Wiring a trailer can be intimidating if it means splicing into the factory lighting, but this harness avoids that altogether. The Curt T-Connector plugs directly into the vehicle’s tail light wiring, giving you a clean 4-pole flat trailer connector without any cutting or soldering. It’s a simple plug-and-play install that lets you get your trailer lights working fast.
Some powered converters require a wire to the vehicle’s battery, but this harness doesn’t. It draws power directly from the taillight circuits, so you don’t have to worry about routing a separate hot lead or finding a place to connect near the battery. That saves time and makes the install much tidier.
The built-in powered converter keeps the vehicle’s electrical system safe by matching the trailer’s wiring signals to the vehicle’s lighting circuits. It ensures proper function for running lights, turn signals, and brake lights without overloading or damaging factory wiring.
The included 4-flat connector covers the essentials—running lights, turn signals, and brake lights—making it ideal for small or mid-size trailers that don’t require electric brakes. Once installed, just plug in your trailer and you’re ready to tow.

Great product. Works great and installation was easy only took about 10 minutes.
No hassle installation, everything just plugged right in.
Product arrived earlier than expected.
Service was great. Knowledge, friendly, helpful.
Product fit was excellence as were the intructions. The no cut wiring is truly plug and play.
All around great online experience.
got this for my Kia Rio. It was delivered quickly and was easy to install. Instructions were good. Only issue I had was with the two sided tape used to secure the module to a flat surface, it was not sticky enough to hold. I got my own tape and secured it, not a big deal, overall happy with this.
I ordered two hitches from trailer and they arrived before there scheduled time with all the instructions. They were easy to install. George J was very helpful with my questions.I would recommend them to anyone asking about a hitch plus they were the cheapest anywhere. Thanks
Excellent ! Was the quickest trailer wiring I ever did. Like plug and play with a computer.
Took longer to reinstall the trim pieces on my Kia Rio. God bless you.
Jesus is our hope for the future !
