Wiring a trailer often means tapping into factory wires, but this harness skips all that. The CURT T-Connector plugs directly into existing vehicle connections to give you a clean 4-flat trailer plug. No wire cutting, no splicing—just a simple plug-in setup that’s ready to go.
Many vehicles need extra protection when connecting trailer lights. This harness uses a powered converter to draw power directly from the battery instead of the vehicle’s light circuits. It keeps the system safe and ensures your running, turn, and brake lights work consistently every time you tow.
LED trailer lights can sometimes cause flashing or error signals with standard wiring, but not with this harness. The CURT T-Connector is built to handle LED compatibility right out of the box, so you get steady light function without extra adapters or resistors.
The wiring stays tucked away behind trim for a neat look when you’re not towing. When it’s time to hook up the trailer, pull out the 4-flat connector and you’re ready to roll. Once finished, it stores back out of sight—protected from dirt and weather until the next haul.
