It plugs straight into the factory tow connector behind the bumper and gives you clean, reliable lighting for utility trailers, small boat trailers, and bike racks. Matched to the vehicle, so the fit is right the first time.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Tekonsha 118501 is a T-One vehicle wiring harness that gives your 2011 Hyundai Tucson a clean 4-way flat trailer connector without cutting into the factory wiring. It plugs into the connectors already behind your rear bumper, so the towing circuits tie in the way the vehicle was built to handle them. No splicing. No scotch-locks. No guessing which wire does what.\u003c\/p\u003e\n\u003cp\u003eA 4-way flat carries the basics every small trailer needs. Running and tail lights, left turn and brake, right turn and brake, and a ground. That covers most utility trailers, small boat trailers, popup campers, and bike racks that run their own lighting. If you're pulling a light load behind the Tucson and just need the lights to work, this is the connector that does it.\u003c\/p\u003e\n\u003cp\u003eInstall is about as simple as trailer wiring gets on a modern crossover. You'll find the factory tow connector in the driver-side rear area, unplug the cover, and seat the harness in its place. The 4-flat then routes out to where you'll reach it at the hitch. Most folks have it done in well under an hour with basic hand tools, and there's nothing to program or calibrate afterward.\u003c\/p\u003e\n\u003cp\u003eA few honest notes. This is a lighting connector, not a brake control. It won't power electric trailer brakes and it doesn't add a charge line for a trailer battery. If your trailer needs those, you're looking at a different setup. But for standard 4-flat trailers, the T-One approach is the cleanest way to wire a Tucson, and because it's matched to the vehicle, the fit is right the first time.\u003c\/p\u003e\n\u003cp\u003eTekonsha has built towing electronics for a long time, and the T-One line is their take on plug-and-play trailer wiring. You get a factory-style connection that seats where the engineers intended, a 4-flat that's ready to hook up at the hitch, and a connector that tucks out of the way when you're not towing. For a weekend of hauling the boat or the utility trailer, that's exactly what you want.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e4-way flat connector: powers running, tail, and turn\/brake lights on standard small trailers\u003c\/li\u003e\n  \u003cli\u003eT-One plug-in design: ties into the factory tow connector with no splicing or scotch-locks\u003c\/li\u003e\n  \u003cli\u003eVehicle-specific fit for the 2011 Hyundai Tucson: matched to the OEM wiring so the connection is right the first time\u003c\/li\u003e\n  \u003cli\u003eReplaces the OEM wiring harness section behind the bumper for a clean, factory-style installation\u003c\/li\u003e\n  \u003cli\u003eInstalls in under an hour with basic hand tools: nothing to program or calibrate\u003c\/li\u003e\n  \u003cli\u003eConnector stows out of the way when you're not towing to keep the rear of the Tucson tidy\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Tekonsha reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat vehicle does the Tekonsha 118501 fit?\u003c\/summary\u003e\n    \u003cp\u003eIt's a T-One harness matched to the 2011 Hyundai Tucson.
