Features to know about

Installs Without Cutting or Splicing: Plug-In T-Connector

Wiring for towing doesn’t have to be complicated. This Curt T-Connector plugs directly into your vehicle’s existing wiring, giving you a 4-pole flat trailer connector without cutting or splicing. The plug-in design keeps the factory wiring intact and makes it easy to get trailer lights working fast.

Delivers a Clean, Hidden Setup: Behind-the-Panel Mounting

The harness tucks neatly out of sight for a clean look once installed. Its hidden routing keeps the wiring protected from the elements and prevents clutter around the hitch area. You end up with a factory-style finish that looks tidy and professional.

Reliable Power for Trailer Lights: Powered Converter Module

Built with a powered converter, this harness draws a direct power feed from the battery instead of overloading the vehicle’s tail light circuits. That means steady, consistent output for your trailer’s running, brake, and turn lights—even when using multiple or LED lights.

Ready to Tow with Standard 4-Flat Connector: Simple Hookup Every Time

The 4-flat connector gives you all the basics for towing—running lights, turn signals, and brake lights in one plug. It’s the standard connection used on most small and mid-size trailers, so you can hook up quickly and hit the road with confidence.

Video Transcript for Review of the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector-C83VV

Hi everybody, Andy here with etrailer.com. Let's take a look at this Curt T-connector vehicle wiring harness with four-pole flat trailer connector. Now this is a custom fit harness and it is designed specifically to fit your 2020 and newer Nissan Sentra. On custom fit parts such as this wiring harness, I do recommend taking advantage of our vehicle fit guide here at etrailer.com. Input the year, make, and model of your vehicle and our fit guide will confirm if this will work for you or if we have something comparable that will work for you. Now this harness is going to give you a four-pole flat trailer connector at the back of your Sentra to power your trailer signal lights.

This is going to be compatible with five-pole, six-pole, and seven-pole adapters, and those adapters are sold separately. And included is this dust cap for the four-pole flat connector. This dust cap is going to cover up those connection points when this plug is not being used. Now looking at the back portion of this harness, we have a powered taillight converter. This is going to ensure that your vehicle's wiring matches that of your trailer.

And this is going to connect directly to your vehicle's battery to avoid overloading your vehicle's electrical system, reducing strain on your vehicle's wiring system. And Curt builds each converter using surface mount technology for consistent, reliable performance. It's going to maximize your trailer light yield and intensity while producing minimal heat, ensuring superior operation in rough road conditions. Now this harness is designed to connect quickly and easily. The connections with the yellow wires are gonna go on your driver side and the connections with the green wires are gonna go to the passenger side of your Sentra.

And you will need to locate your vehicle's wiring harness, which should be located behind the driver side and passenger side taillights. To locate that harness, you will have to pull back some of the trunk liner. And once you locate the connectors, then you're gonna separate the connectors. And you wanna be careful not to break the locking tabs. And then you're going to insert these T-connector ends between the vehicle wiring connectors and then lock them into place.

These T-connectors are custom fitted for your Sentra, so they will match up perfectly with the connection points on your Sentra and they snap and locked together for a tight secure fit. Once you have these plugged in, you will need to make a good ground connection. The ground wire is this white wire. And as you can see, it does have a ring terminal attached to it. And it does come with a self-tapping screw. And so you can get this grounded to a suitable location such as your Sentra's frame or crossmember. You just wanna make sure that the surface that you mount this on is clean and rust free. Next, you will need to mount the converter box to a safe out-of-the-way location. You can do this with another mounting screw as you can see here that you might have on hand or with this included double-sided adhesive tape or maybe even with one of the many included cable ties that's provided with this kit. Next, you will need to run the hot lead to your vehicle battery. And that hot lead is the short black wire that's coming out of the converter box. This short black wire is going to get connected to one of the ends of this included bundle of black wire using one of the included butt connectors. And then the other end of this bundle is going to get routed to your vehicle's battery. Once you have this routed to the battery, you're going to take the fuse holder that you see right here and connect one of the wires with the second butt connector to the routed wire. And then the other half of this fuse holder is going to get this ring terminal attached to it, and then that's gonna connect to the positive post of your vehicle's battery. This does come with a 10 amp fuse that's gonna go into this holder. And then it has a cap here to keep that fuse safe and protected. So you can secure any of the excess wiring that you might have with the included cable ties that we have here. And once this, once the installation is complete, this four-way connector will be stowed in an out-of-the-way location within your trunk. The maximum amperage for the stop turn lights is three amps per circuit, and for the tail lights at six amps per circuit. Instructions are included to walk you in a little more detail through that installation process. And then it is recommended that you use a small amount of dielectric grease on all of your electrical connections, like your plugs on the vehicle and the four-pole flat connector itself. So what this grease does is that, it's designed to help prevent electrical failures caused by corrosion and moisture. So if you would like to check that out on your screen, I am including our item number for a tube of dielectric grease. You can take that item number and put it in the search field of our website. That will take you to that grease and you can add that to your order if you so desire. Well that's going to wrap up our look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
