Check Vehicle Fit

A CURT custom vehicle-to-trailer 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 vehicle-to-trailer 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 4-way flat connector socket and is designed to be a custom wiring harness for certain years of the Chrysler Aspen, Dodge Dakota pickup, Dodge Durango, Jeep Grand Cherokee, certain Dodge Ram trucks or certain Dodge Sprinter vans (to verify your vehicle compatibility, see the CURT application guide at CURT custom vehicle-to-trailer 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 4-way flat socket

  • 4-way flat output connects tail lights, brake lights and turn signals
  • Dust cover included to keep connector clean when not in use

  • Q:

    I just bought this product and it does not appear to be able to fit either OEM connector in the tail light nor at the bottom going into the bumper I assume into the back up sensors/cam. It appears the products connectors are larger then both connectors in the vehicle. I have a 2008 Chrysler Aspen limited edition without the tow package.

      No, Louie! This Curt Custom Vehicle-to-Trailer Wiring Harness (Part No. 55381) fits only for vehicles with factory tow package and it does not fit your 2008 Chrysler Aspen Limited (without tow package). However, I'd recommend you to return the wiring harness to the nearest store and they will process the refund.

  • Q:

    I have a 2005 Durango and just installed a tow bar for a boat I just bought. The guy who sold the boat gave me the black cylinder piect that I believe plugs into the 4 part wire from the trailer. Is this the product I need to install to the Durango in order to get the brake lights and turn signals to work on the trailer?
