Product Details

Universal Heave Duty 7-Way Connector by CURT®. A CURT connector provides a reliable connection for your trailer wiring, using an industry-standard format, such as a 4-way flat, 6-way round or 7-way RV blade. They can be used to install new wiring on a vehicle or trailer or as replacement connectors for existing wiring. This particular connector is a heavy-duty 7-way RV blade socket and is designed to mount on the vehicle-side of the connection, to accept a trailer wiring plug.

Once plugged in, it provides a connection for the taillights, turn signals, brake lights, backup or reverse lights, electric trailer brakes and a 12-volt battery. It also provides a connection for the ground wire. This trailer wiring connector is especially built to withstand the elements. It is constructed from durable black molded plastic to be impervious to rust, and it features a dust cap with a spring mechanism and water-resistant insert to keep out rain, salt, grime and dirt when the connector is not in use.

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.

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.
