Product Details

Universal Butt Connector by CURT®. Like trailer hitches and ball mounts, electrical connectors range all over the board in shape, size and capability, but no matter what your trailer's electrical functions are, you need a solid connection to keep the power flowing and ensure safety on the road. CURT electrical connectors are designed and manufactured to give you a reliable connection every time you plug in your trailer. This 4-way flat connector is designed to supply power for tail lights, turn signals and brake lights, as well as a ground connection.

Even if you've already hitched your trailer up, you're not actually ready to hit the road. What you also need to do is ensure the trailer has enough power to run turn signals and brake lights. That's why you need this T-connector. CURT applies SMT (surface mount technology) to any T-connector with a built-in converter, which allows for lower resistance, less heat generation and longer life cycle. The majority of CURT T-connectors require neither splicing nor cutting or taping, however if the length is not appropriate, you can cut the connector to appropriate length and splice it to the tail light wiring. Custom-designed to precisely fit your vehicle, this T-connector is created to deliver unsurpassed levels of performance, reliability and durability.

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.
