Tekonsha 118757 T-One Connector + ModuLite HD Module
Tekonsha 118757 T-One Connector + ModuLite HD Module — Product description
The Tekonsha 118757 pairs a T-One connector assembly with an upgraded, circuit-protected ModuLite HD module. It's a clean way to add trailer wiring to your tow vehicle without cutting into the factory harness, and the heavy-duty module keeps your vehicle's electrical system protected while you tow.
If you're wiring up a trailer and want to keep things simple, the Tekonsha 118757 is a solid pick. It combines a T-One connector assembly with an upgraded ModuLite HD module, so you get a plug-in connection plus a heavy-duty power converter in one kit. No splicing into your tow vehicle's factory wiring and no guesswork.
The ModuLite HD part is what sets this one apart. It's a circuit-protected, powered converter that draws trailer lighting power straight from the battery instead of pulling it through your vehicle's existing circuits. That means brighter, more reliable trailer lights and built-in protection for your truck or SUV's electrical system. If there's an overload or a short at the trailer, the circuit protection does its job.
This is the gear you want for towing boats, utility trailers, or campers where you need dependable lighting trip after trip. It's a Tekonsha part, so it's built to the same standard the brand is known for in trailer wiring and brake control.

Frequently asked questions
What's included with the Tekonsha 118757?
It's a T-One connector assembly paired with an upgraded, circuit-protected ModuLite HD module. You get the plug-in connector and the powered converter module together in one kit.
What does the ModuLite HD module do?
It's a powered converter that pulls trailer lighting power from the battery rather than the vehicle's existing circuits. That gives you brighter, steadier trailer lights and keeps your tow vehicle's electrical system protected.
What does circuit protected mean here?
The module has built-in protection, so if the trailer side sees a short or an overload, the circuit protection steps in instead of letting the fault reach your vehicle's wiring.
