Tekonsha 118628 T-One Harness w/ ModuLite HD Module
Tekonsha 118628 T-One Harness w/ ModuLite HD Module — Product description
The Tekonsha 118628 is a custom-fit T-One wiring harness paired with a circuit-protected ModuLite HD module, built to add trailer wiring to a 2014 Acura MDX. It plugs straight into your factory harness, so there's no cutting and no splicing. The ModuLite HD pulls power from the battery to run your trailer lights and keep the MDX's electrical system protected.
If you're rigging up a 2014 Acura MDX to pull a small utility trailer, a bike rack with lights, or a teardrop camper, the Tekonsha 118628 is the clean way to do it. It's a custom-fit T-One connector, which means the harness plugs directly into the wiring your MDX already has behind the rear panel. No cutting into factory wires. No splicing. No scotch-locks that corrode a season later. You find the vehicle's connector, plug this one in line, and you're most of the way there.
What sets this kit apart from a basic tap-in is the ModuLite HD module. Instead of pulling trailer-light power through your vehicle's circuits, the module draws power straight from the battery. Your MDX's wiring only sends the signal, telling the module when to fire the brake lights, the turn signals, and the running lights. That keeps the trailer's electrical load off the factory system, which helps protect the vehicle's bulb-out sensors and body control module from the extra draw. The HD version adds circuit protection, so a short in the trailer wiring won't take out anything on the tow vehicle.
The output is a standard 4-way flat connector, the common trailer plug for running lights, left and right turn or brake, and a ground. That covers most small utility trailers, boat trailers, and light campers. If your trailer already wears a 4-flat, you'll plug right in.
Install is straightforward for anyone comfortable pulling a rear trim panel. The connectors are vehicle-specific, so the plugs only fit one way. Mount the module somewhere dry, route the 4-flat out to where you need it, and ground it to clean metal. Most folks have this done in under an hour. And if you've never done trailer wiring before, it's a friendly first job, because there's nothing to splice.
One honest note. This harness is built for the 2014 Acura MDX. Tekonsha makes T-One connectors for hundreds of vehicles, so if your MDX is a different year, check the fitment before you buy. Get the right one, though, and you've got factory-clean trailer wiring that'll outlast the trailer.

Frequently asked questions
Does the 118628 fit my Acura MDX?
This harness is built specifically for the 2014 Acura MDX. Tekonsha makes T-One connectors for many other years and models, so if your MDX is a different year, confirm the fitment before ordering.
Do I have to cut or splice any wires?
No. The T-One connector plugs directly into the factory wiring, so there's no cutting, splicing, or scotch-locks. The vehicle-specific plugs only fit one way.
What does the ModuLite HD module actually do?
It powers your trailer lights using power drawn straight from the battery, while your vehicle's wiring just sends the on and off signal. That keeps the trailer's electrical load off the factory circuits and helps protect sensitive vehicle electronics.
What kind of trailer connector does it provide?
It provides a standard 4-way flat connector, which handles running lights, left and right turn or brake, and a ground. That covers most small trailers.
Why choose the HD module over a basic converter?
The HD module adds circuit protection. If the trailer wiring shorts out, that protection keeps the fault from reaching the tow vehicle's electrical system.
Is this hard to install?
If you're comfortable removing a rear trim panel, it's a straightforward job. Plug in the connector, mount the module in a dry spot, route the 4-flat, and ground it to clean metal. Most installs take under an hour.
