Features to know about

Installs Fast Without Battery Wiring: Plug-In Harness

This Curt T-Connector makes wiring simple since it doesn’t need a direct line to the vehicle’s battery. Everything hooks up behind the tail lights using factory plugs, so there’s no extra power wire to run. It’s a clean setup that gets your trailer lights working in less time.

Simplifies DIY Trailer Wiring: Plug-and-Play Connection

Instead of cutting or splicing wires, this harness plugs right into your vehicle’s existing tail light connectors. That means no tracking down wire functions and no guesswork. Just snap the connectors in place and you’ve got a solid 4-flat output ready for your trailer lights.

Covers the Basics for Small Trailers: 4-Flat Connector Output

The included 4-flat plug provides running lights, turn signals, and brake lights for utility trailers, small campers, and boat trailers. It’s the standard connection that gets the essentials powered up for safe towing.

Keeps Install Hidden and Protected: Behind-Panel Fit

The harness tucks neatly behind existing trim with a converter box that stays out of sight. The design keeps everything protected from road grime while giving a clean, factory-style finish once installed.

Video Transcript for Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C56206 Review

Today we're going to be taking a look at part number C56206. This is the currency connector vehicle wiring harness with a four pole flat trailer connector. This product is going to fit certain years of the Nissan Versa Note. It's going to provide your four way flat connector at the back of your vehicle to power your trailer's signal lights. It is compatible with five pole, six pole and seven pole adapters. Adapters are sold separately. It's going to come with your dust cap for the four way flat connector, that way you can cover up those connection points when the plug is not being used. The black box right here is going to be your included tail light converter. This is going to ensure your vehicle's wiring matches out of your trailer's.

This is going to be constructed using surface mount technology. It's really going to help maximize the trailer light yield and intensity while producing minimal heat. It's also going to ensure superior operation, even in rough road conditions. Now, one of the main benefits of a system like this is that it's designed to connect quickly and easily. All you have to do is look at the connection points in your rear cargo area. It comes with detailed instructions to indicate exactly where those are. The instructions are also going to help walk you through the installation process step-by-step.

They're going to feature some really nice, detailed pictures. That way it really does assist with the installation. Pictures are always a great thing to go by and it's got all the steps listed out as well, so those are going to come in handy. Identify where those connection points are, plug in your connectors. The connector with the yellow wire is going to go on the driver's side. Connector with the green wire is going to the passenger's side.

Yellow, driver's side. Green, passenger's side. So plug in the connectors and then you'll need to make a ground connection. That's going to be the white wire with the ring terminal attached to it. You want to get that grounded to a nice, clean metal surface using the included grounding screw. Again, that's the white wire with the ring terminal attached to it.

The screw is included. Then you can mount the converter box with the double sided adhesive tape provided with the kit. Then you'll need to secure any excess or slack in the wire with your included zip ties. Once your installation is complete, the four way connector is going to be stowed in an out-of-the-way location within your cargo area. Now, when it comes to the amperage for the stop end trailer lights, we're looking at 3 amps per circuit and for the tail lights we're looking at 5 amps per circuit. It's also recommended that you use a small amount of grease on all your electrical connections. Terminal grease or dielectric grease, like the plugs on the vehicle and on the four pole connector itself. That's going to help prevent corrosion. If you need some of that but don't have some, you can find that right here at eTrailer.com. It is sold separately. That's going to do it for today's look at part number C56206.

Great harness very easy to install. Works great. Dose come with plenty of wire to make sure you don't have to stretch it to hook up trailer. It did take a little bit longer on shipping but wasn't etrailer fault. Mail is slower with all going on. I did call and talk about anything with etrailer very nice people and helpful

after looking at installation , I decided it would be in my best interest to take it to my mechanic , he stated I could have installed it but it did require more work than it first appeared . I have not used it yet so I can't comment on that aspect . Being for light weight use, I do not believe there will be a problem .

  • Comparing Curt and Tow Ready Trailer Wiring Harnesses for a 2014 Nissan Versa Note SL
    Like you mentioned, the Curt trailer wiring harness # C56206 for the 2014 Nissan Versa Note does not require a direct connection to the vehicle battery whereas Tow Ready harness # 118582 does. At the back of the vehicle the installation of the harnesses will be the same. The only difference is that power wire on the Tow Ready harness. That power wire is what will power the trailer lights. With the Curt harness the trailer lights will be drawing on the vehicle tail light wiring. Modern...
