If your vehicle already has the factory tow package, this harness makes adding trailer lighting simple. The Curt T-Connector Vehicle Wiring Harness for Factory Tow Package – 4-Pole Flat Trailer Connector (part #C56293) plugs right into the existing ports. There’s no need to cut or splice wires, so you get a clean hookup without guesswork.
Once connected, the 4-pole flat plug gives you lighting functions for running, brake, and turn signals. It’s the basic, reliable setup for most small and medium trailers—ready to plug straight into your trailer’s wiring.
The harness tucks neatly out of sight, blending in with the vehicle’s factory wiring. That hidden, plug-in design keeps everything secure and protected from road grime while maintaining an OEM look.
Curt builds this harness with weather-resistant connectors and durable wiring for consistent signal delivery. Once installed, it stays put and performs as expected mile after mile, giving you dependable trailer lighting whenever you tow.

Perfect fit. Easy installation!
It does the job, never had a problem with it.
these folk always do a great job
The attention was great, but unfortunately I received the wrong part
Thank you so much for solving the issue I had - the product arrived just on time as I was going to p/u my new wave runner/trailer!!!!
I'd recommend ETrailer.com to anyone that has trailer and trailer accessory needs!!!
Very easy to install if your car has the wiring already done. It works great!
Huge savings over the factory dealer option that wanted $300 for the part and $400 for the install.
I ordered a light kit for a Range Rover. The order arrived promptly. The instructions were easy to follow and I was able to install it in about 5 minutes. I saved $60 by ordering it from etrailer and installing it myself!
Package arrived on time and was exactly as described. Installation instructions were simple and easy. Will definitely use etrailer again.
I am extremely pleased with your product. It was exactly as advertised and worked as explained. All lights worked. The dealership examined my vehicle and said I needed $429 worth of work to get lights to work. Your modestly priced product worked perfectly. I am most disappointed in such a reputable dealership being willing to knowingly rip off their customers. I will NEVER do business with that dealership again. Thank you for your standard and integrity.
Etrailer is truly one of the best online retailer that I have dealt with. Their customer service is phenomenal. I requested wiring advice for an install to my Range Rover on a Saturday evening and on Sunday afternoon I received an email outlining everything I needed for my current application as well as part numbers for future possibilities. Their prices are great and when you order you promptly get an acknowledgement and thank you. Tracking numbers were received the next day when my harness shipped. All this for a $14 dollar order. I am looking foreword to doing some real business with Etrailer. Service like this deserves the business.
I've bought from etailer actually 4 or 5 times in the past. Each time the quality was spot on in the installation was as the videos. Would buy again if needed.

Working great after a year. No issues. Wiring harness was perfect for my vehicle.
Very easy to install. Plug in play.
This equipment works as designed. I needed to have towing lights added to my 2014 Range Rover Sport. I saw an e-trailer you tube video showing this kit and how to install it. It was a breeze. I would recommend if you have this need.
