnesses are long-lasting and quick to install. They come with dust covers to keep your connector clean when not in use and feature a one-year limited warranty to give you peace of mind.

Product Features:
  • Plugs into vehicle tail light assembly to provide a 5-way flat socket
  • Simple plug-and-play design eliminates the need for cutting or splicing
  • 5-way flat connects tail lights, brake lights, turn signals and reverse lights
  • Dust cover included to keep connector clean when not in use
