Product Details

Universal 4-Way Flat Connector Socket Kit 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. It features durable rubber-molded construction and is made with standard color-coded, bonded wire. It also includes snap locks, a mounting bracket and all necessary installation hardware to easily splice into your vehicle''s wiring system and mount on the rear of your vehicle. This 4-way flat connector is a female-end socket, specifically designed for the vehicle side of the connection. It is compatible with all 2-wire vehicle systems.

5th wheel hitches are by far the most trouble-free, easiest to hook up, and sweetest-towing rig on the road. Because the hitch is centered over the rear axle instead of four to six feet behind the axle, crosswinds and pavement irregularities that affect the trailer don’t affect the pickup nearly as much. Much like receiver hitches, 5th wheel hitches use an industry-standard rail system so they can be moved to a different truck, or removed temporarily to use the bed for normal hauling.

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.
