It plugs straight into your factory harness, so there's no cutting and no splicing. The ModuLite HD pulls power from the battery to run your trailer lights and keep the MDX's electrical system protected.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you're rigging up a 2014 Acura MDX to pull a small utility trailer, a bike rack with lights, or a teardrop camper, the Tekonsha 118628 is the clean way to do it. It's a custom-fit T-One connector, which means the harness plugs directly into the wiring your MDX already has behind the rear panel. No cutting into factory wires. No splicing. No scotch-locks that corrode a season later. You find the vehicle's connector, plug this one in line, and you're most of the way there.\u003c\/p\u003e\n\u003cp\u003eWhat sets this kit apart from a basic tap-in is the ModuLite HD module. Instead of pulling trailer-light power through your vehicle's circuits, the module draws power straight from the battery. Your MDX's wiring only sends the signal, telling the module when to fire the brake lights, the turn signals, and the running lights. That keeps the trailer's electrical load off the factory system, which helps protect the vehicle's bulb-out sensors and body control module from the extra draw. The HD version adds circuit protection, so a short in the trailer wiring won't take out anything on the tow vehicle.\u003c\/p\u003e\n\u003cp\u003eThe output is a standard 4-way flat connector, the common trailer plug for running lights, left and right turn or brake, and a ground. That covers most small utility trailers, boat trailers, and light campers. If your trailer already wears a 4-flat, you'll plug right in.\u003c\/p\u003e\n\u003cp\u003eInstall is straightforward for anyone comfortable pulling a rear trim panel. The connectors are vehicle-specific, so the plugs only fit one way. Mount the module somewhere dry, route the 4-flat out to where you need it, and ground it to clean metal. Most folks have this done in under an hour. And if you've never done trailer wiring before, it's a friendly first job, because there's nothing to splice.\u003c\/p\u003e\n\u003cp\u003eOne honest note. This harness is built for the 2014 Acura MDX. Tekonsha makes T-One connectors for hundreds of vehicles, so if your MDX is a different year, check the fitment before you buy. Get the right one, though, and you've got factory-clean trailer wiring that'll outlast the trailer.\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 connector for the 2014 Acura MDX plugs into the factory harness with no cutting or splicing\u003c\/li\u003e\n  \u003cli\u003eCircuit-protected ModuLite HD module draws trailer-light power straight from the battery, keeping the load off your vehicle's electrical system\u003c\/li\u003e\n  \u003cli\u003eBuilt-in circuit protection shields the tow vehicle if the trailer wiring shorts out\u003c\/li\u003e\n  \u003cli\u003eStandard 4-way flat output connects to most small utility, boat, and camper trailers\u003c\/li\u003e\n  \u003cli\u003eVehicle-specific plugs fit one way only, so there's no guessing during install\u003c\/li\u003e\n  \u003cli\u003ePowers running lights, turn signals, and brake lights through a dedicated module instead of the factory circuits\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 118628 fit my Acura MDX?\u003c\/summary\u003e\n    \u003cp\u003eThis harness is built specifically for the 2014 Acura MDX.
