Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector

As with all tasks around my house, I have to do things myself. Installing this 13424 receiver hitch on a 2015 Chevy Traverse LTZ was no exception. The biggest challenge was loosening the dual muffler rubber hangers, 2 per side. The other issue was how to hold this 25-50lb receiver hitch with one hand while screwing in the bolts. By creating a third hand, the whole process took me about an hour. Fit beautifully, well made and solid. Fun part - the carriage bolt fish wires. Just need to have the wiring harness installed by a professional. Did that myself on an old vehicle and some years later sent my dashboard lights into a tizzy because the device got wet and shorted. I would buy a CURT product again. 228646

I bought this wiring harness after watching the installation video on the Etrailer website. I installed this in my driveway with the use of my floor jack. It took about an hour for me to install it. It was easy to install and it worked without flaw the first time. Great product! Great company! Thanks! 325006

The trailer hitch was fairly easy for my husband to install on my Chevy Treverse and has served its purpose well. We have a 6ft trailer we hook to the back for hauling firewood and items for projects. We have been very happy with the quality, prices and delivery time of all the products we have ordered from etrailer. 640230

Easy plug and play harness! Recommend using more weather proof connectors though. Great installation video to ease installation! When installing this will need mechanics wire to help "fish" wiring through rear bumper support as described in video. 614093

I ended up cutting thru to tail lights with a hole saw to get the connectors thru into the tail light recesses they fill the hole with shoe goo to seal. It really worked better than it sounds. My LTZ has rear heat/AC on on one side and power hatch lift on the other so the connectors for hitch wiring were not accessable. i did connect into the rear power plug for 12V power for the relay so I didnt have to run all the way to the battery. 610492

A powered taillight converter should draw its power from a direct connection to the vehicle battery, but will gain its switching information via its connection to the vehicles taillight harness or tow package connector. Years ago, taillight circuits in vehicles used higher gauge wire and had enough capacity to handle the draw of the vehicle taillights as well as those of a trailer. Now that the price of copper has gone through the roof and vehicle manufacturers try to save all the weight and expense they can, the taillight circuits use smaller gauge wire that can handle the load from the vehicle taillights but not much else. Drawing the power directly from the battery also serves to isolate the tow vehicles sensitive electronics from any short circuits that might occur in the trailer wiring. Connecting the converters power feed anywhere other than the battery or where the converters manufacturer recommends can leave your vehicles electrical system exposed to possible damage.

Installed at night without a ton of light and still went on a 2014 traverse pretty easily. It's been over a year with northern illinois weather and no problems. 607756

Exactly as pictured and what I ordered. Arrived early very satisfied. 599306

I started with a "this will work kit" from my local parts store...turns out it was only for a Traverse that comes with towing package, which I do not have...out $40. Next I stumble across this harness from etrailer... exactly what I needed! Quick shipping and super great instructions with photos specific to install to my traverse...all the way down to which screws to turn. Plugs into the taillights plus a hot wire from the battery. 599059

Curt makes great trailering products and etrailer.com makes customer service a breeze. Installation was simple and took less time than I guessed. The available installation video was spot on for how to get the job done. Well done to etrailer. 578645

Easy install 2013 LS FWD. I had no issues after following the video. The only thing they did not show was having to unbolt part of the battery box heat shield to gain access to the battery vent. I went the extra mile by installing 1/4 harness wrap on the green wire through the bumper rail and the positive all the way to the battery box. There are some sharp edges under the body that could cause a short over time with no protection. I also purchased the 4 plug tester. All is good. 562358

These guys are really good. 540350

The functionality of this unit is great! The installation video and instructions are lacking. Several direction steps were not hard they simply were impossible. If the part about most vehicles have the trailer wiring tucked up the side would have been great to know before we purchased. Also a description of what to look for would have been a help also. 523985

The wiring harness itself it really great. My vehicle did not have a factory trailer wiring harness. This one did take about 4 hours to install. I have no lift, so I used my jack to lift the right rear off the ground to crawl under the car to run the power wire to the battery. My vehicle also has the rear AC and ventilation controls which makes the right rear side too difficult to access the wiring grommet, so I routed all the wires out the left side and spliced the right directional wire (green) going to the right side to gain the extra length I needed. Beyond that I would suggest using some plastic spiral insulation around the wires to protect them against sharp edges of the metal body. 518065

After I removed the crap that the trailer rental place installed, my trailer lights worked perfectly. Took me about 30 minutes to install. 515589

Easy install, however my first wire harness the control box stopped working after 2 months of use. Just installed my new harness. too early to tell if this will fail as well. 515100

The most common reason a converter box fails is a short circuit in the trailer wiring. Youll want to closely examine the wiring on your trailer, beginning at the trailer connector and working backwards tracing each circuit until you reach each lamp. Look for loose connections or pinched wires. Closely examine the plastic insulation on the wire, looking for cracked or worn insulation that would allow the copper wire to short out on the trailer frame. If there is a short somewhere in the trailer wiring, youll continue to fry converter boxes until the short is located and repaired. Ill link you to a help article that contains lots of good information about troubleshooting trailer wiring systems.

Troubleshooting 4 and 5-Way Wiring Installations

Takes a little time to install, but works great. Online installation videos are very helpful, easy to do. 484426

Super videos on etrailer's YT page. Product installed very easy. 479381

A perfect fit for my 2013 Traverse. No modifications were necessary. Thanks again to CrystalS for all her help. Give that girl a raise. 471834

2017 Chevrolet Traverse

I bought a trailer hitch for my Chevy Traverse and it went on easily and works well, however the trailer light package burned out in November 2017. It blew fuses and I could smell hot plastic. I did not find any shorts in the wires, it may have been the plastic "black box" part of the wiring harness. I have since replaced it with the type of harness that plugs into the plug by the left rear fender. I also purchased that from etrailer. Hope it works. 464978

The majority of the time when a converter box shorts out, the cause is a short circuit somewhere in the wiring on the trailer. Begin by checking the trailer connector, look for damage or corrosion. Trace each circuit rearward looking for pinched or broken wires. Check that all connections are secure and protected from the weather. Carefully examine the wire insulation, look for worn or cracked spots that would allow the copper wire to contact the trailer frame or other metal and cause a short. Youll want to located and repair the short before replacing the taillight converter, or youll continue to blow out converter boxes.

Vary good product. I wish I would have seen the factory connection on the vehicle first. Watch all the videos etrailer puts up on their page first. My fault. 432940

Installation not too difficult and it works great! 409714

The wireing harness was super simple to install. The online video gave me the confidence I needed! 399167

The sales person was helpful. The product works great. 387282

Everything fit as expected. 379164

Still working fine.

Tom H - 05/11/2018

The curt wiring harness lasted one year then the left side shorted out and blew the fuse for my left running lights on the car.had to buy another one.i hope it lasts longer or i will have to go another way. 375009

order and deliver items in 3 days as promised. Great service 363370

I am 82 years old, it took me a little longer to get it done but went in an tested fine. The hardest was to get the wire into the battery box. 360566

THE HITCH WAS VERY TO INSTALL TOOK MAYBE 15 MINUTES THE WIRING ON THE OTHER HAND WAS NOT TOOK IT OUT OF THE BOX AND TRIED TO FOLLOW THE INSTRUCTIONS IT WOULD HAVE TAKEN QUITE SOME TIME TO INSTALL. SO I GOT A HARNESS FROM THE GM DEALER AND IT TOOK 5 MINUTES TO INSTALL. SO NOW I HAVE A HARNESS I CAN NOT USE. THE HARNESS THAT WAS SENT I WOULD HAVE TO TIE RIGHT AND LEFT SIDE TOGETHER GLUE SOME MODULE TO PANEL AND THEN RUN A WIRE UNDER THE CAR ALL THE WAY TO THE ENGINE COMPARTMENT. THE HARNESS FROM THE GM DEALER WSA PLUG AND PLAY . LIKE I SAID IT TOOK MAYBE 5 MINUTES 355628

Super fast delivery, and excellent quality. Customer service cannot be any better. Could not ask for more from a business. 335565

Installed easy as pie and as usual etrailer is an amazing site. Easy to find things and, support is great, and staff is super helpful and friendly. I won't go anywhere else for my towing accessory. needs 334760

2016 Chevrolet Traverse

Fit perfectly. Well within manufacturing specs. No challenge by the Chevy Dealer garage on installation and since this is a plug in/bolt on with no cutting no warranty is broken. 320130

2014 Chevrolet Traverse

We installed a tow package on our 2001 Jeep and our 2014 Chevy Traverse. Both were easy to install and have worked flawlessly as advertised. I personally would purchase from E-trailer again. 314349

Product arrived as promised. Perfect transaction and GREAT communication with fast, easy delivery. Will continue to buy from in the future!!! 289513

Seeing as I leaped (and ordered) before I looked, my new Traverse was equipped with a hitch. etrailer's customer service rep Lisa guided me through the process of making a return. She was so very helpful. I give etrailer a 5 star rating, because this is my third order from them and they always supply the best products, at best prices, and now I applaud there customer service. I will return again when ever a need arises. They are the first I turn to. 284318

I bought the draw tite trailer hitch and the t connector 4 way flat wiring harness for our 2014 traverse. It was very simple and easy to install. No issues as of now and I will be using it to tow our camper in a few days. 281066

Great product, installation was a breeze. I changed a few things like running the green passenger side wire through the rear bumper tube and instead of running a wire all the way to the battery I was able to splice into the power going to the rear power outlet. This outlet has 20 amp fuse feeding it under the hood so the 10 amps needed for the trailer wiring should never be a problem. Use only a few tools to install(knife, wire stripper/cutter, small screw driver, and a nut driver). Very high quality kit with online videos to walk you through the process. Took me an hour to install on my garage floor. 273965

2015 Chevrolet Traverse

Exactly what I wanted, but some of the wires were short. I had to splice in extensions. 266044

Everything I needed was provided in the wiring kit. Installation instructions were easy to follow. The only thing I found in error was the location of the battery which was shown to be under the hood, it is located in the floor behind the passenger seat. 255813

2013 Chevrolet Traverse

This hitch system was so spot on to install easily onto my 2013 Chevy Traverse. I did most of it by myself. The holes all lined up perfectly. The only worry I have is with the very basic brake wire that runs under the chassis to the front end. We get a lot of extreme weather elements in Minnesota and chemical spray from the roads. It maybe could have been offered with a protective sleeve. 244029

thank you 238123

Web site works well. You tube videos are great for installation instructions. Thanks, Glen 230428

Good prices, quick delivery 218336

Very easy to install in less than 20 mi nutes 199990

I am very pleased and is why I continue to come back to your company and refer as much as possible..

Bill C - 06/17/2016

I bought products:C56181,TM75127, D13035, D/3503, 39523, PS49903, ETBC7, from E Trailer, and installed them on my wife's 2015 Chevy Traverse. Over all the products were pretty easy to install, but it still took a while to do it right. When installing the Brake controller, and connecting to the brake petal switch connect to the white wire in plug taped back on the left side under drivers side dash, and do so on the plug prong, with a female spade crimp terminal, not the inline crimp connector provided, they aren't very reliable I my experiences. Also soder all your but joints and heat shrink, or tape, I've had too many problems with crimp terminals corroding. On the Transmission cooler get some very light gauge 1 1/2 x3" angle iron and mount your cooler to it on the 3" side suspending down from at least 3 front grill torx headed screw ran through the 1 1/2 side of angle, I didn't like the idea of shoving the chess plastic mounting kit through my radiator, plus it eliminates the need of removing electric fans and this way you only hafta take top screws out of front grill and slide cooler and bracket down through. Thanks E trailer for compiling all videos these were very helpful? 194226

Everything as expected. Good directions specific to my vehicle. It took me 3 hours to install which was longer than I expected, but fun DIY project. 186887

Almost easy to install. Pictures and instructions were easy to follow except when running wire to right hand light assembly. Directions tell you to do the same as left side but I was unable to because of the blower unit. Ended up running wire out the same hole as the right side and under truck to other light assembly. Also would have been nice to know that the battery wasn't in the engine compartment (on me not manufacturer). Once in worked great. Took me about 1.5hrs to install. 186226
