Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located in your rear cargo area, behind the driver's-side and passenger's-side tail lights. You will have to remove the rear floor section and some interior paneling to access this harness.


Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse.


Once installation is complete, the 4-way flat connector will be stowed in your rear cargo area.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


ModuLite Powered Tail Light Converter

A ModuLite power module is built into this T-One connector. Because your vehicle runs on a multiplex wiring system, the wiring needs to be converted to be compatible with the wiring system of your trailer. This power module functions as a tail light converter to combine the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

2019 Volvo XC40

This was a relatively simple and straightforward installation on my 2019 Volvo XC40. The directions were clear, although the black and white pics can be a bit hard to follow. I would add the following points. First, the left plastic rail in the spare tire compartment needs to be removed, and it has an odd hook at the front that is a challenge. It will come with some wiggling. It's equally challenging to put back on. Second, I used the Volvo ground terminal to ground the T-One module. Third, I ran the wire from the module to the positive terminal down through a grommet in the spare tire compartment, then along the brake lines under the car to the battery. This was easy to do with the vehicle on a hoist, but will be more challenging if you don't have access to a hoist. I removed 2 of the protective panels under the car to route the wire. It was fairly straightforward. The product works as advertised and fits very well in the car.

The wiring portion is OK but it's extremely difficult to run the required positive lead wire from the hitch all the way to the vehicle battery. Especially because its under the vehicle needs to be protected from damage & the elements
