It plugs into your Tiguan's factory wiring and gives you a 4-way flat connector on the vehicle side, so you can wire up a small trailer's tail lights, turn signals, and brake lights without cutting a single wire.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you're setting up your 2018-2020 Volkswagen Tiguan to tow, the wiring is usually the part that trips people up. The Tekonsha 118811 takes that worry off the table. It's a custom-fit T-One harness made for this exact vehicle, so the connectors match your Tiguan's factory plugs right out of the box.\u003c\/p\u003e\n\u003cp\u003eHere's how it works. The harness taps into the wiring already running to your Tiguan's tail lights using the factory connectors. No cutting, no splicing, no soldering, and no guessing which wire does what. You route the harness to the back, plug it in, and mount the 4-way flat connector where you can reach it at the hitch. That's the vehicle side of the connection, the part that stays on your tow vehicle. Most folks knock this out in well under an hour with basic hand tools.\u003c\/p\u003e\n\u003cp\u003eThe 4-way flat itself is the most common trailer lighting standard out there. It carries four circuits: taillights, left turn and brake, right turn and brake, and a ground. That's everything a small trailer needs for legal, safe lighting on the road. Think utility trailers, small boat trailers, teardrop campers, or a bike rack with integrated lights.\u003c\/p\u003e\n\u003cp\u003eWhat a 4-way flat doesn't do is run electric trailer brakes or charge a trailer battery. Those need extra circuits, a bigger connector, and a brake controller. So if you're towing something light that just needs lights, this is exactly right. If you've got a heavier trailer with its own brakes, you'll want a larger connector setup instead.\u003c\/p\u003e\n\u003cp\u003eTekonsha has been building towing electronics for a long time, and the T-One line is their plug-and-play answer to modern vehicle wiring. A vehicle-specific harness like this one beats fighting with a universal kit. The fit is clean, the install is quick, and you're not left tracing wires under the dash. And because it's matched to the Tiguan, your factory wiring stays intact, which is nice if you ever sell the vehicle or pull the setup back off. For a Tiguan owner who wants to tow a light trailer without turning it into a weekend project, the 118811 is the straightforward way there.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eCustom-fit T-One harness engineered for the 2018-2020 Volkswagen Tiguan, no universal-kit guesswork\u003c\/li\u003e\n  \u003cli\u003ePlugs into the Tiguan's factory wiring using OEM connectors, so there's no cutting, splicing, or soldering\u003c\/li\u003e\n  \u003cli\u003e4-way flat output powers trailer taillights, left and right turn\/brake signals, and a ground\u003c\/li\u003e\n  \u003cli\u003eVehicle-side harness mounts on the tow vehicle and keeps your factory wiring intact\u003c\/li\u003e\n  \u003cli\u003eIdeal for light trailers that need lighting only, like utility, small boat, or teardrop trailers\u003c\/li\u003e\n  \u003cli\u003eBacked by Tekonsha, a longtime name in towing electronics, with full manufacturer warranty\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 vehicles does the Tekonsha 118811 fit?\u003c\/summary\u003e\n    \u003cp\u003eIt's a custom-fit harness for the 2018-2020 Volkswagen Tiguan.
