This harness uses a powered converter that connects directly to the vehicle battery. That setup keeps the trailer lights from drawing power through sensitive factory wiring. Running the hot lead up to the positive post in the engine bay gives the converter a clean, reliable power source and keeps everything working properly.
Installing trailer wiring usually means cutting into factory wires, but this T-Connector skips that mess. It plugs right into existing connectors, so you don’t have to splice or guess which wire does what. Just snap the plugs in place and route the 4-flat lead to the back.
The built-in 4-pole flat connector gives you running, turn, and brake light circuits for standard trailers. It’s the common hookup for small utility, boat, and cargo trailers, so once it’s connected you’re ready to tow safely.
The plug-in harness tucks neatly out of sight thanks to its hidden plug-and-lead layout. It uses existing trim paths and grommet points for a tidy finish with no loose wires hanging under the bumper.
