Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the rear threshold plate and felt trunk liner 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.
A ModuLite power module is built into this T-One connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are 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.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring. Powered ModuLite reduces strain on wiring system.After a year, and 1,000 mile journey from Florida to Texas, everything still works great for my Corolla. Will definitely be a go-to in the future.
The auto parts store gave me the wrong harness two times, then said that there was no aftermarket one available, that I’d have to get one from the Toyota dealership. With a little googling, I found this one from etrailer, ordered it and it was the right one. Quick shipping too!!
the kit was fine, the work came in trying to get under vehicle to run the 12 volt line to the rear of car, the 2020 corolla is so low too the ground, I soldered the connections then used heat shrink to cover, the rest was easy
T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector from etrailer was a perfect fit. 2020 corolla toke it to a professional shop and they spent more time routin the wires then the actually electrical connections. customer for life. Thanks etrailer
