Product Details

Adapter by CURT®. There are several different types of connectors used to supply power from a tow vehicle's electrical system to a trailer's wiring system. Some trailers only need the bare essentials - running lights, brake lights and turn signals - while others require a connection for reverse lights, electric brakes and auxiliary power.

With connectors ranging from simple to complex, it may be the case that the connection between your vehicle and your trailer is not a perfect match. For example, your truck may be equipped with a 6-way round socket, but your trailer may have a 4-way flat plug. For this very common problem, CURT offers a quick and simple solution in the form of an electrical adapter. An adapter is an electrical device that allows a connection to be made between a mismatched trailer plug and vehicle socket. It easily plugs in your vehicle's electrical socket and usually requires no additional wiring. CURT offers an array of adapters to accommodate most types of plugs and sockets, including 4-way flat, 4-way round, 5-way flat, 6-way round, 7-way RV blades and more.

CURT manufacturing is one of the premier trailer hitch and towing accessories suppliers in the industry. It produces everything you may need: hitch pins to hold the ball mount to the receiver, clips to hold in the pins, safety chains, tongue jacks, sway controls, equalizing hitches, tail light conversion controllers, tongue jacks, wheel chocks, the list goes on. Towing a trailer isn’t like driving car; the extra weight means you have to be prepared for many contingencies. CURT makes products that are calculated to make it easier to hook up your trailer, make it tow more easily and more safely, and keep you at ease while doing so.

Must Have!
If you own a Audi, VW, or Porsche SUV and plan to tow anything with it, this is a must have. It keeps the warning lights from coming up on the dash, and it simple and play installation.

2025 Chevy Trax Trailer Wiring Hook Up
Recently purchased a 2025 Chevy Trax and Installed a Trailer Hitch and needed a plug and go Trailer Harness, I bought the Curt T-Connector which was a perfect fit and also included all necessary connectors and directions, you will need to purchase the plastic tools to help in the removal of components in back of trunk to gain access to car harness to hook it all up, after hook up I plug in trailer to car and all lights worked perfect, its a good clean set up.

Easy to install
This is replacing one that I installed about 5 years ago and quit working. I wish it would have lasted longer but the fact that it is plug and play made the replacement not so difficult.

Wired backwards?
This item appears to be wired backwards. At the end that plugs into the vehicle with the clip side up the wiring, from left to right, should be white, brown, green and yellow. It is actually green, yellow, brown and white.

Works 10% of the Time.
Left flasher acts like if rear bulb was burnt, but it sometimes works.

Very Easy Installation and Use.
Between the instructions provided and information on YouTube, the installation of the T-Connector is easy. For testing, installers should buy a flat-4 cable (LED) tester; they only cost a few dollars. The only criticism that I have is the self-tapping screw provided to secure the earth cable. It didn't at all look fit for purpose.
