Curt Custom Fit Vehicle Wiring - C56124

  • Custom Fit
  • Trailer Hitch Wiring
  • Curt
  • 4 Flat
  • Converter

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required. Converter is made using SMT to ensure superior performance.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection points in rear cargo area
    • Plug in T-connector
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
  • Constructed using surface-mount technology (SMT) for consistent, reliable performance
    • Maximizes trailer light yield and intensity while producing minimal heat
    • Ensures superior operation in rough road conditions
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 3 amps per circuit
    • Tail lights: 6 amps per circuit
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side interior trim panels in your rear cargo area.


Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.


Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.


Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

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. 680799

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. 575440

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. 522396

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 268489

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. 219910

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. 97865

You need a tool specific to removing plastic 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. 59844

Install was very easy, it is just a matter 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. 34058

Ask the Experts about this Curt Custom Fit Vehicle Wiring

  • 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....

  • 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...

  • 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...

  • 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...

  • Trailer Lights Work Sporadically With Curt Harness # C56124 Installed on 2013 Nissan Juke
    Since you have rewired your trailer and have tested it successfully with another vehicle, it is most likely that the trailer lighting issue you are having is related to the harness installation in your Juke. Please note, just for your safety, that the 2013 Juke owners manual indicates on page 9-15 that this vehicle should not be used to tow any trailer. First check that the white ground wire with the ring terminal is very tightly attached to a clean bare metal surface behind the driver-side...

  • Troubleshooting Trailer wiring on a 2011 Nissan Juke Where StopLights Dont Work but Blinkers Do
    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...

  • 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.

  • 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.
