    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily
    • Locate connection points behind tail lights
    • Plug in T-connector
    • Run hot lead to car battery

  • 1-Year limited warranty


This custom-fit T-One connector plugs into your Dodge Grand Caravan'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.

T-One Connection Location Points Behind Tail Lights

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 and insert the provided fuse.

Once installation is complete, the 4-way flat connector will be stowed beneath your Dodge Grand Caravan, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.

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.

ModuLite Power Module

A ModuLite power module is built into this T-One connector. With a ModuLite, your trailer's lights will be powered without overloading your Dodge Grand Caravan's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

Video Transcript for Tow Ready Custom Fit Vehicle Wiring 118534 Review

Today we're going to review part number 118534. This is the Tow Ready T-One Vehicle Wiring Harness with the 4-Way Flat Trailer Connector. This is a custom fit part number. It is designed to fit the Chrysler Town and Country and the Dodge Grand Caravan starting in 2011. What I would recommend for you to do is go to our website, use our fit guide, put in your year and model vehicle and it'll show you that this part will work for your application. Now this does provide a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights. It does connect very quickly and easily, it uses these plug in T-connectors and basically what you do is just locate your connection points behind the tail lights, plug them in, you run a power wire for the ModuLite module, a ground wire and then you'd be ready to go.

Now it does include this ModuLite right here. It's a powered module that connects directly to your battery and avoids overloading your vehicle's electrical system. Now the length of wire that the 4-way is on that runs out the back, it is a 16-gauge bonded wire and it actually on the 4-way itself, you can see it has this integrated dust cap which is nice when you're not using it. You just put the cap on in there and it will protect your terminals from any damage or from the elements. A few specs on this harness. The maximum amperage for the stop and turn light circuit is 4.2 amps per circuit. On the tail lights it's 7.5 amps per circuit.

Now this part comes with everything showing here. It comes with the wiring harness, it comes with some cable ties to take up any slack in the wiring, a couple of buck connectors, an eyelet connector, a grounding screw, a 15 amp fuse, an inline fuse holder, a length of wire and some nice detailed instructions that show you where the connection points are and how to connect all these. Quickly here, I'm just going to show you how this does connect. What you would do is go to the back of your vehicle and then what you'll do is go behind the tail lights on both the driver's and passenger's side and what you'll do is, let's say we'll start on the driver's side. You'll take this T-connector that has the yellow wire in it and that's for your driver side. What you'll do is go behind the tail lights, unplug them and these will tee 00:02:08 into that harness and then what you'll do is go and take this length of green wire that has the extra length of wire, that's for the passenger side.

You'll run this over to the passenger side and do the same thing, unplug behind the tail light, plug this in, once the T-connectors are all plugged in, then what you'll want to do is you'll have this white wire coming out of the ModuLite here, it has an eyelet on it. This needs to get connected to a good, clean ground. If there's a screw on your car that you can connect this to to get a good, clean ground, you can do that. If not, they include this grounding screw that you can install your own ground. Then the other wire is this larger black wire.

Now that's your power wire. This has got to the battery in your vehicle. That's why they give you this extra length of wire. What you'll want to do is take one of the butt connectors, put it on here, attach one end of this wire on that and then run this length of wire all the way up to the front of your vehicle to where your battery is. Once you get up there, you'll take the other end, take the other butt connector, put it on there and you don't want to connect it to the battery yet. What you'll want to is take this inline fuse holder and go ahead and connect that to this wire. Then what you'll do is on the other end of this inline fuse holder, you'll take the eyelet connector, install that and then this is what will connect to the positive post of your battery. Once that's connected, just pop this open and they include a 15 amp fuse. What you'll do is go ahead and install that in the fuse holder. There you go. Put your cap over it and then you'd be all ready to go. Like I said, you'll have some extra cable ties here if you got some length of wire right this far who needs to be tied up, you can use the cable ties. That should do it for the review on part number 118534. This is the Tow Ready T-One Vehicle Wiring Harness with the 4-Way Flat Trailer Connector. .

Installation of this wasn't too bad. The instructions are pretty good and there are some decent diagrams. However, I've got say that I was surprised and disappointed that I had to run a line from the tail light all the way to the front of the vehicle directly to the battery. I've done of these before on an older model Grand Caravan and it was all installed in the rear. However, it seems like all of the wiring kits for this model are like this, so I assume there's a good reason for it. Anyway, I've got two bits to offer. First, I don't believe that it's good practice to have a single wire exposed to the elements, like the road, debris, heat, etc. Because of this, I bought some of the split plastic loom stuff that's very common. I used 1/4" split corrugated tubing, part # 7840K81 from McMaster-Carr. It's currently $1.94 for a 5' length, so it's pretty cheap. I bought (4) 5' lengths and used it all. FYI, I already had the line run and put the tubing on after. If you do it right, it's not bad to do, but obviously you'll have to cut any zip ties if you already did that. Second, I didn't run the harness between the tail lights on the outside, I ran it on the inside. If you feel around in the driver's side tail light cavity with one hand and the inside of the jack cavity from the back, you'll feel a "bulkhead" kind of a barrier part that you can push out. Then you can run the harness on the inside. The black plastic piece that runs on the top of the door jam (above the bumper) just pops out, as do the clips that hold the fabric down. Run your harness under that fabric. Pull the panel aside a bit on the passenger side and look for the same "barrier" part in the tail light cavity and run your connector through that way. I *don't* have a lot of interior experience in cars and I thought this was pretty easy. Good luck..... 82097

Product arrived promptly, and as described. Instruction sheet has an error, as it shows the Module being mounted in the tail light visible area on my 2013 Chry T&C . The green wire is too short Follow the VIDEO (!) , except, do not mount the module until you have the right hand tail light sockets done. (and leave handling length !) The GREEN Wire is too short to do that ! Had to remount the module down below the open area, about 6-8 inches lower in the cavity in order to plug in the sockets on the right side light. Also found vent flaps from the car jack area, so was able to feed the trailer socket and wire into the jack storage through this vent. Now the trailer plug is inside and only exposed when using a trailer by letting the door weather strip close on the wires. Used 3/8" flex cover (plastic conduit) from Home Depot so all wires are protected from the heavy winter snow undercarriage we get here up north. I think it is a very nice kit , and the wire ties included show the good thought that the manufacturer put into it. Too bad the green wire skimped on length about 6-8 inches 121126


Good Product, very satisfied. Well worth the time and cost. Would buy again if I get a new car

Yes, I found the same thing, the green wire is about 12 too short when installing on a 2013 Grand Caravan. Very annoying.

My hitch installation went well. The wiring kit installation, however, did not. The wire that goes from the left rear lamp to the right rear lamp was about 12" too short. The black wire that goes to the battery was about 6' too short. In trying to figure out what went wrong, and then making about 3 trips to the auto parts store, and then splicing in additional length of wires, I spent pretty much the whole day completing this project. My suspicion is that the wiring kit was a returned package. The plastic enclosure was taped closed and the black wire inside was not neatly wound, like a new wire would be - and like what was shown in the picture on the instruction sheet. If that is the case, I would like to recommend that you do not sell returned wiring kits unless they are completely inspected, including measuring the wires. The job is done, it just took alot longer than it should have and cost me a little more than it should have. 129954

Installation went great, made possible by etrailer's instructional video (search YouTube for "etrailer wiring 2013 town and country"). Without the video, installation would have been much more difficult as the written instructions that come with the wiring kit are not very good at all. Like is stated in the video, you will need some additional zip ties that are longer than the ones supplied in the kit. 130091


No problems!

Design of the harness made it very simple to place in my vehicle. I am assuming that the need for a separate fused connection to the battery has provided the trailer circuit with a separate supply so that if a fault occurs, there will be no loading of the vehicle circuits. (Instructions do not discuss this situation.) Installation instructions were adequate, but video available on the web made it fool proof. Green wire from left to right assembly was a bit too short, but easily corrected with a 10" splice. Running the power wire up thru the space in the engine compartment required a bit of planning to miss any moving steering or drive components, but tiewraps made clearances proper. I haven't checked out the trailer lights yet, but the connection has not interfered with my vehicle wiring. If the trailer lights work I will consider this an outstanding product well worth the cost. 26924

The product install videos for the wiring harness and the hitch are what convinced me to do it myself and SAVED ME over $350.00 from the price the dealer was quoting me. These videos are excellent and I had no trouble at all with the installation by carefully following the advice given on your online videos. Re: feedback on the green wire from driver's side taillight to passenger side taillight... I ran it first and reinstalled the passenger taillight back in place BEFORE I adhered the circuit module inside the driver's side taillight compartment to ensure that I had enough slack on the green wire (other reviews noted that they had to splice the green wire to make it long enough). Everything else I did exactly by your install videos and I'm on my way! Thanks for the huge savings $$$ Cha-Ching!!! 41118

For my 2014 Chrysler T&C, I ordered the Curt trailer hitch with 118534 wiring harness with regular free shipping and received them the NEXT day. That is impressive and was unexpected. I installed the hitch with no difficulty, assisted by an hydraulic lift. The instructions were helpful and straight forward. I did have to release the 3rd muffler clamp for access. My only concern is the part/opening that receives the ball assembly, presses on the plastic bumper shell. The instructions do indicate some modifications (cut) may be required. I did not modify. This made pulling the taillights out (for the wiring harness) a little harder. Instructions for the wiring harness were ok. However, I found a U-tube instructional video (thru e-trailer) was most helpful. Many thanks. 179335

The poor rating is not for the product by itself but as it relates to a particular vehicle. This wiring harness was purchased for a 2014 Dodge Grand Caravan. The package labeling stated it was for a 2011 vehicle. The 2011 caravan is smaller than the 2014. The green wire to the right side is too short. Yes – I read the other comments that said as much but, I thought I was “smarter than the average bear” and would be able to make it fit with proper placement of the module. It fit – just barely. It was so tight I thought the wires would pull out of the connectors so in the end I spliced in about 10 inches. E-trailer really needs to get/sell an updated version of this instead of selling a 2011 version for the newer vehicles. 143183

First, I want to compliment for their excellent customer service. I received notification that my order had been received and was shipped, along with tracking, shortly after placing my order. I received the item in a reasonable amount of time. The item itself is exactly what I needed, at a fair price, with reasonable shipping fees. I have already installed the trailer light wiring kit using the directions provided and the "you tube" video. The installation was relatively easy, and the kit included everything required to complete the job. Everything has been tested and works perfectly. Overall, GREAT job and I will certainly keep in mind for future purchases. 175029

I liked being able to watch the video to know what I was getting into. Laying on my back under the vehicle was a bit more difficult than the video. I added some loam (covering) to the green wire as I routed it around the bumper up into the tail light area. Looked like a good pinch point/rub area. I added 10" of wire to the green cross over wire to improve the routing through the rear bumper. Definitely need more zip ties in the kit. They are cheap. I also added 12" of loam to the 4 wires as I routed over the hitch and rest the connector in the bumper cover. Makes it more rigid so it doesn't fall down. Overall I am satified with the final product and would do it again. 79152

by: Donn F12/22/2014

I found it easy to install behind the tail lites. Three problems though... 1. The green wire that goes to the passenger side tail light was about 4 inches too short. No matter how i tried to route the wire it was just too short. I soldered a 6" jumper in there and the problem was solved. 2. Running the black wire (it should be red by the way) to the positive (+) terminal of the battery was a real pain in the ass. Figure out a way to tap in to 12 volts another way please. 3. There was about 10 zip ties in the bag. I used all of them and about 25 more of my own. I am glad i had a bunch in my shop. The end result was it worked the first time. 166518

This is the third Grand Caravan on which I have installed a trailer hitch and wiring harness (02, 05 and 12). The 02 and 05 hitches were purchased from Chrysler and the 12 from you folks. This is the first time I had to run a wire from the tail light to the battery. I watched the video and I knew what I was getting into, but I never thought it would be so much trouble to install that wire. I don't know how they do it, but all I had to do was plug in the "T" connectors. Your price really attracted me, but in retrospect, I think I would rather have paid a little more for the harness. The hitch went right on. Great price. 74910

After installing a receiver 13364 with my 12 yr old friend David, we were ready to install the wiring harness. In the past, I've always bought the el-cheapo kits that were available and dug around in the van wiring harnesses looking for the correct wires. Very time consuming and a lot of knowledge needed. This kit is a very reasonable price and as complete as they can get. After reading the directions, David did most of the work and enjoyed every minute of it. A perfect learning experience for a boy, which was both thought provoking and fun. It works as designed and the installation doesn't get any easier than this kit. 63574

The connections to the tail lights were perfect. I had no problem with the length of the passenger's side green wire as others have metioned. The control module mounts nicely on the slanted part of the driver's side inner tail light wall. The challenge was working in my driveway with out a lift when it was time to install the long black wire to the positive side of the battery. I only had the scissor jack from the van. I am a little weary of running the power wire under the van. I think this is the place where the wiring harness will fail in the future. The total install time for me was 2 hours. 90122

by: Dwayne Missouri05/14/2014

I have not hoo me ed it up to a trailer yet, but the product is exactly as advertised. I utilized the convenient video provided by and had it put in properly in no time. The only thing I would suggest is that the manufacturer provide more than one battery connection loop and more than one wire quick connect. The ones provided slipped off and I had to run up to the store to get more which required me to put the project, tail lights etc., back on the car so I could drive safely. Even with this hick up I still had it fully installed with in 2 hours. 130717

by: Mick S06/01/2015

The product arrived faster than promised and exactly as it was described on their web page. After installing the wiring I have to say that the instruction videos are very accurate. It helped me a lot to complete the installation. It is really easy if you follow the instructions. I have a Chrysler Town and Country and since this wiring set is designed to be installed independently from the vehicle system my mini van electronics are working perfectly. I tried the connection already and it is working fine. I am very happy with this product. 199649

by: David K11/21/2011

Great instructions with the kit. The green lead to the passenger side could be longer though -- the shortest route is a bit tight around corners. 27261


I too found the green lead short, when following the package directions, and installing the module behind the left taillight, instead of below the taillight, as the installation video shows. It took me an hour to get more wire, splice it, solder it, and install it. Please change the packaging instructions so others do not do what I did. Otherwise, install was quick I used more larger zip ties.

Install was pretty simple, took about an hour. This kit was thought out and tested, this was obvious when you find that all of the wire lengths are perfect. One piece of advice, when removing the connector from the light assembly, slide red piece up, then press the black piece that was under the red slide, once you figure this out it slides apart easily. I am not a big fan of butt connectors, typically I solder wires together. I did use the butt connectors, but, I will probably go back and solder them together. 74753

by: Jay Love09/06/2011

Instructions are very clear. Everything is exactly the right length; for my Grand Caravan there is about 12 inches of lead from the bumper to the trailer hook up. Perfect! I chose to run the black power lead inside the car, up the driver's side, instead of underneath as shown in the instructions. I ran the wire through new holes I poked in the taillight wire gromet and then through the hood latch gromet, upper left side in front of driver's feet. Easy to install and works great!!! Thank you 23609

by: Jim M.04/23/2013

This wiring harness worked perfect. I read a review which stated the green wire wasn't long enough. Mine was. I routed & hooked up the green wire BEFORE mounting the control module & before I wire tied the harness to anything. This method provides all the slack you need for a perfect install. I recieved an email with tracking info and the items were in my hands a couple of days ahead of schedule. The people are knowledgeable, friendly & effecient. I will definitely do business with them again. 77535

by: Ron A09/13/2012

OOPS! I guess I reviewed the wiring harness with my hitch review. The harness was also easy to install, just as your video showed. I read some reviews that said the green wire going to the right tail-light was too short. It wasn't. One has to adhere the box under the left tail-light, and then the wire has an inch or two to spare. It would be hard to send a photo of the wiring, as I did with the hitch review. Good price, short delivery, easy installation. Couldn't be more satisfied. 54613

- 118534

by: John R.05/05/2013

This was very easy to install. The wire to the passenger side just barely long enough to reach, so plan your positioning well. I haven't tried it on a trailer yet, but I expect it will work perfectly as all my vehicle lights do. Overall I'm very pleased with my purchase and the hidden hitch trailer hitch was very easy to install just as the videos illustrated. I I talked the hitch and harness in less than an hour with even jacking up the vehicle. 79069

I'm not really sure about this one! The last T-One wiring kit we ordered a couple months ago was a whole bunch less complicated than this one is. There seems to be as much wiring in the package as is on the vehicle, but I understand. The newest vehicle is a '12 with LED lights, etc. I installed the hitch but will wait for my wife's assistance to do the wiring! I'm sure it's not that difficult but, as a man, I am NOT allowed to read directions! 47698

by: David C.06/16/2013

The wiring harness was good. Had doubts after I read the other reviews that complained about the green wire being short. I did not have that problem. My problem was finding a good path for the wire going to the battery.. The double sticky patch on the black box really sticks.. just touched it to the car body and it was permanent. Drove across town to try it on the trailer and found out I forgot the fuse! Glad I found this site.. 84876

by: Joe G.12/16/2014

The kit was flawless and easy to use....except for one important problem----- the green wire leading to the connection on the passenger-side tail light was too short. I had to splice another section of wire into the green wire to give it enough length to fit. Service was great, the rest of the product worked as advertised--- but if it doesn't have enough's a problem. Hopefully this will be addressed. 165656

Good product, great service! This is my 2nd purchase made here. I traded my Kia Sedona in for a Dodge Grand Caravan; therefore, the repeat. The Hidden Hitch hugs the rear seat fold-in so well that there should be no contact with the exhaust at all. I have yet to use it with trailer, but do not expect any problems. I buzzed out the electrical and all was working. Sorry, no picture yet. 141304

by: Cameron W.07/10/2014

The wiring harness was fairly simple to install, but the instructions were vague in spots and didn't have the correct information for our van on some of the steps. I've done these before, so I knew what to do in general. All the parts needed were in the kit and the wires were long enough and the plug-n-play connectors worked well. Wouldn't want to wire up a new vehicle any other way! 140627

- 118534

by: Tom R.04/02/2015

Pretty straight forward product but I used an alternative mounting location under the car for the box due to wire length. I recommend you do the same to avoid having to short of wires for the trailer and passenger light. Running the power cable to the battery was relatively easy along the underside of the body and then fishing it up through the gap at the driverside door. 182388

by: Russell S.04/24/2014

This trailer wiring was easy to install. My son and I did it in about an hour. Watching the install video gives you the confidence and knowledge to do this yourself. The "T" connection prevents from having to cut any wires. Just run the wire and connect both tail lights before sticking the power module and ground wire to make sure you have enough wire. 127198

- 118534

by: James California01/24/2014

This by far was much easier than I thought. I will add though that the passenger side tail light connection was a bit short. The green wire could have been about a foot longer. Also since both wires would be exposed I ran the power wire inside under the interior trim of my 2011 Dodge Grand Caravan and also chose to use wire loom to protect them. 114653

by: Robert L.09/03/2014

What a great setup! I had no problems at all. Everything was the right length for a 2012 Dodge Grand Caravan. More zip ties would be nice. Note that like it says in the video, there isn't a nut for the battery post connection. In my case, I just split the ring terminal with my dikes and slipped in under the clamp nut for now until I can get a nut. 149890

Harness fits great and it installed quick! We paid close attention to routing the wires and everything fit very well on our 2012 Dodge van. NO modifications required. Please include a few more tie wraps to ensure everything is securely in place. I would highly rate this product and the service that supports it. Thank you. 159310

WHY DON'T YOU ADD ANOTHER FOOT TO THE GREEN WIRE THAT RUNS TO THE PASSENGER SIDE TAIL LIGHT. ALMOST EVERY CUSTOMER REVIEW I READ MENTIONED THAT IT WAS A LITTLE TOO SHORT. Other than that, I Found your T-One wiring harness on youtube and reviewed the installation video. Followed the enclosed directions for an easy install. 131934

Nice product, difficult install but not because of hitch. my car had a handicap ramp conversion by VMI. They moved spare tire from under middle of car to accommodate ramp. They lowered fuel tank and installed a metal box for spare in floor above tank. Box required trimming to allow room for hitch on right side and rear. 165747

the green wire in this kit is to short (about 10 inches) had to splice the wire in order to plug in the passenger side tail lights. other than that it was an easy install. But add some more green wire length. just lucky I had some of the same size wire in my garage to complete the job. thanks harold dudley 38528

Great product, easy to install, green line to passenger side should be about 9-12" longer. Have purchased several items from E-Trailer and have found the service and support to be outstanding. This item was ordered on a Saturday morning and received early on Tuesday. You just don't see that kind of service. 88847

I have installed a few of this style wiring harness on my other vehicles. I received the harness within a few days after ordering and it installed fairly quickly. I tested things out and everything works great! I would be happy to recommend this item to anyone looking to add trailer wiring. 48073

I suggest during install run the wires to the passenger side before mounting the black box on the driver's side to be sure there is enough slack. My only criticism would be for the manufacturer to provide more and longer cable ties. I happen to have some on hand so no big deal. 133315

This product works great and was relatively easy to install on my 2012 Dodge Grand Caravan. It takes a few minutes to run the wire underneath the car to the battery in the engine compartment. The work to install around the tail lights is extremely simple and straight forward. 160060

works good. installed inside van under door thresholds and throu firewall at hood release gramlet to battery.install time about 1 hour give or take. green wire side of harness could be about 12 inches longer but it just was long enough to make passenger side. 99759

This wiring was a good package and was delivered quickly. The install was also well described. Routing the wire from the taillilght to the battery terminal was a little tricky (but would have been easier if I had been able to put the car on a lift). 88050

It is a strong well built hitch, along with the wiring kit, was all attached to the 2013 Town and Country with no problems. Works well. Minor setback was the hitch was apparently bent a little and needed a little reshaping to fit the frame. 149605

Everything installed in about an hour. However the side that was ran to the pasanger side was about 3 inches to short. Cutting and splicing a brand new wiring harness isn't my idea of a good time. But it works so enough said, got er done. 219521

I had no problems with this install on a 2014 town and country. The wires were all long enough unlike what some other reviewers said. Extra zip ties will be needed to do it right. Other then crawling under car everything was great. 154919

  • Actual Towing Capacity of 2012 Dodge Grand Caravan without Tow Package
  • From what I have read online, the 3600 lb towing capacity is listed as the max for vehicles that have been properly equipped. What Dodge means by properly equipped is not entirely clear. It could simply mean that it has been equipped with a hitch and wiring, or it could mean that the vehicle has a transmission cooler, special gearing, heavy duty transmission, etc. What a tow package consists of varies greatly from manufacturer to manufacture, and can even vary across their product line.

  • Differences Between the Class III Hitches For the 2012 Dodge Grand Caravan

The Hidden Hitch Class III 2-Inch Hitch, part # 87451, the Draw-Tite Class III 2-Inch Hitch, part # 75579, and the Curt Class III 2-Inch Hitch, part # 13364. The Hidden Hitch and the Draw-Tite are the same hitch made by Reese, just different part numbers. All three of the hitches are a square tube design and will install in the same location on the vehicle. So they will all look the same on the rear of your...

  • Installing a Brake Controller on a 2013 Chrysler Town and Country
  • There will have to bee some cutting and splicing to install a brake controller on your 2013 Chrysler Town and Country. Chrysler did not add a factory brake controller harness to the Town and Country, so the brake controller will need to be hardwired. The good news is that you will likely only have to splice one wire into your vehicle wiring. To install a brake controller like the Curt TriFlex, # C51140, that you referenced, you will want the Curt Universal Brake Controller Wiring Adapter,...

  • On some vehicles that the CURT Trailer Hitch, # 13364, is designed for, there can be some components that require the cutout in order for the hitch to fit and/or to manipulate the heat shield behind it. Even though there is a cutout, it does not change the capacity of the hitch which is 400 pounds tongue weigh, 4,000 pounds gross trailer weight. I have included a link to the installation details and a video showing a typical installation. The difference between the CURT hitch and the...

  • Trailer Hitch, 7-Way Trailer Wiring Harness and Brake Controller for 2012 Chrysler Town and Country
  • First, lets start with a trailer hitch. The most popular hitch for your 2012 Chrysler T and C is Hidden Hitch model # 87451. This is a Class III trailer hitch with a 2 inch receiver. I have linked a video showing a typical installation for you. Since you plan on doing some towing I also recommend the etrailer ball mount kit # EBMK4EL. It comes with a ball mount, interchangeable ball set, a hitch pin with clip, and a storage bag. For trailer wiring, in order to add a 7-Way you must...

  • 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...

  • Hitch Recommendation for a 2014 Chrysler Town and Country that Doesn't Require Fascia Trimming
  • Draw-Tite trailer hitch # 75579 will fit all models of the 2014 Chrysler Town and Country. There should be no bumper fascia trimming required. The only trimming mentioned in the instructions, linked to the right, is possibly on a mudflap. I have also included a link to a video showing a typical installation for you. The Curt Hitch part # 13364 that you referenced would most likely require you to trim the fascia so I would not recommend it for you. If you plan on doing some towing...

  • Comparing Length of Curt and Hidden Hitch Trailer Hitches for a 2013 Dodge Grand Caravan
  • On the Hidden Hitch trailer hitch # 87451 when we installed it on a 2013 Dodge Grand Caravan it measured 6-1/4 inches from the center of the hitch pin hole to the back of the rear bumper. We then installed Curt trailer hitch # 13364 on the exact same van and it measured 4 inches from the hitch pin hole to the back of the bumper. So the Curt hitch on this vehicle does come out a little further. For either of these hitches the recommended ball mount is # 2753 and it measures 9 inches from...

  • How Difficult Is Installation Of Trailer Hitch On 2014 Dodge Grand Caravan
  • The attached video for a 2014 Dodge Grand Caravan shows where the locations are on the underside that need to be removed. These are installed at the factory, and should all be in the same locations as shown in the video. This hitch comes with installation instructions and should be a really simple install. I doubt you will have any problem. When you see the spacing for the bolt holes on the hitch you can see where they are on the underside of your van. It does require using a torque wrench...

The linked photo shows both the female and male T-connectors used in this harness. If these connectors match those on your vehicle then this harness will work for you.

  • How Does Curt Trailer Hitch 13364 Install on a 2014 Dodge Grand Caravan and is Trimming Required
  • Curt trailer hitch # 13364 has 2 bolt holes on the passenger side of the vehicle because the forward most bolt on the vehicle is there holding on the vehicle bumper and Curt decided this location was not necessary to safely secure the hitch to the vehicle. It looks like all of the hitches use just 2 fasteners on the passengers side. Trimming might be required on the Town and Country vans according to the instructions, linked for reference, but the 2014 Dodge Grand Caravan is not mentioned....

  • Installing 7-Way Trailer Connector and Brake Controller in 2014 Dodge Grand Caravan
  • To install a 7-way trailer connector on your van, you'd first install a functional 4-pole connector, like part # 118534. Once that's installed, you can install a 7-way by plugging the # 37185 adapter into the 4-pole. Once the white wire is grounded, the lighting functions on your 7-way will all be functional. If your trailer has electric brakes, and you want them operable you'll need to install a brake controller. For a basic but easy to use controller, I'd recommend the Tekonsha Primus,...

  • Towing Setup Recommendations for a 2014 Dodge Grand Caravan SE

The Hidden Hitch part # 87451 that you referenced would be an excellent hitch that has similar capacities. I attached an install video for this hitch for you to check out as well. Now a weight distribution system is a hitch that distributes some of the tongue weight on the hitch to the front...

  • How Far Will Hitch Pin Hole of Curt Hitch # C12264 Be Recessed Under Bumper of 2014 Grand Caravan
  • When we installed the Curt # 13364 on a 2014 Grand Caravan, we found that the receiver was recessed under the vehicle so that there was four inches between the hitch pin hole and the furthest rearward point of the back bumper. According to Curt, the receiver tube on the Curt Class II # C12264 is of the same length as the 13364, so it should also be recessed by 4 inches. If you'll be using the hitch for towing, you'll also need a trailer wiring harness, part # 118534, a ball mount,...

  • Tail Light Fuse Blows on Chrysler Town and Country with Tow Ready T-One Harness Installed
  • I'm sure you are already aware of this, but the M17 fuse is the fuse for your left tail light and license plate light. Since the fuse keeps blowing when the Tow Ready T-One Wiring Harness, # 118534, is installed and it does not blow when the harness is removed, then that is a pretty good indication that the harness is the problem and it should be replaced. There is a good chance that the converter box shorted out causing the fuse to blow. A new wiring harness will most likely fix the...

The ball mount is not included with the Draw-Tite hitches because we pair the ball mounts with the Hidden Hitch models instead. If you are also interested in trailer wiring harnesses you can use # 118534.

  • Differences Between Curt # C56150 and Tow Ready # 118534 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 # C56150 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.
