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 tail lights. You will have to remove the tail light assemblies to access this harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


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.


Powered Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


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.

Video Transcript for Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C56331 Review

Speaker 1: Today we're going to look at the Curt T-Connector Vehicle Wiring Harness with the Four-Way Flat Trailer Connector. Now, this is a custom fit part. It is designed to fit the 2011 and newer Chrysler Town and Country and Dodge Grand Caravans. Now, on a custom fit part, I always like to recommend for you to go to our website, use our fit guide, put in your year and model vehicle, and it'll show you if this will work for your application. Now, this harness will provide this four-way flat trailer connector at the back of your vehicle, to power your trailer's signal lights. This is compatible with five-pole, six-pole, and seven-pole adapters that we do sell separately on our website.This whole harness does connect very quickly and easily.

Basically, you just locate your connection points, which are behind the tail lights in the rear of your vehicle, plug in these T-connectors, one on each side. One on the driver's side, one on the passenger side. Ground your white wire, and then this black wire's the power wire, that you'll run to your vehicle's battery at the front of your car. Now this harness does include this powered tail light converter, which is this black box here. This connects directly to your battery, so this avoids overloading your vehicle's electrical system.This converter is constructed using SMT technology, which is Surface Mount Technology.

Gives you consistent, reliable performance. This will maximize your trailer light yield and intensity, while producing minimal heat, and it even ensures superior operation in rough road conditions. On the four-way, if you notice, it does come with this nice dust cap for it. Basically, when you're not plugged into your trailer, you can just put that over the terminals, keeps them from getting damaged from the elements. This whole harness is made in the USA.

Comes with everything shown here on the table. Now the specs on this, the maximum amperage on the stop and turn light circuits is three amps per circuit. On the tail lights circuit, it's six amps.Comes with a nice set of detailed instructions that'll describe how to install it, and it even gives you pictures of where your connections are. But just briefly, how this goes into your vehicle. What you want to do is, again, go to the rear of your vehicle.

Gain access to the back of the tail lights, and you want to start on the driver's side. You'll take this T-connector here, it has the yellow wire in it. That's for the driver's side. You unplug the harness behind the tail lights, plug this into that. Then you'll take the other T-connector that has this extra length of green wire. That's for the passenger side. You run this all the way over to the passenger side, you'll do the same thing. Plug this in behind the tail lights.Once those are all plugged in, then you want to take this converter box, and you do want to attach this to a good flat surface so it doesn't bounce around, so they do include this nice piece of double-faced tape that you can attach it down with. Once that's all done, you have two wires remaining here. Now, your four-way that's attached to this bonded wire, this you'll just run out the back towards where the trailer is, and these two remaining wires, the white wire has an eyelet on it, that's for a ground. You want to connect this white wire to a good, clean ground, if there's one nearby. If not, they do include a grounding screw that you can make your own ground, and then the black wire's the power wire.That is what will run to connect to your vehicle's battery, and they do give you this extra length of wire to do that, and the butt connectors. Put a butt connector on your power wire, connect it to one end of this length of wire, run this all the way up to the front. When you get there, you don't want to connect this directly to the battery. You want to run it through this inline fuse holder. Take the other butt connector, put it on that length of wire, and then connect it to one side of the fuse holder just like that. Then on the other end of the fuse holder, you'll take this included eyelet connector, put it on there, and this is what will connect to the battery. Once that's all connected, pop open the fuse holder, take the included 15 amp fuse, push it into the fuse holder. Make sure it's in there all the way. Put your cap on there. Now your system'll be all ready to go. If you notice, they do give you some extra cable ties to take up any slack in the wiring.That should do it for the review on the Curt T-Connector Vehicle Wiring Harness with the Four-Way Flat Trailer Connector.

Comments

The most common reason powered trailer wiring converter harnesses fail is a short circuit somewhere in the trailer wiring. Before replacing the converter, youll want to closely examine the trailer wiring, beginning with the trailer connector itself. and working your way all the way back to the taillights. Look for broken wires, loose connections or wire with worn or cracked insulation that would allow the copper wire to ground out on the trailer frame or other metal component. If the existing short isnt located and repaired, you will continue to short out your wiring converter. Please see the linked article for more troubleshooting strategies.

Great harness and the plug and play was super. Longest part of install was running power wire up to the battery. Product shipped fast! Dealing with etrailer was a great experience and will recommend to my friends and family! 539383

etrailer is a fantastic company. This is the second time I ordered from them and the delivery is quick and the order is right. Everything fits up perfect. I highly recommend them. 488231

Overall I have not been too impressed with the quality of this product. l first purchased one in 2013 to install in our then new 2013 Dodge Grand Caravan and although the installation was easy, this product failed in late 2016. What I first noticed was the passenger side trailer light brake light was stuck when I connected the trailer to the vehicle. Even if the car was off and the vehicle lights were also off. Thus in early 2017 with my original Curt wiring harness out of warranty I just purchased another of these wiring kits from etrailer, installed it and everything worked. However, just a few months ago this newer wiring kit again failed in the same fashion. So I have not returned the second Curt C56331 kit I installed and just received a replacement one, under warranty, from etrailer. I guess I will go ahead and install it but if this third kit now fails, I think I will look for another brand. So overall, although I like the ease of installation, the quality of this wiring kit seems suspect. I do not think I should be on my third wiring kit within 5 years. One problem I think is there is no holes in the control box to affix it to the vehicle with a screw. Thus, it seems that at least the two times I have now removed this kit from the vehicle, the black control box has detached from the provided double sided tape and is swinging around loose. This is not good and may have led to the failure of this electronic box. I noticed that the other brand the etrailer is selling, the T-One product or whatever you call it, has a place where the box can be attached to the vehicle via a screw. Probably a much better way to attach it as at least with a screw, it is not going to come loose. So again the both times I removed this Curt C56331 kit from my vehicle the double-sided tape did not hold. So overall, I am not that impressed with the long-term quality of this item. I mean the first one I installed lasted nearly 4 years, not all that bad, but even that one I hope would last longer. Now the 2nd one I installed failed in less than one year, clearly not good. I guess I will find out how long this 3rd kit lasts soon! So for anyone looking at purchasing a wiring kit for their Grand Caravan, I would honestly recommend the other available product over the Curt Brand. 476589

Worked exactly as designed. Points that could be improved...1) the harness between control box an left turn signal is so short that it makes taillight removal very difficult (add 6" of wire, please). 2) the two sided tape needs to be upgraded. On my Town and Country, there were limited places I could mount it...all of them on vertical surfaces. I cleaned both surfaces with lacquer thinner before installing. The control box was dangling by the wire harness by the time I finished the install. Obviously, I'll have to find another way to mount it. 540319

Easy to follow video on website. Not to difficult to install. Would have been a lot easier if I had a lift and not working on my back on the ground. I would recommend this product and etrailer website very pleasant experience all around. 515973

The harness was well designed with none of the vehicle wiring needing to be cut or spliced. I installed this before the hitch, as recommended by another reviewer, and it gave better access to running wiring between the tail lamp assemblies. I took my time running the power wire forward to the battery and was able to find a nice clean route forward. The only thing I added was a protective cover for all the exposed wiring. I used 30 feet of 3/8" diameter black plastic split loom wire covering. I'm sure it would have been OK without this, but it looks good and makes me feel better about the power lead coming from the battery (always hot) running the whole length of the vehicle. 470177

Great product, very easy to install. I'm not a mechanic and did most without a jack using the double wall cardboard box it came in to slide around on. No problem installing videos and prepackaged parts etrailer puts out are easy to follow. Trailer light wiring was simple just jacked up one side of car for voltage wire. Very clean look will be great pulling my fishing boat and ATV up north. 495184

This was so easy to install. I just did what the 2013 Town and Country video said, except for putting the electronics housing upside down with the black silicone and wires facing up. That didn't seem right and I'm sure it would be fine, but I take zero chances. It came with everything I needed besides the electrical tape and wire strippers. It took maybe 10 minutes. Using a pull wire from the engine compartment was a great tip. There were just enough zip ties for the green slack on the passenger side taillight and to run the black to the battery. Everything is working great and I'm excited to hit the road. 555934

Easy to couple up with OEM connectors/wiring, but not always easy to fish into the correct cavity in the bodywork - I suppose that's the price for making the connecting so easy. On the whole, it's a significant improvement over how things were a decade ago. 597209

Perfect fit! Really happy I got this. Installing the wiring on the taillights was really simple. The hard part was trying to figure out how to run the wire to the battery. This took was a bit time consuming; it really helps to jack the vehicle up or put it on a lift if you have one. 567014

Great kit! Made an easy install to swap out of a botched UHaul install. Very happy with my experience. Most difficult part for me was removing light connectors from lights. Probably were messed up by UHaul too. I recommend 566383



- C56331

Pretty easy to install. Once you figure out where everything goes, the hardest part is routing the wire to the battery. It’s not hard, just takes a bit as you don’t want anything to hit it or fray the wire. I have used the lights a few times and everything seems to be working fine. 564388

I spoke with my Curt representative who tells me that as long as the install is completed as outlined in the instructions, there will be enough length in that passenger side harness to easily reach the tail light assembly on the passenger side of the vehicle. If you take a look at the videos I've linked, you'll see that there was plenty of wire length to reach the passenger side.

  • Recommended Wiring Harness and Hitch Installation for 2019 Dodge Grand Caravan
  • The Hopkins Fold-Over Mounting Bracket for 4-Way Flat Trailer Connector # HM48595 will fit the standard 4-way flat connectors on the Tekonsha # 118534 and the Curt # C56331. The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118534 is my preference over the Curt # C56331. Both will install in the same way, but the Tekonsha brand has less issues than Curt regarding wiring harnesses. Their converter modules just hold up better over time. If you haven't already...

  • Recommended Trailer Hitch Receiver And Wiring For 2015 Chrysler Town And Country
  • For your 2015 Chrysler Town and Country, I recommend the Curt Trailer Hitch Receiver Class III - 2", # 13364. The exhaust must be temporarily lowered for installation. Trimming of the fascia may be required. I've attached a video of this install for you. It does not come with the wiring harness. For the wiring, I recommend the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, # C56331. This is an easy installation of a 4-way flat trailer connector by plugging...

  • Trailer Lights Stay On when Connected to 2015 Dodge Grand Caravan with Curt Wiring Harness
  • If you are using Curt trailer wiring harness # C56331 on your 2015 Dodge Grand Caravan then those harnesses do allow power to the 4-Way even with the vehicle off. On a trailer that has LED lights the lights will be on brighter than if it had incandescent lights. You would want to disconnect the trailer when parked. I do not believe that you have a bad ground or a faulty converter box. This is a common characteristic of Curt powered wiring harnesses. The comparable Tow Ready harness...

  • Tips on Routing the Power Wire for Circuit Protected T-Connector Vehicle Wiring Harness
  • The best way to run the power wire to the battery on Curt Circuit Protected T-Connector Vehicle Wiring Harness, # C56150, is basically what is easiest for you while adhering to a couple of important safety tips. First, it is easiest to route the wire under the vehicle rather than through the inside. If you were to route the wire inside the vehicle, you would have to go to a lot of trouble removing trim panels or other components, in order to properly conceal the wire. Routing it under the...

  • Differences Between Curt and Tow Ready Trailer Wiring for 2012 Grand Caravan
  • Functionally speaking, both wiring harnesses do the same thing and would install in the same manner. The Tow Ready # 118534 has a slightly higher amperage rating than the Curt # C56331 and is a bit less expensive, so that's what I'd recommend. In this instance, you'd sacrifice nothing by going with the lower priced option. I've linked you to an installation video showing the Tow Ready # 118534 being installed on a 2012 Grand Caravan.

  • LED Indicator Light on Curt Trailer Wiring Harness Is On All the Time On 2013 Dodge Grand Caravan
  • The Curt trailer wiring harness for the 2013 Dodge Grand Caravan is # C56331. I could not find information on a 56187. The correct harness does not have an LED indicator light on it anywhere. There are some adapters, like # C57674, that have LED indicators to tell you a circuit is working on or not. In this situation the 12 volt indicator light will always be on because the 12 volt circuit is hardwired directly to the battery. In order to not have it come on it would have to be wired...

  • Can Trailer Wiring Converter Box be Placed Behind Tail Light on 2014 Chrysler Town and Country
  • There likely isn't enough space directly behind the tail light assembly for the converter box on your 2014 Chrysler Town and Country. I would not put it in that location anyway because the converters do generate some heat and directly behind a tail light assembly is going to be too confined. But you could place it just below the assembly. That way it isn't confined and it is more protected like you want. Like you said though you will likely not have enough slack for the green wire...

  • Trailer Wiring Harness Recommendation for a 2011 Chrysler Town and Country
  • I almost always recommend Tow Ready wiring harnesses because we hear about less issues with them than with Curt harnesses, especially the ones that connect to the vehicle battery. For your 2011 Chrysler Town and Country I recommend harness # 118534. It even costs a little less. We have heard far less issues from our customers with the Tow Ready harnesses. It will install the same way as the Curt harness but I did link a video showing an installation for you. You would not have to run...

  • Recommended Brake Controller Wiring Kit for a 2014 Dodge Grand Caravan
  • Your best option is to hard wire the installation kit # ETBC7 in order to utilize your Tekonsha brake controller # 90885. You will need to ensure you have a 4-way connector and or install one like # C56331. If your Grand Caravan has a 7-way connector then the installation kit # 5506 is the wiring kit you need. You can still follow the same relevant parts of the # ETBC7 instructions. The brake wiring harness plug won't be on the 2014 Dodge Grand Caravan because the harness wasn't...

  • Troubleshooting a Short in Trailer Wiring Harness on 2012 Chrysler Town and Country
  • The converter box on the Curt Wiring Harness, part # C56331 is to protect the wiring of your 2012 Chrysler Town and Country in the event of a short. Which is exactly what it sounds like you have. Some vehicles do not need the powered converter. To determine the source of your issue you'll need to determine if it's on the vehicle or trailer side. Does the fuse blow with the harness connected to the van but no trailer plugged in? If so the issue is on the van. If you need to plug...

  • Does the Computer Have to be Flashed on a 2012 Chrysler Town and Country to Install Trailer Wiring
  • Both wiring harnesses for the 2012 Chrysler Town and Country, see link, are T-connectors but also need power from the vehicle battery in order to power the trailer lights. The T-connections provide the signals that tell the converter what to do. This method protects the electrical system on your van. Because these harnesses require a battery connection, you will need to disconnect the negative cable when wiring in the harness. Having the battery disconnected will essentially re-set the...

  • Trailer Wiring Harness for a 2012 Chrysler Town and Country
  • Manufacturers have determined that the 2012 Chrysler Town and Country requires a powered wiring harness. this is because the vehicle's sensitive wiring is not designed to handle the additional power draw of trailer lights. A powered harness gets power for the trailer lights from the vehicle battery to further protect the vehicle from overdraw and from shorts from the trailer wiring. I recommend wiring harness # 118534 which works well with the Chrysler Town and Country. I have linked...

  • Curt Trailer Wiring Harness for 2014 Chrysler Town & Country has No Power
  • Check the fuse for the power wire in wiring harness # C56331 for your 2014 Chrysler Town and Country. If that fuse is blown or missing that would be why the harness is not working. Also make sure the white ground wire is attached to a bare metal surface; no paint or coating between the ground and where it is connected. If that does not do the trick then you can test the converter to determine if it is bad. I have included a link to a video that shows how to do this.

  • Can Wiring Harness be Grounded in Way Other Than Directed
  • You should only ground the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56331 as directed by the manufacturer. That means when installing it you have to ground it to the vehicle frame and ensure it is free of any type of dirt, paint or corrosion. Failing to do this can result in all types of funky issues; problems with a poor ground are the leading cause of harness issues and you are definitely going to want to follow the manufacturer's directions as closely...

  • Troubleshooting Trailer Wiring Harness C56331 Installation in 2014 Dodge Grand Caravan
  • Thank you for your purchases from etrailer. I suggest you re-check your ground wire connection. It can happen that a weak ground will pass enough current for some light functions but not others. Turn signals that blink on and off will draw less power than the brakes, which remain illuminated as long as you step on the pedal. You can try sanding off any paint/primer that may remain on the grounding point to enable a better connection, or you can relocate the ground terminal to a new spot...

  • Wiring Harness Keeps Blowing Fuse Inside Vehicle
  • It sounds like something is causing a short circuit in the wiring of the Curt harness you mentioned in your question. I recommend checking all of the connections the harness is making to your vehicle to see if there is anything out of place that may be causing a short. Look for damaged or frayed wires, any wires that are touching bare metal or two wires that are touching each other, wires attached to the wrong location or any corrosion along the wiring. Any of these things can potentially...
