It plugs into your vehicle's factory taillight connectors, powers the trailer lights off the battery, and keeps the load off your original wiring. No cutting, no splicing.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Tekonsha 118670 is a T-One connector assembly built around the upgraded circuit-protected ModuLite module. If you're wiring up trailer lights and you'd rather not cut into your factory harness, this is the clean way to do it. The T-One plug drops into your vehicle's existing taillight connectors, and the ModuLite module handles the rest.\u003c\/p\u003e\n\u003cp\u003eHere's what the ModuLite actually does. Instead of pulling trailer-light current straight through your vehicle's circuits, it draws power directly from the battery and uses your taillight signals only to switch the trailer lights on and off. That keeps the load off your factory wiring, which matters when you add a trailer with brighter or more numerous bulbs than the vehicle was designed to feed. The upgraded version adds built-in circuit protection, so a short or an overload at the trailer trips the module instead of frying a fuse or a wire back in the dash.\u003c\/p\u003e\n\u003cp\u003eInstallation is about as friendly as trailer wiring gets. The T-One connectors plug into the matching factory plugs at the rear of the vehicle, no splicing and no scotch-locks. You run a single power lead to the battery for the ModuLite, ground it, and you're done. Most folks knock this out in an afternoon with hand tools.\u003c\/p\u003e\n\u003cp\u003eThe output is a standard 4-way flat trailer connector, which covers basic trailer lighting: running lights, brake lights, and turn signals. That's the right setup for a lot of utility trailers, small boat trailers, and pop-up campers that don't need trailer brakes or a charge line.\u003c\/p\u003e\n\u003cp\u003eOne honest note on fitment. T-One connectors are vehicle-specific, so the plug on this harness is cut for a particular set of factory connectors. Before you order, confirm this 118670 matches your year, make, and model. If you're not sure, send us the vehicle details and we'll check it for you. We'd rather get you the right harness the first time than have you fighting a plug that won't seat.\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 plug-in connectors mate to the vehicle's factory taillight plugs, so there's no cutting or splicing\u003c\/li\u003e\n  \u003cli\u003eCircuit-protected ModuLite module draws trailer-light power from the battery, keeping the load off your factory wiring\u003c\/li\u003e\n  \u003cli\u003eBuilt-in circuit protection trips on a trailer short or overload instead of damaging vehicle wiring\u003c\/li\u003e\n  \u003cli\u003eStandard 4-way flat output covers running lights, brake lights, and turn signals\u003c\/li\u003e\n  \u003cli\u003eSingle power lead to the battery plus a ground completes the install\u003c\/li\u003e\n  \u003cli\u003eVehicle-specific harness for a factory-matched connection at the rear\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\u003eDo I have to cut or splice into my vehicle's wiring?\u003c\/summary\u003e\n    \u003cp\u003eNo. The T-One connectors plug straight into your factory taillight connectors at the rear of the vehicle.
