It plugs into your factory tow wiring, no cutting or splicing, and gives you a fresh 4-way flat plug for your trailer lights. The clean fix when the original connector gets crushed, corroded, or goes missing.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Tekonsha 118482 is the replacement 4-way flat harness for a vehicle that already has factory tow wiring in place. If your original connector got crushed at the hitch, corroded out, or went missing, this is the clean way to get your trailer lights working again without hacking into the loom.\u003c\/p\u003e\n\u003cp\u003eHere's how it works. The harness plugs straight into your vehicle's existing OEM connectors and gives you a standard 4-way flat plug at the back. No cutting, no splicing, no scotch-locks that fail two seasons later. You're tapping the factory wiring the way the manufacturer intended, so your turn signals, brake lights, and running lights all carry through to the trailer.\u003c\/p\u003e\n\u003cp\u003eA 4-way flat is the light-duty standard. It powers trailer running lights, both turn signals, and the brake lights. That covers most small utility trailers, boat trailers, bike racks with a light bar, and lightweight teardrop campers. What it doesn't do is run electric trailer brakes or a charge line. If your trailer has its own brakes, you're into 7-way territory and you'll want a brake controller too.\u003c\/p\u003e\n\u003cp\u003eTekonsha has been making towing electronics for a long time, and it shows in the small stuff. The connector housings seal against road spray, the terminals resist corrosion, and the wire gauge is matched to the load so you're not chasing dim trailer lights down the road. This is the same style of harness that ships on the factory tow package, not a universal adapter you have to force into place.\u003c\/p\u003e\n\u003cp\u003eOne thing to get right before you order: this is a vehicle-specific replacement. Confirm the 118482 fits your make, model, and year before you buy. If you're not sure, send us your vehicle details and we'll check it against the fitment data. Get the right one and it's a ten-minute job. Locate the factory tow connectors behind a rear trim panel or in the spare tire area, unplug the old harness, click this one in, and route the 4-way flat where you can reach it at the hitch.\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 output powers trailer running lights, turn signals, and brake lights\u003c\/li\u003e\n  \u003cli\u003eT-connector design plugs into your vehicle's factory tow wiring, no cutting or splicing\u003c\/li\u003e\n  \u003cli\u003eDirect replacement for the OEM tow-package harness, matched to your vehicle\u003c\/li\u003e\n  \u003cli\u003eSealed connector housings and corrosion-resistant terminals stand up to road spray\u003c\/li\u003e\n  \u003cli\u003eCorrect wire gauge for the load, so trailer lights stay bright\u003c\/li\u003e\n  \u003cli\u003eVehicle-specific fit, installs in about ten minutes with no tools on most vehicles\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 does a 4-way flat connector power?\u003c\/summary\u003e\n    \u003cp\u003eThe four wires carry your trailer's running lights, left and right turn signals, and brake lights.
