  • 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

    • Plug in T-connector
  • Comes with dust cap for 4-way flat connector


  • Amperage allowance:

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness.

Once installation is complete, the 4-way connector will be stowed within the jack storage compartment of 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.

As a Chrysler dealer, this harness fits perfect every time.

2003 Dodge Grand Caravan

Ordered a Curt trailer hitch receiver to mount on a 2003 Dodge Caravan to pull an old Scamp trailer. Came promptly, installed easily and works well.

2003 Chrysler Voyager

I have purchased many different items from e-trailer.

Every order I bought shipped quickly and came without damage.

Instructions to do wiring or put on the hitch are very clear and only a phone call away if issues occur .

Never had a problem with e-trailer and would highly recommend them to anyone wanting to save money on a self install of trailering products.

Bought a electric brake controller and it was matched to my tow vehicle with quick plug in hook up no cutting and splicing or using a meter to figure out wiring same as putting in the wiring plug no fuss hook up.

When calling and speaking to a sales associate they are very polite and precise to the product and the vehicle application matches.

2001 Chrysler Town and Country

Once again everything I ordered for this hitch were excellent products. Directions great, videos, all parts in the boxes down to wire ties and dust caps in true English not poorly interpreted gibberish. Glad to do business with your quality organization, please don't dilute the quality to compete with the bargain bin places. It is one thing to buy a cheep wrench for the kids to use but I install trailer hitches to keep trailers attached to vehicles.


The easiest way to connect trailer lights. Drivers side tail light and harness fishing through to the bumper and hitch. Simple no drama or special splicing. Plugged right in.


This product is not compatible with my SUV, I tried to return it but was past the time I was allowed to do so. This product still sits in the original packaging in my garage. Sorry that I have nothing good to report.

This wiring harness isnt listed as a fit for your twenty eighteen Audi QFive. We do have wiring kits like part # 119147KIT. But when choosing vehicle specific products like wiring, it is important to always go through our fitgu8ide and note the Tech Tips to ensure compatible parts are chosen.


The install was great and went smooth no problem. The youtube videos on how to install the trailer light adapters were great. Took me about 20 min. to complete the job. The only draw back was that I elected to go with the "route-the-wire-through- the-tirejack-box" route. It was fine, except that when I rented a U Haul trailer the wire wasn't long enough and it disconnected from the trailer on sharp turns. So I rerouted the other way they demonstrated and it worked fine. My advice is go through the bumper, not the tire jack box. The rerouting only took me another 20 min.


Quality wiring harness, easy to install, clear instructions, worth its price. Other brands have failed on me, I highly recommend Curt products. E Trailer ships fast and I use them often. Very pleased, you will be too!


I had a great experience with trailer and there personnel were very helpful. I purchased the trailer wireing,receiver and trailer tires. Awesome company!!!

Chrysler Town and Country

It was perfect for our Chrysler Town and Country and easy to install. We were able to tow a trailer with reliable lights.


First , the online order was easy and fast . I received an email within a few hours that the harness has been shipped. I received the wiring harness within the timeframe promised. Installation was straight forward and works beautifully. I am very happy with my etrailer experience.


This kit is very easy to install. Newer vehicles are impossible to wire from scratch, this unit plugs in and solves all the problems. No splicing or soldering. Lots of miles on it and no problems at all!


Tow package integrated signaling system installed easily and has worked without fail!


A reputable parts store wanted to charge me $235 to install this, but the do-it-yourself video made installation a breeze! Took me a little over 20 minutes! Highly recommend etrailer!!


Fast, friendly service. Very easy to install. I had it on and everything put back together in about 15 minutes. I used an old tape measure to fish the wires through. Worked great. Thank you, Amanda

2003 Dodge Grand Caravan

Although the directions are a bit vague and the picture's numbers and letters don't match/jive, I figured it all out and the installation was successful.

1998 Dodge Durango

everything was on time and quality looks very good, I am about to install. So far you guys did a top job and I am impressed. Oh and the quality of the LED bar for the price I paid, great job. Good company thank you


I haven’t put it on the vehicle yet. But soon…..

2001 Chrysler Town and Country

fast delivery of quality products. ordered sunday afternoon, used my paypal account ( always gets quick attention), parts on my porch on wednesday noon. the Curt T connector wiring kit made the wiring hookup even easier than the ordering, and was finished in no time.


Product has been performing flawlessly. Easy to install.


Perfect fit I was able to install it easily without any problems

2003 Chrysler Town and Country

Fast, reasonable shipping. Easy to install "plug & play". Haven't had the opportunity to use yet and won't for another 3 weeks but I don't forsee any problems.

2003 Chrysler Town and Country

Only used it 1 time


Product as described, easy to install, quick delivery. Thanks


Quick service and fast, free delivery.

  • Trailer Wiring Harness for a 2010 Dodge Nitro
    For your 2010 Dodge Nitro you will need a different wiring harness. I recommend # 118554 to add a 4-Way flat connector to the rear of the vehicle. The one that you referenced was designed for 2001 to 2003 Chrysler and Dodge mini vans but not your Nitro. I have linked a video showing an example installation of 118554 for you. I have also included a link to a help article I wrote with tips on routing the power wire.

  • Plug in Wiring Harness for a 2020 Jeep Grand Cherokee
    Yes, we do have a wiring harness that will attach to your 2020 Jeep Grand Cherokee without having to splice wires. It is the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector item # 118727. This custom-fit T-One connector plugs into your Jeep's wiring harness behind the rear tail lights. It will provide you with a 4-flat connector. I have linked an installation video.

  • Federal Requirement for Trailer Lighting and Best Options for Adding Lights to a Utility Trailer
    There are minimum lighting requirements for trailers that vary based on trailer size and weight, but to our knowledge there are no maximum limits for trailer lights, provided that all the mandatory lighting is installed. We've recapped the federal requirements in the linked article which will give you specifics. I am sure there is a law enforcement officer out there somewhere that might pull over a motorist for having what he/she considers "excessive" trailer lighting, lighting that is...

  • Trailer Wiring Harness for 2012 Chrysler Town & Country
    We do have trailer wiring harnesses for your 2012 Chrysler Town & Country but this particular wiring harness, # C55376, is meant for Chrysler Town & Country 2003 or older. The trailer wiring harness that is designed for your vehicle is the Curt T-Connector Wiring Harness # C56331 and is confirmed to fit your 2012 Chrysler Town & Country. Running a power wire to your battery is going to be required in order to protect your vehicle's lights and components from being overloaded by a short...

  • Could Curt Hitch part # C13362 for 2003 Chrysler Town and Country Tow Motorcycle Trailer
    Sounds like you are asking if the Curt hitch part # C13362 has the capacity to tow a motorcycle trailer. Since it has a capacity of 4,000 lb and motorcycle trailers are typically much lighter weight than that I'd say this would easily work for that. You would also need trailer wiring for that with part # C55376 that fits your 2003 Chrysler Town and Country as well.

  • Trailer Wiring Harness for a 2017 Dodge Grand Caravan
    For your 2017 Dodge Grand Caravan you can use Curt T-Connector Vehicle Wiring Harness # C56331. This and all of the wiring harnesses for your van do require a direct connection to the vehicle battery. This harness will work with LED trailer lights. I have linked a video showing an example installation of this harness for you.

  • Troubleshooting Curt T-Connector Vehicle Wiring Harness C56331 Voltage Drop When Connected To 4-Way
    I think you may have a ground issue with the Curt T-Connector Vehicle Wiring Harness # C56331 on your 2013 Chrysler Town and Country. To verify if this is truly the issue you can disconnect the ground wire and run a jumper wire directly to the battery. On these Town and Country minivans they are know to have ground issues for body mounted grounds and that may be what caused your Tekonsha to fail. Please let me know if this resolves your issue.

  • Will Vehicle Wiring Harness For 2008 Dodge Nitro Work With Incandescent and LED Lights?
    The vehicle wiring harnesses confirmed to fit your 2008 Dodge Nitro, the Curt # C56334 and Tekonsha # 118554, will both work with incandescent or LED lights and neither will damage the module. Between the two I recommend the Tekonsha # 118554 because in our experience we have heard great seen them last longer and be more reliable that other manufacturer's, and as such they have become a favorite of our installers. I included a video of the # 118554 being installed for you to take a look at.

  • Vehicle Wiring Harness For Trailer Lighting On a 2001 Harley Davidson Road King
    I recommend using the Tekonsha ZCI Circuit Protected Vehicle Wiring Harness # 119250KIT for your 2001 Harley Davidson Road King as we will not have a custom fit wiring kit. This kit features wiring sensors that will detect the power running through the taillight wires. This protects you from having to splice into the wiring or risk overloading the wiring that Harley installed. A Mounting Bracket # 18144 can be used to secure the 4-way plug on the back of your Road King.

  • Trailer Wiring Harness for 2021 Toyota Camry LE Hybrid with Incandescent Taillights
    I spoke with my contact at Curt, and from what I understand they're working directly with you on this. They're wondering if your Camry might have been manufactured in Canada, the Curt 56417 which we sell as part # C34FR won't work correctly on Canadian manufactured vehicles. According to Tekonsha, the # 118763 is a fit for all models of the 2021 Camry. The Hopkins wiring harnesses you specified are for vehicles being flat towed behind a motorhome, not for towing a trailer so they wouldn't...

  • How to Easily Determine if Converter of Trailer Wiring Harness is Bad
    To troubleshoot whether or not a trailer wiring harness converter box is functional you just need a circuit tester like part # PTW2993 to test for voltage on all of the circuits on the input side of the box and then if they are all there then test the output side. If the box is bad you'll find voltage on the input side but none on the output side. At this point it would be best to replace the entire setup with something like the Curt # C55376.

  • Hitch Recommendation for a 2002 Chrysler Town and Country
    I have a hitch solution I can recommend for your 2002 Chrysler Town and Country, but the Curt hitch part # C14355 that you referenced would work as was designed to fit newer Ford trucks. Instead you would want the Curt hitch part # C13362 as it has been confirmed as a fit for your vehicle. I attached a review video for you to check out as well.

  • 7 Way Plug For Wiring 3rd Brake Light On A Leer Camper Shell
    The best product we have for wiring third brake lights on a Leer camper shell is the 3rd Brake Light Logic Module # PP20-702. This will filter out any unwanted signal from the tail lights and allow the 3rd brake light to activate only when the brakes are applied. You can combine this with an in bed harness like the # C56000. This way you can connect to the 7 way plug in the bed, and still have your 7 way on the back if you need to use it for towing.

  • Trailer Hitch and Wiring for a 2015 Chrysler Town and Country
    The most popular trailer hitch for your 2015 Chrysler Town and Country, and what I recommend, is Draw-Tite trailer hitch # 75579. This is a Class III hitch with a 2 inch receiver so it is a versatile option compatible with many accessories. I have included a link to a video showing an example of this hitch for you. If you plan on doing some towing I recommend etrailer ball mount kit # EBMK4EL. It comes with a ball mount with a 2-3/4 inch rise or 4 inch drop, interchangeable ball set, hitch...

  • Which Trailer Wiring Harness is Better for a 2013 Toyota Sienna, Tekonsha or Curt
    I do have the correct trailer wiring harness for your vehicle but neither the Curt T-Connector Vehicle Wiring Harness part # C55376 or the Tekonsha T-One Vehicle Wiring Harness part # 118648 are a confirmed fit for a 2013 Toyota Sienna. Instead you will want to use either part # 118498 for Tekonsha or part # C56106 for Curt. I recommend going with the Tekonsha wiring harness as over the years we have heard much better things about the reliability and longevity of their wiring products compared...

  • Brake Controller, Wiring and Hitch Recommendation for a 2002 Dodge Grand Caravan
    The first thing wiring related you need for the towing setup of your 2002 Dodge Grand Caravan is a 4-way. This is the trailer wiring that controls the turn signal functions of your trailer. For that you would want the Curt Wiring Harness part # C55376. This installs easily by plugging in line with your vehicle taillights. Next you need to convert the 4-way to a 7-way so that it will match your trailer's connector and so you can install and use a brake controller. For that you need the...
