Tekonsha 118599 T-One Harness | 2010-2014 Ford Taurus
Tekonsha 118599 T-One Harness | 2010-2014 Ford Taurus — Product description
Wiring a trailer to a 2010-2014 Ford Taurus doesn't have to mean cutting into your factory harness. The Tekonsha 118599 T-One connector plugs right into the Taurus's existing wiring and adds a circuit-protected ModuLite HD module, so your trailer lights get clean, powered signal without putting the car's electrical system at risk.
The Tekonsha 118599 is a vehicle-specific T-One wiring harness paired with the circuit-protected ModuLite HD module, cut to fit the 2010 through 2014 Ford Taurus four-door. If you're adding a hitch to your Taurus and need to run trailer lights, this is the wiring side of that job done right.
Here's what makes the T-One connector easy to work with. It plugs directly into your Taurus's existing wiring at the factory connector. No cutting, no splicing, no scotch-locks tapping into your brake and turn signal wires. You find the vehicle's harness, unplug it, plug the T-One in between, and route the trailer connector to the back. Most folks get it done in under an hour.
The ModuLite HD module is where the smart part lives. Instead of pulling trailer-light current straight through your car's circuits, it draws power directly from the battery and uses the vehicle's signals only to switch the lights. That keeps a trailer short or an overloaded bulb from frying a fuse or a control module in your Taurus. It's circuit protected and self-resetting, so a momentary overload won't leave you stranded with dead trailer lights.
The output is a standard 4-way flat connector, which is what most small trailers, utility trailers, and boat trailers run for their running lights, brakes, and turn signals. If your trailer already has a 4-flat plug, you're plug-and-go once the harness is in. If it doesn't, a simple 4-flat adapter gets you there.
One thing to be clear on. This is the wiring and lighting-power side of towing. It doesn't run electric trailer brakes on its own, and it's cut for the Taurus specifically, so it won't be the right harness for a different vehicle. If you're towing something with electric brakes, or you drive a different car, let us know and we'll point you to the right Tekonsha part.

Frequently asked questions
Which vehicles does the 118599 fit?
It's cut specifically for the 2010 through 2014 Ford Taurus four-door. It plugs into that vehicle's factory wiring connector, so it won't be the right harness for a different make or model. If you drive something else, check with us before ordering.
Do I have to cut into my factory wiring?
No. That's the whole point of the T-One connector. It plugs in between your Taurus's existing harness connectors, so there's no splicing, no scotch-locks, and nothing tapped into your brake or turn signal wires.
What does the ModuLite HD module actually do?
It's a powered converter. Rather than pulling trailer-light current through your car's circuits, it draws power straight from the battery and uses the vehicle's signals only to switch the lights. That protects your Taurus's electrical system from a trailer short or an overloaded bulb.
What kind of trailer connector does it use?
A standard 4-way flat. That covers running lights, brake lights, and turn signals on most small trailers, utility trailers, and boat trailers. If your trailer has a 4-flat plug already, you're ready to go.
Will this run electric trailer brakes?
No. This handles trailer lighting, not electric brakes. If you're towing a trailer with electric brakes, you'll also need a brake controller. Let us know what you're towing and we'll help you sort the right setup.
Is the module protected if something shorts out?
Yes. The ModuLite HD is circuit protected and self-resetting. A momentary overload trips it rather than blowing a fuse, and it recovers on its own once the fault clears.
