Wiring a trailer usually means tracking down the right wires and making splices, but this harness skips all that. The Curt T-Connector plugs directly into the existing tail light wiring to create a 4-pole flat trailer connector. There’s no wire cutting or guessing—just plug it in and it’s ready to go.
When a vehicle has separate turn and brake light circuits, this harness’s built-in converter takes care of the difference so the trailer lights work correctly. It combines the signals automatically to match a trailer’s shared turn/brake setup, giving you the right lighting every time without extra wiring work.
The harness uses hidden, factory connection points to keep everything neat and out of sight. The plug-and-lead design routes cleanly behind trim panels, protecting the wires from dirt and damage while keeping the rear area tidy.
The 4-flat connector provides all the standard functions—running lights, left and right turn signals, and brake lights. It’s the most common connector type for small and mid-size trailers and ensures a consistent, reliable connection whenever you tow.

The yellow T goes behind the driver tail light and picks up the left turn and running light signal. The green T goes behind the passenger tail light and picks up right turn and the brake light signal. See step 5 in the instructions.

Not only are they awesome my second time purchasing as I bought a new car and needed a new hitch bar I highly recommended you guys to people on Reddit home improvement sub! A lot a people didn’t realize how easy it is to install a hitch onto a car and pull a tag along trailer for east home improvement stuff pick ups. So many were thinking they’d need to purchase a truck just to haul things. I recommended your site because if it’s easy to use ordering and videos to watch the simple installs. Thank you for your company and it’s great service!
