  • Reliable Signal Match: Built-in converter combines brake and turn signals for trailer lighting.

Features to know about

Installs Fast Without Cutting Wires: Plug-In T-Connector

Wiring a trailer doesn’t have to mean cutting and splicing wires. The Curt T-Connector with 4-flat trailer connector simply plugs into the vehicle’s existing tail light wiring. The connectors sit behind the interior trim, keeping everything hidden and clean. Most setups only call for basic hand tools like a screwdriver.

Keeps Trailer Lights Working Right: Solid Ground Connection

Intermittent or weak trailer lights often come down to a poor ground. This harness includes a white ground wire with a ring terminal that attaches to bare metal for a steady, full-power connection. A tight, corrosion-free ground ensures the brake, running, and turn lights all work without flicker or dimming.

Handles the Essentials for Safe Towing: 4-Flat Output

The 4-way flat plug delivers the standard lighting functions—brown for running lights, yellow for left turn and stop, green for right turn and stop, and white for ground. It gives small and mid-size trailers exactly what they need to stay visible and compliant on the road.

Built-In Converter Protects Vehicle Circuits: Reliable Signal Control

The harness includes a converter that properly combines separate vehicle light signals into trailer-compatible outputs. That protects your vehicle’s wiring from overloads and ensures each signal reaches the trailer just as it should. It’s a straightforward design that makes towing safer and more dependable every time you hook up.

One of the easiest things I've ever done on a car! Followed the video exactly and there was no way to mess it up. The only negative was that the VHB take included in the kit wasn't very sticky, but I wedged the controller in there so it wouldn't move. I will be picking up a similar kit for all future vechicles!

One year later the wiring is still working great! We just returned from a 700-mile trip with the trailer and had no issues with the lights.

by:
Good product overall. Installation instructions were a bit light on details - didn't mention that you needed to really pull hard to get the interior panels out. A better picture would have been enough.

One quality problem: one of the pins in the shunt connector was pushed out the rear of the connector - so the connection was intermittent at first. I had to go back in and find the problem - and push the pin back into the connector, which fixed the problem.

by:
Etrailer service/price excellent. However, the product doesn't work properly. Easy installation, lights didn't function the way they should. I purchased a universal assembly spliced it in ahead of the Curt unit and it worked perfectly. I cut the Curt out. It might work as a universal on another car. Loved the easy install it was worth the extra $25 to keep the connectors.

I've bought several products from eTrailer and have always been pleased with their service. A huge inventory, good prices and quick shipping make eTrailer my "go to" shop for my towing needs.

I bought this wiring harness for my Nissan Juke and it was quick and easy to install. I love the plug and play method of this harness. It's a lot cleaner (more professional looking) than the old method of splicing into wires to make the connections.

2013 Nissan Juke
I was pretty pleased to find out that there is a kit specific to my vehicle. I watched the video a couple of times before I even began the process. WATCH THE VIDEO. I went into the garage and began the process. I took all of the trim apart and removed the tire first just to see what I was going to need for tools and LIGHT. There's never as much light as you think. Once I got to that point I opened the package and made sure that I had all of the pieces. I followed the sequence on the video. WATCH THE VIDEO so that you don't plug the harness into the stereo system like I did. Fortunately it was just a matter of unplugging and plugging into the correct connections. After I put the wire where I wanted it I was going to use the double sided tape to anchor the control box. The double sided tape must have been old. There was no sticky left to it. I have a ton of duct tape ......... it's not going anywhere. If it were going to be visible I would have cared more. Any issues I have with the product are pretty much first word problems right now. A test light said that I'd done it right. as long as The plug-ins are good I should be OK. A Nissan Juke is a small car and this will be used only occasionally to tow a small trailer with three bicycles. I do like the fact that the plug is stored in the vehicle and will be out of the weather. Thanks Etrailer

I've been using this wiring harness on our 2014 Nissan Juke for over a year now, and it's worked flawlessly. Installation went smoothly, and it continues to perform perfectly. I had a question during the process, and the customer support team responded promptly and was extremely helpful. Highly recommend this product!

I have not installed the harness yet on my daughter-in-inlaws Juke, but so far dealing with etrailer.com has been fantastic. Product info, ordering and shipping was far above what I am used to, delivery was fast even with the holiday weekend. The quality of the harness is evident, very well made and engineered. I will be installing this week and will email an update. Thanks for the great service and a quality product. Michael

of taking time to carefully remove isde panels and base plate so as not to break the clips. I also purchased the tow hitch was equally as easy to mount. My total work time for both was about one and a quarter hours.

Thanks for checking in. I love the product still. It gets weekly usage from bike racks, to pulling a jet ski and trailers. Havent had any issues at all.

Good quality wiring harness, very easy plug in installation, instructional video was extremely helpful! All needed parts are included, even the grounding screw. I was very please with this wiring harness, and it works as it's supposed to! Great price as well.

2011 Nissan Juke
Very easy to install. With the very limited/vague instructions the not so mechanically inclined individual might be a little apprehensive to install, however not to difficult at all. Instructions should probably state that the panels that have to be removed are held in place with spring clips so that folks are not worried about breaking things.
by:
2014 Nissan Juke
Easy to use. Clear instructions. Trim on 2014 Juke is a pain, I just popped the side covers out enough to get to the area with the light connections. I had a threaded hole on the drivers quarter area. I used a spare metric bolt to attach the ground. I dont know what size it is, maybe a hair smaller than quarter inch with fine threads. Reccomend using that as a ground if you have it.
by:
Easy install, you can work it through the floor and repin the connector, or just leave it in the trunk and pull it out when needed.
by:
paneling. The dealer can do this for you in under 10 minutes. The bottom portion where the hatch back locks down has a plastic strip. This needs to be removed first.

Then driver's side and passenger side at the top of the read panels can be pry'd out enough to get your hand in there to attach the clips and sling the wire in whatever direction you wish it to exit.

The whole process should not take more than 15 minutes top.

Stopped working the second time I hooked up a trailer. The whole thing still looks brand new. Something inside the sealed box must have broken or come loose. Get another one somewhere else.

  • Troubleshooting Clearance Lights Staying On And Constant Power To Brown Wire On 2020 Ram 3500
    Hello Sergio. Constant power on the brown wire is an indication of a short. The brown wire or running light wire is likely shorted to a hot wire which is why the running lights are always on. I suggest you fully inspect your wiring and look for any damaged, cracked or frayed wires that could be causing a short. Then repair and replace as needed. The only other thing I could think of it you might have accidentally turned the head lights to on instead of auto. So please check and make sure...

  • How to Test a Trailer Wiring Harness Converter to See if it Needs to be Replaced
    It sounds like the box is at fault, but you can verify this by testing the input side of the box on the stoplight circuit wire (red) and then testing the output wires for the yellow and green wire of the 4-way. If there is voltage going into the converter box on the red wire when the brakes are applied but none are coming out then the box is bad and needs to be replaced. If there is no voltage going into the box then that wire isn't connecting to the correct circuit on your vehicle. You...

  • Constant Power on 4-Way After Installing Trailer Wiring Harness on a 2013 Nissan Juke
    It might be the tester. If the tester uses LED lights and it is a powered harness there can be some bleed off from the harness. This is normal and since LED lights require such little power draw they would light up a little. If you are using Curt wiring harness # C56124 on your 2013 Nissan Juke, it doesn't have a power wire. Green is right turn, yellow is left turn, brown is running lights, red is brake lights, and white is ground. Constant power usually indicates a short. Check the...

  • Troubleshooting Trailer Wiring Stop Turns Signals of 2007 Hyundai Santa Fe
    I think you are on the right track and that it's very likely it's the wiring connections for the trailer wiring or the converter box, but even easier than that it might be just corrosion on the pins of the connectors. Try cleaning the pins with sandpaper to see if that improves the contact and allows the pins to work properly. To test the converter box what you will want to do is test the wires going into the box of the converter box for voltage with a circuit tester like the # PTW2993...

  • Where Does the Curt Trailer Wiring Harness Install on a 2012 Nissan Juke
    You may not need any tools at all to install the Curt wiring harness # C56124 on your 2012 Nissan Juke except a screwdriver. The connection points for the T-connectors are located in the cargo area of the vehicle and you will just need to temporarily remove some trim panels. I have included a link to the instructions which also include some pictures that show the connections in detail.

    What you described sounds like an insufficient ground. But first you should check to make sure the 4-way is working properly with a circuit tester like part # 3808. Check out the video I attached to see how to do this. Find the main grounding point on the trailer by tracing the white wire from the trailer connector. This wire will usually ground to the trailer tongue. Make sure this connection is tight and that the connection is not corroded. Then check the ground connection for each of...

  • Troubleshooting Curt Trailer Wiring Harness # C56124 for 2012 Nissan Juke
    There are a couple things to check before replacing the unit, which may be the answer. First, check your vehicle fuses as listed in your owners manual. There are specific fuses for trailer use on your vehicle. The second thing to check is the ground wire on your wiring harness. If the ground is bad and isn't getting the bare metal to metal contact it could have worked and then suddenly stopped working as you stated. Use a circuit tester like # PTW2993 to check functions.

  • Trailer Brake Lights Do Not Work But Turn and Running Lights Do On 2013 Nissan Juke
    The issue you are having with the Curt T-Connector Vehicle Wiring Harness part # C56124 is most likely attributed to a poor ground. Therefore, I recommend that you remove the ring terminal for the ground, sand down the surface, and then reattach. There have been others with this same issue that was then resolved when the wiring harness was re-grounded. If you still continue to have issues after the ground has been checked please just let me know. I would also be sure to check the pins inside...
