This Curt T-Connector harness plugs right into the factory tail light connectors, so there’s no need to cut or splice wires. The setup is simple and clean, giving you a 4-pole flat trailer connector ready for towing lights. It’s built as a complete plug-in kit, so you can get it installed quickly and avoid wiring guesswork.
The integrated converter keeps your vehicle’s lighting circuits protected while running your trailer lights. It handles up to 3 amps per circuit for stop/turn functions and 7.5 amps per circuit for running lights. That makes it a solid match for trailers with LED or standard incandescent lights, keeping everything working smoothly without overloads or blown fuses.
The harness is designed to use the vehicle ground for a stable connection, reducing the risk of weak or flickering signals. Proper grounding ensures your brake and turn signals stay bright and consistent even when headlights are on, helping avoid the odd light behavior that can happen with poor trailer grounds.
Each side of the harness uses weather-tight connectors that lock firmly into place behind the tail lights. That tight fit helps prevent corrosion or loose pins that could cause intermittent issues down the road. Once connected, the harness stays out of sight and protected while delivering dependable trailer lighting every time you tow.

This harness grounds through the wiring on the vehicle that the vehicle manufacturer would have run. Youre just supposed to plug the wires in.

the trailer hitch and wiring are both working well for us after about a years use . after having this thing for awhile i find it is just what i needed . i like the fact that when it is not being used the wiring goes in the trunk out of the weather .

When theres an intermittent trailer lamp problem, most of the time it can be traced to a ground problem. Make sure the wiring harness is correctly installed on the vehicle, according to the installation instructions. Make sure the connectors are pushed together until they click. On the trailer, be sure that the ground connection to the trailer frame usually made on the trailer tongue is secure and not corroded. Make sure each lamp is grounded either by its mounting hardware being in direct contact with the trailer fame or by its ground wire being connected to the trailer frame. Ill link you to some help articles that will assist in your troubleshooting.
