Wiring up a trailer can be a hassle if you have to trace and cut into factory wires. The Curt T-Connector harness makes it simple with plug-and-play connectors that fit inline with your existing tail light wiring. Just plug the ends in place and route the powered converter wire—no splicing or complicated wiring required.
This harness includes a powered converter that draws power directly from the vehicle battery rather than through the lighting circuits. That setup keeps your vehicle’s sensitive electronics safe from overload and ensures you get a full 12 volts at the 4-way output when the appropriate taillight signal is activated. It’s a reliable way to run trailer lights on vehicles with complex wiring systems.
The 4-flat connector delivers the essential lighting functions—running lights, turn signals, and brake lights—to your trailer. It’s the standard hookup for small to mid-size trailers and works as a base connection if you ever later add a 7-way or brake controller using an additional kit.
If you decide later to tow a trailer with electric brakes or need a charging circuit, this 4-way setup is ready for expansion. You can use it as the foundation for a 7-way installation kit, so your wiring investment keeps paying off as your towing needs grow.

Hi Tobin, the part # C56147 will not work for your 2014 Prius V, but the part # 118610 is a confirmed fit. I'll make sure you receive a return label for the one that won't fit.

It has been a year and Im still enjoying this product. When I was at Home Depot the other day getting Sheetrock a lady was asking about is as she had a blue Prius. I gave her product name and number which was conveniently on the hitch! I told her the ease of installing. Thanks again! Teresa

This was a LOT easier than I anticipated! Instructions are simple, the wiring harness is a real plug-n-play. Took me about 15-20 minutes. I never had a moment where I felt like I was in trouble with the installation. In fact, as I completed each step I found myself saying Thats it? Im really ready for the next step? Great product!

Thanks for your review, Scott! I'm glad to hear the wiring harness was a perfect fit and that you were able to get it installed in about 10 minutes. Running the plug through an existing grommet for a clean install is a great tip. Thanks for including the photos. What do you plan on using the wiring for?
