Tekonsha 118773 T-One Harness for 2018 Volvo XC60
Tekonsha 118773 T-One Harness for 2018 Volvo XC60 — Product description
The Tekonsha 118773 T-One connector wires your 2018 Volvo XC60 for towing without cutting a single factory wire. It plugs straight into the vehicle harness and adds a circuit-protected ModuLite HD module, giving you a clean 4-way flat trailer connector for running lights, turn signals, and brakes.
If you own a 2018 Volvo XC60 and you want to tow a small trailer, a utility trailer, or a lightweight camper, this is the wiring you're after. The Tekonsha 118773 is a vehicle-specific T-One connector built to plug directly into the XC60's factory towing harness. No splicing, no scotch-locks, no guessing which wire is the left turn signal. You find the plug, you connect it, and you route the 4-way flat out to the back.
What sets this kit apart from a bare T-connector is the upgraded circuit-protected ModuLite HD module. Here's why that matters. The ModuLite HD is a powered converter. Instead of pulling all of its current straight off the vehicle's tail-light circuit, it draws power directly from the battery and uses the vehicle signals only to tell the trailer lights when to fire. That keeps the load off the Volvo's sensitive lighting electronics, which is exactly what you want on a newer vehicle with CAN-bus wiring and bulb-out monitoring.
The module is circuit protected, so a short or an overload at the trailer end trips the protection instead of frying the converter or the vehicle harness. It also handles both LED and incandescent trailer lights without complaining. That's handy because a lot of newer trailers run LED tail lights that can confuse a simpler converter.
You get a standard 4-way flat output at the trailer side. That covers running and tail lights, left turn and brake, and right turn and brake. It's the most common trailer connector on the road, so it'll match most utility trailers, small boat trailers, and lightweight campers right out of the box. If your trailer runs a different plug, a cheap adapter gets you there.
Installation is about as friendly as trailer wiring gets. Everything is plug-in and vehicle-specific to the 2018 XC60, so most folks have it done in well under an hour with basic hand tools. Mount the module in a protected spot, run the harness to the rear, and you're ready to hook up. If you're not comfortable working around the vehicle's wiring, any trailer shop can install it quickly. And that's the whole point. Get set up right the first time so your lights work every time you hitch up.

Frequently asked questions
What vehicle does the Tekonsha 118773 fit?
It's a vehicle-specific T-One connector built for the 2018 Volvo XC60. The harness plugs directly into the XC60's factory towing wiring, so there's no cutting or splicing required.
What is the ModuLite HD module and why does it matter?
The ModuLite HD is a powered converter. It draws current directly from the battery and uses the vehicle's light signals only to tell the trailer lights when to turn on. That keeps the electrical load off the Volvo's sensitive lighting circuits, which is important on a newer vehicle with bulb-out monitoring.
What kind of trailer connector does it provide?
You get a standard 4-way flat output. That handles running and tail lights, left turn and brake, and right turn and brake, which covers most utility trailers, small boat trailers, and lightweight campers.
Will it work with LED trailer lights?
Yes. The circuit-protected ModuLite HD module is designed to run both LED and incandescent trailer lights, so it works whether your trailer has modern LED lamps or older bulbs.
Do I need to cut any factory wires to install it?
No. This is a plug-in T-One connector matched to the 2018 XC60. You locate the factory tow plug, connect the harness, mount the module in a protected spot, and route the 4-way flat to the rear. No splicing needed.
Is the module circuit protected?
Yes. If there's a short or an overload at the trailer, the built-in circuit protection trips instead of damaging the converter or the vehicle harness.
