Tekonsha 118834 T-One ModuLite HD, Hyundai Elantra
Tekonsha 118834 T-One ModuLite HD, Hyundai Elantra — Product description
The Tekonsha 118834 wires your Hyundai Elantra for a trailer without cutting into the factory harness. It's a plug-in T-One connector paired with the circuit-protected ModuLite HD module, so the trailer lights pull power from the battery instead of loading down the car's own wiring.
If you're rigging a Hyundai Elantra to pull a small trailer, a bike rack with lights, or a teardrop camper, the Tekonsha 118834 is the clean way to do it. It's a vehicle-specific T-One connector, which means it plugs straight into the wiring already behind your Elantra's rear panels. No cutting, no splicing, no scotch-locks hanging off your taillight wires.
What sets this one apart from a bare T-connector is the ModuLite HD module that comes with it. On a lot of newer cars, the factory wiring just can't handle the extra draw of trailer lights, and a hard-wired connector can trip the car's bulb-out warnings or overload a circuit. The ModuLite HD gets around that. It pulls power straight from the battery to run the trailer lights, so your Elantra's own circuits only send the low-current signal. The car's electronics stay happy.
The module is circuit protected, so a short at the trailer, a pinched wire, a corroded connector, won't feed back and cook your car's wiring. That protection is the whole point of the HD upgrade. The output is a standard 4-way flat, which covers running lights, brake lights, and both turn signals on most utility trailers, small campers, and light-duty haulers.
Install is about as friendly as trailer wiring gets. You find the factory connector Tekonsha designed this to mate with, plug the T-One in line, mount the module, and route the 4-way flat out to your hitch. Most folks get it done in an afternoon with hand tools. And because it plugs into the existing harness, you're not voiding anything or leaving a mess of taped splices to corrode over a couple of seasons.
One honest note: this kit is built specifically for the Hyundai Elantra. If you've got a different vehicle, you'll want the T-One matched to your car so the connector actually plugs in. Not sure which one fits your ride? Give us a shout and we'll point you to the right part number.

Frequently asked questions
What vehicle does the 118834 fit?
It's built specifically for the Hyundai Elantra. The T-One connector is shaped to plug into the Elantra's factory wiring. If you have a different vehicle, check with us so we can match you to the right part number.
What is the ModuLite HD module for?
It's a powered converter that runs your trailer lights off the vehicle battery instead of loading down the car's factory wiring. That keeps the Elantra's circuits from getting overloaded and avoids tripping bulb-out warnings.
Do I have to cut any wires to install it?
No. The T-One connector plugs directly into the existing factory connector behind the rear panels. No splicing, no scotch-locks. You mount the module and route the 4-way flat out to the hitch.
What kind of trailer plug does it give me?
A standard 4-way flat. That covers running lights, brake lights, and both turn signals on most utility trailers, small campers, and light-duty haulers.
Will it work with LED trailer lights?
Yes. The ModuLite HD module powers both LED and incandescent trailer lights.
What does circuit protected mean here?
If something shorts out at the trailer, a pinched wire or a corroded connector, the module blocks that fault from feeding back into your Elantra's wiring. It protects the car, which is the reason to run the HD module over a bare connector.
