{"product_id":"tekonsha-118269-modulite-hd-4-way-flat-harness","title":"Tekonsha 118269 ModuLite HD 4-Way Flat Harness","description":"\u003cp class=\"nvn-hero\"\u003eThe Tekonsha 118269 is a 4-way flat replacement towing harness built around Tekonsha's Circuit Protected ModuLite HD module. It's a powered converter, so your trailer lights run off a separate supply instead of loading your vehicle's factory wiring. You get tail, brake, and turn signals at a standard 4-way flat plug, with built-in circuit protection keeping faults out of your truck.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you're wiring up a trailer and want to keep your tow vehicle's factory electrical system out of harm's way, the Tekonsha 118269 is built for exactly that. It's a 4-way flat replacement harness that carries Tekonsha's Circuit Protected ModuLite HD module, so your trailer's lights pull power the smart way instead of loading down your vehicle's original wiring.\u003c\/p\u003e\n\u003cp\u003eHere's what makes the ModuLite HD different from a plain splice-in converter. It's a powered module. Instead of drawing current for your trailer lamps straight through the vehicle's circuits, it pulls that power separately and switches it based on your turn, brake, and running-light signals. That keeps the load off your factory harness and off the sensitive control modules that don't like extra draw. And if a bulb shorts out or a trailer plug gets wet and faults, the built-in circuit protection steps in instead of letting the trouble travel back into the truck.\u003c\/p\u003e\n\u003cp\u003eThis one is designed to replace the OEM towing harness rather than tap into it, so you're connecting a clean, purpose-built assembly that finishes at a standard 4-way flat connector. That 4-way flat is the workhorse fitting for utility trailers, small boat trailers, landscape trailers, and most single-axle setups. Left turn, right turn, brake, and tail, all in one plug your trailer already knows how to talk to.\u003c\/p\u003e\n\u003cp\u003eFitment is application-specific, so check that the 118269 is the right harness for your year, make, and model before you order. Once it's the correct part, the install is straightforward. Route the harness, make your connections, mount the module somewhere dry and protected, and you're ready to plug in. We stock a lot of Tekonsha towing gear and we've wired up more trailers than we can count. So if you're not sure this is the right harness for your rig, ask us before you buy and we'll point you at the correct part.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eCircuit Protected ModuLite HD module: powered converter that runs trailer lights off a separate supply and shields your vehicle's factory wiring from overloads and shorts.\u003c\/li\u003e\n  \u003cli\u003e4-way flat output connector: the standard trailer fitting for tail, brake, and left and right turn signals on utility, boat, and single-axle trailers.\u003c\/li\u003e\n  \u003cli\u003eOEM harness replacement design: installs in place of the factory towing harness instead of splicing into your original vehicle wiring.\u003c\/li\u003e\n  \u003cli\u003ePowered switching: the module carries the lighting load so your vehicle's control modules and fuses aren't stressed by the trailer.\u003c\/li\u003e\n  \u003cli\u003eGenuine Tekonsha part 118269: from the industry leader in trailer brake controls and towing electrical gear.\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 the ModuLite HD module actually do?\u003c\/summary\u003e\n    \u003cp\u003eIt's a powered converter.
