Tekonsha 118669 T-One Connector with ModuLite Module
Tekonsha 118669 T-One Connector with ModuLite Module — Product description
Towing a small trailer and don't want to splice into your factory wiring? The Tekonsha T-One Connector Assembly makes it a plug-in job. It pairs a T-connector that snaps into your vehicle's existing harness with an upgraded, circuit-protected ModuLite module that pulls trailer-light power straight from the battery, so your car's wiring never carries the load.
The Tekonsha T-One Connector Assembly is a plug-and-play trailer wiring harness. The T-connector plugs into your tow vehicle's existing wiring using the factory-style connector, so there's no cutting, no splicing, and no tapping into your brake or tail light wires. Out the other end you get a standard 4-way flat trailer connector, ready to run your trailer's lights.
What sets this assembly apart is the upgraded, circuit-protected ModuLite module. Instead of borrowing power from your vehicle's turn signal and brake circuits, the ModuLite pulls power directly from the battery to run the trailer lights. Your vehicle's electrical system just sends the signal, and the module does the heavy lifting. That keeps the trailer-light load off your car's computer and wiring, which matters a lot on newer vehicles with sensitive lighting circuits.
The circuit protection is the other half of the story. A short or an overload on the trailer side won't take out your vehicle's lighting circuits. The module absorbs the trouble instead of passing it back to the car. It's a simple safeguard, but it's the kind of thing you're glad is there the first time a trailer connector gets wet or pinched.
This is the harness for anyone towing a small utility trailer, a boat trailer, a popup camper, or a bike rack that needs lighting on the standard 4-way flat connector. Because the T-connector is vehicle-specific, confirm this part number matches your make, model, and year before you order. Send us your vehicle details and we'll double-check the fit for you.
Install is about as easy as trailer wiring gets. Find your vehicle's harness connector, usually near the taillight or behind a rear trim panel, unplug it, and plug the T-One in between. Mount the ModuLite module, route the 4-way flat to the rear, and you're done. Most folks knock it out in under an hour with basic hand tools.

Frequently asked questions
Do I have to cut or splice any wires?
No. The T-One connector plugs into your vehicle's existing wiring harness using the factory-style connector. No cutting, no splicing, and no tapping into your brake or tail light wires.
What does the ModuLite module actually do?
It's a powered converter. Instead of drawing trailer-light power through your vehicle's turn and brake circuits, it pulls power straight from the battery. Your vehicle just sends the signal, which keeps the extra load off your car's wiring and computer.
What kind of trailer connector does this give me?
A standard 4-way flat. That's the common connector for running taillights, turn signals, and brake-light signals on smaller trailers, boat trailers, and popup campers.
Will this fit my vehicle?
The T-One connector is vehicle-specific, so confirm this exact part number matches your make, model, and year before ordering. Send us your vehicle details and we'll check the fit for you.
What does circuit-protected mean here?
The module has built-in circuit protection, so a short or an overload on the trailer side won't blow your vehicle's lighting circuits. It's a safeguard for your car's electrical system.
Does it handle electric trailer brakes?
No, this is a lighting connector. A 4-way flat carries running lights, turn signals, and brake-light signals, but not electric trailer brakes. For electric brakes you'd need a brake controller and a different connector.
How long does installation take?
Most people get it done in under an hour with basic hand tools. Locate the harness connector, plug the T-One in, mount the module, and route the 4-way flat to the rear.
