  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • No 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.


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 behind tail lights
    • Plug in T-connector
  • Comes with dust cap for 4-way flat connector
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side 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 beneath your vehicle, 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.

I was very pleased with the ease of installation of this product! No poking wires with test light needed! No cutting and splicing wires! No standing behind the trailer saying "No the lights not on"??. Just unpackage item,remove tail lights from vehicle,unplug each lights "male and female" connections and insert the new connections that come on this wiring harness! Zip tie up any hanging wires! So much easier and a no stress! I highly recommended this product and the employees here are great! They took the time to answer all the questions I had with no problem. If you need to install a wiring harness for a trailer this is definetly the way to go and the business to buy it from! Any vehicle in the future I need to add a trailer wiring harness to, this will be the place I turn too

Dodge Dakota trailer wiring harness ins talled




by:

This product (item #55323) is very easy to install. I found multiple videos on YouTube and the instructions are just as easy to follow. All I needed to do was clip some wires together and that’s it! No splicing necessary which is what I was looking for. I signed up for the cheapest shipping method and it still showed up here in Minnesota a couple days early. Now I can actually have working lights on my trailer! Totally worth the money and I will be shopping etrailer.com more often! Thank you!

I bought one a few yrs back for my 2000 dodge Dakota. They worked Awesome intal I got rear ended. I pick up another dodge Dakota. I took my old ones off for my next truck. But didn’t match up.
That’s ok.. Yes they worked great & easy to intal.
so I called etrailer ordered another set.
2-3 days later & 5 minutes to intal
Happy Camper. Plug & play that’s it.. well Recommend... Happy trucking
Thx etrailer ??

So far so great super easy install with the hitch and wiring harness. Great price and fast shipping I will be back for all my trailer needs. Thanks guys.

Bought this a year ago... works like a charm... easy hook up. Had it working in under an hour.

Great product haven't had the chance to install it yet but will only take like 5 min to install.




by:
2005 Dodge Dakota

Performed exactly as advertised on my 2005 Dodge Dakota. Although the vídeo wasn't super helpful with specifics (like the vídeo for the hitch intall, which was perfect), it's pretty easy to figure out. I got a little bit ahead of myself and unplugged ALL of the tail light connectors when in fact I only had to unplug one on each side. On my Dakota, each side has two separate bulbs and therfore two connectors. The bottom bulb and conector are only for the White backup light and there is no such conector on the trailer wiring harness therefore no need to mess with that conector. The top bulb and conector are for the running lights and blinker/brake light. Therefore, you only have to unplug that top conector and insert the conector for the trailer wire in it's place. Last trick, at least for my Dakota, the tail-light lens module comes off by pulling it straight back towards the rear of the truck and at first it seemed like it would never let loose. I almost broke one of the alignment pins by attempting to twist or pivot the lens module and it would have been better to find a way to pry it off by pulling straight toward the back of the truck rather than pulling out to the side. The trailer wiring harness was a perfect fit for my Dakota and worked perfectly once installed, no cutting or splicing of any kind was necessary. The only other thing you may want to do is buy some dielectric grease to prevent corrosion in the contact points of the connectors. Most auto parts stores sell a single use packet of dielectric grease for about $1.79 on a rack near the cash register along with single use packets of caliper pin grease, silicone grease and other special lubricants.


Comments
We actually offer a small tube of dielectric grease as part #496971. Dielectric grease works very well for keeping moisture and corrosion out of electrical connections.

Fit perfectly. Installed the trailer hitch receiver by myself in about an hour but was no easy task (had no help).
The trailer wiring harness installation info could have explained the installation a little better but worked as described.

Still working great!

I haven't been able to test the product with a trailer, but I can easily write a review about the installation and etrailer's efficiency.

Etrailer processed the order and had at my door within three days. The product was packaged very well, and etrailer's communication was top notch. The kit installed with very little effort, and etrailer's installation video was perfect.

I will definitely come back for future trailer related needs.


Comments
Honestly, I never had to use it. And I just sold the truck last week. Thank you for following up. Shows great customer service.

Had the harness in two days and it was exactly as advertised. Instructions were just a skosh bit fuzzy but that's probably because I'm on the downhill side of 78. Only problem I experienced was popping the plastic "rivets" out of the bed panel while removing the tail light assembly without breaking the lens. Works great and had it done in less than an hour. Thanks

I no longer have the vehicle but everything I have ever purchased from you folks has been really good.
Chuck S - 06/08/2017



by:

The kit appeared very well made, good materials. It was very simple to install (using the well-written instructions). I tested my lights before applying the tie-wraps and it functioned perfectly, so I applied the tie-wraps, and was finished. It took me about 45 minutes total. Not bad at all. Good product, reasonably priced, well made, and easy to install.

Works great after a year

The wiring harness fit perfectly, it installed easily and worked without any problems. I am very satisfied with it and the entire purchase.




by:
2004 Dodge Dakota

Easy install in a 2005 Dodge Dakota; took about 40-minutes. Pay attention to labeling on connectors for driver's side vs passenger side as pertaining to correct turn indicators. At $[XX]including shipping it is a much better price point than paying some installer between $[XX] - $[XX].




by:
2007 Dodge Dakota

Couldn't be more pleased. I ordered Sat and didn't think it would ship til Monday. Then got your email that it shipped Sat. The harness is a breeze to install and works perfect. Great product.


Comments
Still working great. Have recommended it several times.
Robbie G - 04/19/2018

Very easy installation: required removing 4 screws. Wiring harness connects securely to existing connectors and entire job completed it 15 minutes with a fully functional setup (Turn signals, brake lights and running lights). All connections are protected inside tail light panel openings.
Recommendation: DO NOT MESS WITH THE MICKEY MOUSE "CLIP ON" WIRE HOOKUPS! Get this kit and only do it once and have everything work properly from the start. I wish I had.




by:

Perfect fit, easy to install, instructions were written very well with good pictures to aid in locations. High-quality material, should last for many years.

Highly recommended to replace those worn out corroded standard 4-pin trailer wiring harnesses.




by:
2004 Dodge Dakota

Bought 2 hitches. One went on with no problems. The other would not fit but discovered it had been slightly bent. Fit good when adjusted. Wiring harnesses were easy to install.




by:
2005 Dodge Dakota

I ordered a trailer wiring kit for my 2005 Dodge Dakota. Came nicely packed and well padded and therefore had no damage. The quality of the kit itself was top notch, looks pretty durable for a wiring kit. Also came with a dust cap and zip ties for installation. Its a pretty straight forward kit that fit perfectly. No need to "modify" anything. Every time I need something trailer related I always order from etrailer because I know I'll get exactly what I need and want. Thanks again!!!!




by:

My pickup didn't have the connection to hook up lights for a trailer. Our family is planning a hay-rack ride family event and I was chosen to tow the trailer. I looked in local places and the only one I found was at a dealer. They wanted over $100 for the wiring and $200 for the installation. They said it would take over 2 hours to install. I found this kit online and it took me less than half an hour to install it, even including cleaning off the mud on my existing connections! Very good product.




by:

Thank you for the help in getting the right part

Aloha
Living in hawaii it is sometimes
impossible to receive products ordered online in a timely manner. I was amazed to receive my order in less than 3 days. the trailer hitch was very easy to install as was the wiring harness and the whole project took less then 15 minutes.
thank you so much for a great product and even greater service

Appears to be good quality, hopefully it fits properly.

I could not be any happier with this product or with etrailer. This installation was very easy from beginning to finish. The price was very reasonable and I look forward to do business with etrailer in the near future.

  • Trouble Removing Taillights for # 55323 Harness Installation in 2011 Dodge Dakota 4x4
    I have linked you to a video showing installation of this Curt trailer wiring harness # 55323 on a 2006 Dakota. Although this vehicle is a few years older than yours the appearance of the taillight assemblies is quite similar to those on your 2011 Dakota and the process for their removal should also be. Often taillight assemblies will have additional plastic tabs to hold them in place (in addition to the screws) and these may require that you jiggle or rock the entire assembly to loosen...

  • Troubleshooting Curt 4-Pole Trailer Wiring Harness 55323 on 2005 Dodge Dakota
    I see that you purchased Curt 4-pole wiring harness # 55323 back in 2012. Since this is a passive harness that plugs in at your Dakota's tail lights the most-likely cause for your lighting issue is damaged or corroded connector contacts within the plugs. You can try a spray-on electrical contact cleaner such as Caig De-Oxit which can help remove corrosive build-up or if you prefer to can simply replace the harness. Sometimes even slight greenish or whitish discoloration of the contact...

  • Troubleshooting Curt Wiring Harness 55323 on 2004 Dodge Dakota
    The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 55323 likely has an issue at one of the connection points. I recommend using your circuit tester to make sure the function works correctly before connecting the harness at that connection location. If it works there, then I recommend cleaning the connections as best you can and using a little dielectric grease like # 11755. If the connections are good, and you have power at the point of connection for that...

  • How to Bypass 7-Way of 2007 Dodge Dakota to Fix Factory 7-Way
    Dodge trucks around the year your 2007 Dodge Dakota was made can be difficult when it comes to fixing trailer wiring issues. The TIPM which controls the trailer wiring is pretty easy to short out and only a dealer can fix it. The easiest way around it is to bypass it all together with a 4-way kit like the Curt # 55323 and then convert it to a 7-way with the part # 37185.

  • What Taillight Circuits Does Curt 4-Way 55323 Cover
    4-way trailer wiring connectors like what comes with the Curt kit part # 55323 that you referenced carry the taillight functions of running lights, brake lights, and turn signals but do not carry reverse light circuit. For that you'd have to convert the 4-way to a 5-way with the kit part # 20036. The extra wire of this would get tapped into the reverse light circuit of your vehicle and you'd have all the circuits covered.

    I reached out to my tech contact at Curt to get their thoughts.

Another vehicle connected to your trailer may be pulling more amps through the system which can allow a problem in even your trailer to be far less apparent. It is most likely a poor ground that is to blame for your dim lights. It can be a poor ground on the vehicle...
