It's the clean way to wire your trailer lights, with no cutting and no splicing into the tow vehicle's harness. The HD module pulls power straight from the battery and keeps a bad trailer circuit from taking your vehicle's wiring down with it.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you tow, you know the weak point is almost always the wiring. The Tekonsha 118784 takes that headache off the table. It's a T-One connector assembly, which means it plugs into your tow vehicle's existing wiring and gives you a standard trailer connector on the other end. No cutting, no splicing, no guessing which wire does what.\u003c\/p\u003e\n\u003cp\u003eThe upgraded piece here is the circuit-protected ModuLite HD module. Instead of running trailer-light current through the tow vehicle's own circuits, the module pulls power directly from the battery and feeds the trailer on its own protected path. So if a trailer bulb shorts out or a connector corrodes, the module absorbs the fault and keeps your vehicle's wiring out of harm's way.\u003c\/p\u003e\n\u003cp\u003eIt's a good match for anyone towing a utility trailer, a boat trailer, or a small camper who wants a plug-in install with real circuit protection behind it. Keep the connector clean and dielectric-greased and this setup will run for years.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eT-One connector assembly plugs into the tow vehicle's existing wiring for a no-splice install\u003c\/li\u003e\n  \u003cli\u003eUpgraded circuit-protected ModuLite HD module isolates the trailer circuit from the vehicle's electrical system\u003c\/li\u003e\n  \u003cli\u003eDraws trailer-light power directly from the battery instead of the vehicle's own light circuits\u003c\/li\u003e\n  \u003cli\u003eCircuit protection shields your tow vehicle's wiring if a trailer light shorts or corrodes\u003c\/li\u003e\n  \u003cli\u003eTekonsha part number 118784 with a plug-in connection for a straightforward hookup\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\u003eDoes the Tekonsha 118784 require cutting or splicing?\u003c\/summary\u003e\n    \u003cp\u003eNo. It's a T-One connector assembly, so it plugs into your tow vehicle's existing wiring and gives you a standard trailer connector on the other end.
