Tekonsha 118727 T-One ModuLite HD, Jeep Grand Cherokee
Tekonsha 118727 T-One ModuLite HD, Jeep Grand Cherokee — Product description
The Tekonsha 118727 T-One connector wires your 2014-2017 Jeep Grand Cherokee for a trailer without any cutting or splicing. Its upgraded ModuLite HD module is a powered, circuit-protected converter that keeps trailer lights bright and shields your Jeep's electronics from shorts and overloads.
The Tekonsha 118727 is a vehicle-specific T-One connector built for the 2014-2017 Jeep Grand Cherokee. It plugs straight into the factory wiring behind your Jeep, so you get trailer lighting without cutting, splicing, or guessing at wire colors. If you've ever fought a universal kit and a test light on a cold driveway, you'll appreciate how clean this one goes in.
What sets this harness apart is the upgraded ModuLite HD module. Instead of tapping the trailer lights directly off your Jeep's circuits, the HD module works as a powered converter. It pulls its load straight from the battery and uses your factory lighting only as a signal. That keeps the trailer's running, brake, and turn signals bright and steady, and it protects the Grand Cherokee's sensitive electronics from the extra draw a loaded trailer can put on them.
Circuit protection is the other big piece. The HD in ModuLite HD means the module is built to shrug off the shorts and overloads that would otherwise blow a fuse or, worse, cook a wire. If a trailer connector gets wet, a bulb shorts, or a ground goes bad out on the road, the module takes the hit instead of your Jeep. That's real peace of mind when you're towing a utility trailer, a small boat, or a pair of kayaks on a flatbed.
The trailer side gives you a standard 4-way flat connector, the most common plug for light-duty trailers. It carries tail lights, brake lights, and turn signals. There's no separate brake-controller circuit here, so it's aimed at trailers without electric brakes. For most weekend loads, a 4-way flat is exactly what you want.
Installation is about as friendly as trailer wiring gets. Find the tow-package connector under the rear of the Jeep, plug the T-One in, mount the module, and route the 4-way flat back to your hitch. No splicing. No scotch locks. It's the kind of job you can knock out in an afternoon and then forget about for years.

Frequently asked questions
Which vehicles does the Tekonsha 118727 fit?
It's a vehicle-specific T-One connector for the 2014-2017 Jeep Grand Cherokee. It plugs into that Jeep's factory tow-package wiring, so it isn't a universal kit.
What does the ModuLite HD module actually do?
It's a powered converter. Instead of tapping trailer lights straight off your Jeep's circuits, it draws the load from the battery and uses your factory lighting as a signal. That keeps trailer lights bright and eases the strain on your Jeep's electronics.
Do I have to cut or splice any wires?
No. The T-One connector plugs directly into the existing wiring behind the Jeep. You mount the module and route the 4-way flat to your hitch. No splicing and no scotch locks.
What kind of trailer plug does it provide?
A standard 4-way flat connector. That carries running lights, brake lights, and turn signals, which covers most light-duty utility trailers, small boat trailers, and kayak trailers.
Why choose the HD module over a plain T-connector?
The HD module adds circuit protection and pulls power from the battery rather than the vehicle's light circuits. If a trailer bulb shorts or a connector gets wet, the module takes the hit instead of your Jeep's wiring, which is why it's the upgraded choice.
Does this support trailer brakes?
No. A 4-way flat connection handles lighting only. If your trailer has electric brakes, you'd need a separate brake-controller setup, so this harness is best for trailers without electric brakes.
