CURT Custom Fit Vehicle Wiring - C56011

  • Trailer Hitch Wiring
  • 4 Flat
  • Converter
  • CURT

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
  • 1-Year limited 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.

This harness did not fit the vehicle (2018 Fiat 124 Spider) it was recomended for. The part was recomended by etrailer.com but did not fit. See picture of packaging, It should have been pretty obviouse this was not going to fit. To return it they wanted to charge me almost $xx. Caution ordering from this web site, if they recomend it and it doesn't fit you are going to pay shipping to return it.

I am sorry to hear that this harness did not fit your 124 Spider. I do see that we do not carry anything on our site that will work on your vehicle. I am not sure how this harness even came into your search, but I will definitely make sure that this mistake will not happen again. As for finding a harness that will work, I would highly recommend contacting Fiat to see if they have a harness that they would recommend.

Very easy install, just make sure the ground wire has proper contact with the chassis or you will have issues with trailer lights doing some crazy things.

Great product and great service, easy plug and play install



by:
2015 Mazda CX-5

I am quite happy with this wiring kit! It truly is plug and play!!
After watching the video, the install was quick and easy.
I only deviated from the install video, where it concerns the ground wire.
It says to use a drill and make a 3/32 hole and use the self tapping screw, if you can not find an existing place to mount the ground wire.
On the CX-5 there is a perfectly placed nut that can be used, and you dont even need any extra tools above what the kit calls for.
When you pull off the plugs for the drivers side tail lights, you will also see 3 10mm nuts that hold the tail light in place.
Just remove the one below the brake light, and slip the ground wire over it and replace the nut.

I havent had to pull any more trailers, but I have no doubt it will work just fine, the next time I need to unroll it from the spare tire well!

By far the easiest install i have done in a long time.

Still working perfectly use it a lot because I use my little Mazda to tow my small boat to go fishing.



by:

Seems to be high quality and perfect fit. I have hauled a few things with it, no problem. My advice is to just fully remove the muffler instead of dropping it. If you are installing it in your driveway like I did. It was very difficult to get leverage to squeeze it into place, but once I pulled the muffler, easy.

Bought for 2015 Honda Accord. The plugs did not match the vehicle. Confirmed that it was corrrect and was told Honda screwed up and to splice it in.

I am sorry that it needed to be spliced. Does your Honda Accord have LED tail lights? If it has LED tail lights then you would need part # C56173.

2015 Mazda CX-5

Super easy to install. Still need to test it with a trailer though.



by:

Fit my car application and fast shipping. Thanks!



by:

Wiring was easy, aside from some inevitable tight quarters gaining access to the rear of the taillights to connect everything.

Works great! Detailed instructions.

Excellent service and response time on sending the part was supper.

2015 Mazda CX-5

The hitch was great and went on without a problem. Wiring also worked great. Done! I bought from you because of your videos and they made installation so much easier. I am a do it yourselfer but at 73 was thankful for all you information and help via the videos. Would recommend your site to anyone in need of a hitch.

2008 Honda Civic

Very easy to install, and good plug len gth.



by:

Very simple installation that connects to the existing tail light connectors without any extra splicing of wires



by:

Great product, does what it says. Instructions were very generic and poorly written, and omitted a critical step - connecting the second in-line plug on the driver side for the running lights. Apart from that the install was very easy. The supplied adhesive mounting pad for the converter would not stick to the trunk interior paint, so I used heavy-duty hook and loop instead.



by:
2015 Mazda CX-5

Item was plug and play as advertised. Paper instructions included are marginal. Site provided video was very helpful.

This is my second installation using etrailer; they've been good to deal with each time.



by:
2015 Honda Accord

I installed this on my 2015 Honda Accord for the purpose of pulling my small aluminum fishing boat and trailer. Works great!



by:

Too easy to install!! I wish I could have found kits like this years ago! .. Kits like this should be the standard!



by:
2014 Honda Accord

Very easy to install and just enough wiring for an Accord that there are no wires dangling in any locations.

Easy to install, worked as expected

I am pleased with your service and the product. Ease of installation is the best thing.

easy install and works great.

2014 Mazda CX-5

Shipping was prompt and without issues. The install
On my 2014 Mazda cx5 was easy and stright forward. I watched the install video on the product page for CX5, and just
Followed the steps in video. Took 10min to remove interior panels, ect, and 10 min to make all plug and play connections, no issues.
Then 10min to put panels back in place. Tested the flat connector
As described in video. Works perfectly. This is after I went to Uhaul and they spent almost 2 hours under my CX5 baffled and unable to install a traditional trailer wire kit. I left with hitch only and installed this plug and play kit, completely satisfied.

Thanks so much.

My wife and I installed a 2" Curt trailer hitch (and wiring) on our 2015 Mazda CX-5. Total installation time was about 2 hours. We didn't have any problems with the instillation of the hitch or wiring. Etrailer has a video link available, which should be viewed before you begin your installation. However, there wasn't any audio with this.
The hitch is solid and appears to be well built. Occasionally, we pull a small aluminum trailer loaded with kayaks, or other light items.
We have ordered from Etrailer before and feel they are a good company to do business with.

Weve had our Curt hitch for over a year now and it still looks like new. Were very satisfied and recommend Curt and Etrailer.

  • Trailer Works with One vehicle But Not Another
    This sounds like a ground issue. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached to clean and corrosion free bare...

The drawbar has a tongue weight up to 200 pounds which will work perfect with your 550 pound boat trailer. The drawbar has a corrosion-resistant, black gloss powder coating. You also need either The 1-7/8 inch ball # C40001 or The 2 inch ball # C40018 for the draw bar....

  • Trailer Wiring Options for a 2015 Honda Civic
    If your 2015 Honda Civic is a sedan and not an Si or hybrid then for a trailer wiring harness I recommend Tow Ready harness # 118420. I have included a link to a video showing an example installation for you. For a coupe use # C56051. For a sedan Si use # C56011. For a sedan hybrid use # C59236.

  • Trailer Wiring Harness for a 2016 Honda Fit
    Trailer wiring harness # C56011 does NOT fit the 2016 Honda Fit. The 2016 models require a hardwire system. You can use the ZCI harness # 119250KIT. This harness requires a power wire to the battery and has connectors that clamp around the vehicle tail light wires, so you don't have to do any splicing.

  • Recommended Hitch Receiver for 2015 Honda Civic Towing Jet Ski Trailer
    Yes, the Curt # C11391 would work, but there are some other factors that really make the EcoHitch a much better option. First, considering you've got a 2015 Honda Civic, ground clearance is going to be an issue since both the cross tube and receiver will sit below the bumper, making it much more prone to bottoming out. Because the EcoHitch # 306-X7235 has a concealed cross tube that mounts behind the bumper, it's going to give you some extra ground clearance that's going to be extremely...

  • Parts Needed For Towing a U-Haul Trailer With a 2013 Honda Accord Sedan
    Curt recommends using the Ball Mount # C45521 in the rise position with their Receiver # C11681 on your 2013 Honda Accord. You will need a Hitch Pin and Clip # F-4 to hold the ball mount in the receiver and a 2" Ball # C40018 to connect the U-Haul trailer. You will also need a 4-way Curt Harness # C56011. The 4-way will send power to the trailer tail lights from your Accord.

  • Recommended Tow Bar Wiring For 2013 Honda Fit Being Flat-Towed
    The Curt T-Connector Vehicle Wiring Harness, part # C56011 is designed to work with your Honda Fit to tow a trailer behind the vehicle. This harness is not designed for operating the lights on your Fit while it is being towed. For that you would need tow bar wiring. When you flat-tow your Honda, you will need kit like part # 154-792-118158. This is a diode kit and includes the converter needed for your Honda with separate wire(meaning the brake light bulb is separate from the turn signal)....

  • Recommended Trailer Wiring Harness For 2016 Honda Civic Sedan
    We do have a wiring kit that will work with your 2016 Civic but they require hardwiring the harness on your vehicle. Curt T-Connector Vehicle Wiring Harness, part # C56011 is not a confirmed fit for your 2016 Civic. The harness I recommend for your Civic is the Tekonsha # 118686.

  • 7-Way Trailer Wiring Recommendation for 2015 Mazda CX-5
    We have a way you can install a 7-way on your 2015 Mazda CX-5 but not all vehicles have custom fit 7-ways made for them so you'd have to start with the more common 4-way like the part # C56011 which is custom fit for your vehicle. From there you'd need to convert it to a 7-way like what your trailer needs. If the trailer does not have brakes all you need is the # 37185 which plugs right into the 4-way and you'd be set. If the trailer does have brakes you'd instead need the # ETBC7 which...

  • Trailer Hitch, Wiring Harness and Ball Mount for 2015 Honda Civic LX Sedan
    I checked with Curt and the correct wiring harness for a 2015 Honda Civc LX Sedan is Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56011. For a hitch you will need # C11391 and Curt recommends the use of Ball Mount # C45521. This will require 2" Hitch Ball # A-82 or 1-7/8" Hitch Ball # A-80 as well as Pin and Clip # F-4.

  • Hitch and Towing Setup Recommendation for a 2015 Honda Accord Coupe
    The Curt item # C11496 that you referenced does not include the recommended ball mount, part # 3593. With a Class I hitch like this you can only use the recommended ball mount for the hitch. For a hitch ball you would want the part # 19256 for a 1-7/8 inch ball or part # 19258 for a 2 inch hitch ball. If you have a coupe with LED taillights you would want the part # C56173 for trailer wiring or part # C56011 for with incandescent bulbs.

  • Trailer Wiring Harness Recommendation for 2013 Mazda CX-5
    Either trailer wiring harness that you referenced would work great for you. Both the Tow Ready harness part # 118563 and the Curt # C56011 would work on your 2013 Mazda CX-5 that has incandescent lights and your trailer that has LEDs. We tend to have better luck with the Tow Ready harnesses so I would go with the # 118563. I attached an install video for you to check out as well.

  • Trailer Hitch Recommendation for a 2014 Honda Accord Coupe
    The Curt hitch part # C11681 is the most popular hitch we offer for your 2014 Honda Accord and only requires you trim the heat shield as far as permanent modifications go. There wouldn't be any drilling or rear bumper trimming. The exhaust does have to be temporarily lowered but that is pretty standard for trailer hitch installs.

  • Comparing Tow Ready # 118563 and Curt # C56011 Wiring Harnesses for 2016 Mazda CX-5
    The Tow Ready T-One Vehicle Wiring Harness # 118563 is a correct fit for your 2016 Mazda CX-5. The other harness offered, Curt # C56011, does not fit your 2016 CX-5 due to a change in connectors from the 2015 model year. Note that there are two major advantages to using the Tow Ready harness. First, this harness will isolate and protect your new vehicle's wiring from any potential shorts or overloads from the trailer because it draws power for the trailer directly from the battery, not...

  • T-Connector Vehicle Wiring Harness For 2016 Mazda CX-5 With LED Lights
    The correct Curt wiring harness for your 2016 Mazda CX-5 is part # C56310. The connectors changed between 2015 and 2016 for the CX-5 and the # C56011 will not work with your 2016. Per my Curt contact, the # C56310 will work fine with the LED lights on your CX-5. You just need to access the wiring connection points in the rear cargo area and then run a hot lead to the car battery. This harness includes a tail light converter that keeps the electrical system on your vehicle from being overloaded.

    Curt trailer wiring harness # C56011 will work great with the LED tail lights in trailer light kit # TLL9RK. The Curt trailer wiring harnesses that require power from the vehicle battery to power the trailer lights tend to dimly light LED trailer tail lights even with the vehicle turned off. However, harness # C56011, is not a powered converter so that problem should not happen at all. I have linked some videos on both the light kit and the trailer wiring harness for your reference.

From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7.
