Your cart is empty.If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Honda Civic sedan (except hybrid), Honda Fit 5door sport, Honda Accord without LED taillights, Mazda 3, Mazda CX5 and Mitsubishi Galant sedan, 2.4L, single exhaust (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

I bought the CURT 56011 Vehicle-Side Custom 4-Pin Trailer Wiring Harness for my 2011 Honda Fit Sport and installation was a breeze. Really like the no-splice style installation that just plugs in without any fuss. Worked first try and was very easy to hide under the carpet with plenty of extra wire for hooking things up. Great product from a great company.

The harness came as described with decent generic instructions. It was fairly easy to install. However, the product took a long time to receive. There is nothing complex about a simple wiring harness so I suspect Curt is struggling with stocking products or supply chain issues. BTW I ordered the hitch and they messed up the order twice (!) nd I still had to order a missing part. So they have to get their act together.

What I did like was the colour coded wiring and the connectors could only join the correct plug.Half an hour and it was all done.

I recieved the harness in perfect condition in a very timely manor. The written instructions were exacting but the illustrations were really too small for my old eyes. To be sure, I checked the web and there are several videos that confirm the installation technique. The harness installed exactly as stated and fit perfectly.The only drawback I had was that I ordered the hitch and harness for a trip my wife was taking in a few days. She had a borrowed church trailer and when I hooked it up, brake and running lights funtioned but not the turn signals. The trailer was brought to us by an older pickup truck so I reattached the trailer lights to the pickup and everything worked just fine on it, but not on her 2014 Mazda CX5. So with only a few hours before she was to leave, I called Customer service and told them what I had. The call was answered almost immediately and they spent enough time with me on thephone to say it was a totally unusual event and he was sending out a new harness right away. In the few days between calling with a problem and recieving a new harness, I went and acquired a lighted tester since my mulimeter was dead. The harness was functioning perfectly and the trailer was the problem. Now I have to send back the replacement with my apologies for being a doofus. Every aspect of this product is good and I would absolutely recommend or buy again.
