Tekonsha 118764 T-One ModuLite HD Wiring, Ford Focus
Tekonsha 118764 T-One ModuLite HD Wiring, Ford Focus — Product description
The Tekonsha 118764 T-One connector is a plug-in trailer wiring harness built for the Ford Focus. It drops in behind the factory wiring with no cutting or splicing, and its circuit-protected ModuLite HD module pulls power straight from the battery to run your trailer lights while shielding the Focus electrical system from shorts and overloads.
The Tekonsha 118764 is a T-One connector assembly made to wire a Ford Focus for towing. It's a vehicle-specific harness, so it plugs right into the factory wiring behind your taillights. No cutting, no splicing, no guessing which wire does what. If you've ever taped up a butchered wiring job on the side of the road, you'll appreciate how clean this one goes in.
The heart of it is the upgraded ModuLite HD module. Instead of pulling trailer power off your Focus taillight circuits, the ModuLite draws current straight from the battery. Your factory bulbs stay on their own circuit, and the trailer lights run off their own feed. That matters because it keeps the extra load of a trailer off the delicate lighting circuits and body control modules that modern cars lean on. The HD module is circuit protected too, so a short in the trailer harness or a corroded connector trips the protection instead of frying something expensive under the dash.
Out the back you get a standard 4-way flat connector. That's everything you need for running lights, brake lights, and turn signals on a basic utility trailer, a bike rack with lights, or a light boat trailer. Plug the module in, mount the 4-flat where you can reach it, and you're towing.
Who's this for? Focus owners who want a factory-clean tow setup without hacking into the wiring. It's honest, no-nonsense towing wiring from a company that's built trailer brake and lighting gear for a long time. One thing to know up front. This is a 4-flat lighting harness. It doesn't carry electric trailer brakes or a 12V charge line on its own, so if you're towing something heavy with brakes, you'll want a brake controller and a heavier connector on top of this. For lights on a modest trailer behind a Focus, though, it's exactly right.

Frequently asked questions
What vehicle does the Tekonsha 118764 fit?
It's a T-One connector assembly built specifically for the Ford Focus. It plugs into the Focus factory wiring behind the taillights, so it's a direct fit for that vehicle rather than a universal harness.
Do I have to cut or splice any wires to install it?
No. The T-One design plugs into your existing factory connectors. You mount the ModuLite HD module, route the 4-flat to the back, and you're done. No splicing or wire cutting.
What does the ModuLite HD module do?
The ModuLite HD is a powered converter. Instead of tapping trailer power from your taillight circuits, it pulls current directly from the battery. That keeps the trailer's electrical load off the Focus factory lighting circuits and adds circuit protection against shorts.
What kind of trailer connector does it provide?
A standard 4-way flat connector. That covers running lights, brake lights, and turn signals for a basic utility trailer or a light boat trailer.
Does this harness power electric trailer brakes?
No. This is a 4-flat lighting harness. It handles trailer lights but doesn't run electric brakes or a charge line on its own. If your trailer has electric brakes, you'll also need a brake controller and a heavier connector.
Is the module circuit protected?
Yes. The upgraded ModuLite HD module has built-in circuit protection, so a short or overload in the trailer wiring trips the protection instead of damaging the vehicle's electrical system.
