A CURT custom wiring harness (also called a T-connector) is a simple, plug-and-play electrical device that eliminates the need for cutting, splicing and soldering when installing vehicle-to-trailer wiring.
Most vehicles do not come ready to tow. Unless your vehicle has a towing package, it is probably not equipped with a trailer wiring connector. This is where CURT''s custom wiring harnesses come into play. Custom wiring harnesses plug into your vehicle''s electrical system using original equipment (OEM) connectors. Our custom wiring harnesses use two or more OEM connectors to plug in at the taillight assembly and provide a standard trailer socket to allow a trailer to be plugged into your vehicle''s power system.
This harness provides a 4-way flat connector socket and comes with a circuit-protected converter. It is designed to be a custom wiring harness for certain years of the Suzuki Grand Vitara SUV (except XL7) or Suzuki SX-4 Sportback (to verify your vehicle compatibility, see the CURT application guide at curtmfg.com). CURT custom wiring harnesses are long-lasting and quick to install. They come with dust covers to keep your connector clean when not in use and feature a one-year limited warranty to give you peace of mind.

Wiring Harness for 2011 Grand Vitara
The instructions for the harness say to install from inside the vehicle, but there is no access due to the plastic trim installed in the back of the vehicle. Had to remove taillights to get access. The connectors are behind the wiring hole and so the wiring for the trailer module have to go though the hole with the grommet. I hope it doesn't wear. Since the wiring has to be on the outside, the lead for the right turn and brake light is too short. I had to splice about a two foot section to get to the right taillight. Even doing all that, it only took about fifteen minutes to get it wired. The only concern I have is the wiring getting worn by the groomets and the short right taillight wire.
