CURT Custom Fit Vehicle Wiring

  • 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 rear bumper
    • 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 rear bumper, on the driver's and passenger's sides. You will have to remove the protective plastic covers on either side of the bumper to access the connection points.


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.

Thank you for your feedback. You certainly can add wire loom like part # 459075-1
Wire Loom, 1/2" Diameter (per Foot)

to help extend the life of your harness.

Great product, well made. Installed on 06' Jeep Unilimited. Connectors and wiring harness are quality and overall install was easier than expected.




by:

Excellent product. Had to replace an older harness that had been installed incorrectly. etrailer’s Curt T-harness was on the money for my 2005 Jeep Wrangler Unlimited. Their install videos were very good, and Steven B. was super helpful with my order. Super fast shipping was a plus also.




by:
2005 Jeep Wrangler

The Curt T- Connector was exactly what was advertised. Free delivery was quicker than expected (three days). After watching the YouTube install video it was smooth sailing and was installed in about an hour and a half with assistance from my wife. (this time I know I was the assistant).




by:
2005 Jeep Wrangler

High quality and simple install with video. There will only be about 3 ft of pigtail going toward the front bumper (if you are wiring for flat tow) so get the tow bar wire kit too.




by:
2002 Jeep Wrangler

My order of a trailer hitch, light kit and mounting bracket all arrived very quickly, even before I expected them. The product quality is great. The installation instructions were very clear and easily followed and I had no problem at all during the installation process (probably because I for once took the time to read the directions first). As in the past, etrailer has exceded my expectations.

After one year and quite a bit of use the wiring kit is without problems. Id do it all again,

I installed this connector on my 2006 Wrangler with a Hidden Hitch and it has worked flawlessly with three different trailers. Very happy with etrailer and this harness. Thanks,

Everything is working fine and I appreciate the helpful videos and instructions provided on your site.

A very nice product. The installation was a quick, plug & play process. Everything went very smoothly - Zero surprises!
Since I'm a bit OCD. I purchased a roll of 3/8" split wire loom along with a package of small zip ties from a local auto parts retailer. I then placed the wiring harnes into the loom. Using the additional zip ties about 2' apart.
Then, I ran my my wires under the rear bumper,between the body & frame area.
Today, over a year later - Everything works as it should.
Cheers.

Bought the Curt hitch and wiring kit for 2013 Highlander and was entirely pleased with product, installation instructions, and performance for a couple years. Recently traded the 2013 for a 2019 Highlander and have bought the same hitch and wiring kit for it. 100% positive recommendation for etrailer, their products and customer service.

I ordered the Curt trailer hitch, wiring harness, and ball mount for my jeep. All products are high quality, should last a lifetime. The price is very reasonable and the videos make installation possible by even a not so mechanical minded person. The products are shipped in quality boxes and packed should withstand even rough handling. The shipping was really fast as well. The reps also follow thru with shipping information easy for you to track entire route of the products. I am a very happy camper, comfortable with this company selling quality products for reasonable prices. i will order again, Try them, you will like them too!

2002 Jeep Wrangler

This was my third purchase from etrailer and every experience has been AWESOME. When searching the wiring harnesses I needed, I first watched the installation video to make certain it would fit my Jeep. All three orders were delivered very quickly, and was super easy to install. Thank you etrailer for teaching me how to wire a trailer through your videos and making the purchase so convenient.




by:
2015 Jeep Wrangler

this is one of the BEST products I have bought in a long time that fits PERFECT, It took me literally 15 minutes to put this trailer hitch on my wrangler , and another 15 to install wiring kit . this was on my TJ and I put one on my YJ I also bought from Etrailer.You Guys are GREAT, keep doing your great work. Thanks so much, Sincerely Jack G.

2000 Jeep Wrangler

The Curt hitch and wiring kit arrived in perfect shape I installed the hitch and wiring harness in less than two hours. Tested the lights=perfect. The fit and looks=perfect. I enjoyed doing business with etrailer and am looking forward to buying more products. What a great company!




by:
2006 Jeep Wrangler

Be forewarned this is not a pure "snap-in" harness. The ground wire does not connect to the vehicle harness, instead it comes with a self-tapping screw and instructions to drill a ground point into the vehicle. I was able to ground to a nearby bolt on my '06 Wrangler by cutting the ring connector to accommodate a larger bolt. This worked fine and avoided the need to drill. Also, the zip ties it comes with are too small and too few for the job, so have a bag of 8" ties on hand. Otherwise it works great, the install into the harness was easy and no problems with the first tow.




by:
2004 Jeep TJ

The hitch and wiring were a breeze to install on a 2004 Jeep TJ. I'm a friend of the purchaser and have installed at least a dozen hitches from etrailer for friends and family, including this one. etrailer has great pricing, fast delivery, and the installation videos are very helpful. I know exactly what to expect before the hitch arrives. If you're on the fence, watch the installation video before you buy. Good luck!

This was my 1-st purchase from etrailer.com
The
wiring harness installed perfectly. I found the quality to be exceptional. Will definitely buy from etrailer.com in the future




by:

Katie D, The wiring harness works as advertised. Simply unplug the connectors and plug the new ones inline. Thank you so much for making a job much easier!




by:
2006 Jeep Wrangler

We ordered a hitch and wiring harness for a 2002 Jeep Wrangler and a wiring harness for a 2006 Jeep Liberty. We received them incredibly quickly and, thanks to the excellent installation videos, installed them all this morning in just an hour or so. This is our third purchase from etrailer.com and we would definitely order from them again.




by:
2006 Jeep Wrangler

Ridiculously easy installation, no splicing! Only issue is that the supplied plastic wire ties were not long enough, I had to get my own to secure the wiring to the trailer hitch frame.




by:

I was able to use the Jeep trailer wiring adapter to run a male/female inline 4 plug to the front of my Jeep for towing behind my RV.




by:


Online purchase process was easy and
quick. I was a little concerned about the harness possibly needing "modification" as has been my experience in the past ordering from other retailers. To my delight no modification was required. It went together just as your description said it would and I was was done in a matter of minutes. Thanks again

2003 Jeep Wrangler

Perfect! Easy online ordering, quick delivery, great price and easy to find tutorials on YouTube. Thank you. I highly recommend eTrailer.

  • Troubleshooting Short on 2017 Hyundai Santa Fe with Curt Trailer Wiring Installed
    The Curt harness part # C55363 is probably not the real reason your lights shorted out, but it probably helped it happen. What would have had to happen was that your trailer's wiring put a short on the circuits of the Curt harness which then transferred to the vehicle and caused the light to stop working. The harness is just wires without any type of circuit board so it should still be fine unless there's melted or exposed wire on it. Which that would indicate a massive short on your trailer's...

  • Curt 4-Pole Wiring Harness C55363 Installation in 1999 Jeep Wrangler
    Curt 4-pole wiring harness # C55363 is a correct fit for your 1999 Jeep Wrangler. If you find that the turn signals are reversed for left and right this just means you need to switch the plug-in connectors to the opposite sides of the vehicle. The connectors with the yellow wire should plug in at the left/driver side tail light; the connector with the green wire should connect on the right/passenger side light. For reference I linked an installation video showing a 2004 Wrangler.

  • USA Made Trailer Wiring Harness Recommendation for 2003 Jeep Wrangler
    I wish I could say yes to that but no they are not. For a made in the USA trailer wiring harness confirmed as a fit for your 2003 Jeep Wrangler we have the Curt kit part # C55363 which would work great. I attached an install video as well.

  • Wiring Fit and Compatibility on a 2006 Jeep Wrangler-X
    If you don't have a factory 7-way already on your vehicle the Hopkins wiring harness # 32625, the Tow Ready # 118409, or the Curt # C55363 will fit for your 2006 Jeep Wrangler-X. I recommend the Tow Ready # 118409, because it is the most popular among our customers. I have linked all the wiring harnesses that fit a 2006 Jeep Wranger-X without the factory tow package for your vehicle for your convenience.

  • Parts Needed to Install 7-Way on 2005 Jeep Wrangler
    Not all of the 2005 Jeep Wrangler came with the wiring needed for the # HM40975-11933 to attach to. If you can't find the necessary connection it's very likely you don't have it and you'd need to instead install a 4-way with part # C55363 and then convert it to a 7-way with the part # 37185.

  • Hitch & Ball Mount for 2002 Jeep Wrangler to Clear Spare Tire
    You can avoid clearance issues between your 2002 Jeep Wrangler's rear-mounted spare tire and your towing ball mount by using a ball mount long enough that will extend past the rear edge of the tire. The 2-inch hitch I suggest for your 2002 Jeep Wrangler Unlimited is Curt # 13408. This is a no-drill bolt-on installation. When we installed a Class III hitch on your vehicle we found that the distance from the hitch pin hole to the rear of the spare tire was 6-1/4-inches. Once it is installed...
