Trailer wiring can be a pain if you have to splice into factory wires, but this harness skips all that. The Curt T-Connector plugs right into your vehicle’s existing wiring to give you a 4-pole flat trailer connector. No wire cutting, no guesswork—just plug it in and it’s ready to tow.
When towing, consistent lighting is non-negotiable. This harness includes a powered converter that draws power directly from the battery instead of the vehicle’s lighting circuit. That means stable voltage for your trailer lights and protection for your car’s sensitive electronics.
The hidden, plug-in setup keeps wires tucked out of sight and uses factory connection points for a clean finish. You won’t have loose wires hanging under the bumper, and the connector stays protected when not in use.
The 4-flat connector gives you running lights, turn signals, and brake lights—everything you need for pulling small trailers, utility haulers, or cargo carriers. It’s the standard connection for most light-duty towing setups, ready to go when you are.
This will not affect how the tail lights on your vehicle operate.

We do have a help article that explains how to route the power wire of your wiring harness. I have provided a link for your reference.
