Features:

  • Provides a 7-way, blade-style trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 4-pole, 5-pole and 6-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection point under vehicle
    • Plug in connector

Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located just beneath your vehicle, on the driver's side.


Once installation is complete, the 7-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 7-pole connector itself - to help prevent corrosion.

Great product and great price! No issues since installing on my 2022 Buick Enclave!



by:

Has worked fine for a year



by:
2019 Buick Enclave

This is a first-rate product. Very simple to install, since I already had the fascia off to install the hitch. My 2019 Buick Enclave already had the vehicle connector, so it was just a matter of locating the connector, removing the dummy plug and plugging in the trailer harness. I used this harness in conjunction with the Curt Trailer Hitch (Item CU29FR), the short no-drill mount (Item 18140) and the Pollak 7-pin mounting bracket (Item PK12711U).

My only complaint is that the harness is much longer than it needs to be, but too long is obviously better than too short.

2019 Chevrolet Traverse

I purchased a draw-tite hitch, wiring harness, motinting bracket and dielectric grease for my chevy traverse. I am very pleased with quality of these products and service. I do not usually take the time to write reviews, unless the company really impressed me. I am impressed how quickly they got this heavy package to me. They put together excellent installation videos on how to successfully install everything yourself. They delivered great customer service when I reached out to them on missing hardware for the wiring harness mounting bracket. They promptly send me the missing parts. I will come back to etrailer in my next hitch project.



by:

when I installed the 7 pin wiring harness , it stuck out too far for the hitch cover that attaches to the bumper. however I spun the bracket 180 so it was indented, thus allowing cover to fit. Maybe something to mention.Again overall, super happy with how fast the receiver was shipped. Looks great. While not been used yet, it was a great experience installing myself.



by:

This work great, fit perfectly matched with the dielectric grease made a great weather tight connection. I did have to reverse the bracket to allow it to fit with the bumper cover.
Wish I had ordered the grease and bracket at the same time as recommended, my mistake which delayed the installation.



by:

Easy to install. However, the 7 way plug and wiring harness did not fit as advertised. We had to rig it differently so that we could put the bumper cover back on. Instructions were clear and concise, just didn’t fit perfectly.



by:
2019 Chevrolet Traverse

We purchased a Draw-Tite hitch for a 2019 Traverse. Everything fit perfectly. I had a question about hooking up the 7 way plug cable and the support tech directed me to a video showing how to install the cable. Great service. Thank you!



by:

This wiring harness fit my 2020 Chevy Traverse LT, 3LT perfectly! I was able to get the the factory wiring harness without removing and of the panels, rear bumper, or rear facia. It was a quick plug and play installation. Just unhook the plug on the factory harness and insert this harness in its place. The factory harness is located right below the rear driver’s side taillight. I highly recommend this connector for it’s ease of use and the build quality!



by:

EASY INSTALL FOR HITCH, ALTHOUGH THE 7 WAY WIRING HARNESS 118287 DOES NOT ALLOW FOR THE CENTER PANEL TO GO BACK ON. BRACKET IS HOPKINS HM48625 AND IT SHOULD INCLUDE HARDWARE.



by:

The advice and help from etrailer is the reason I purchased everything I needed to install a hitch. I highly recommend etrailer



by:

Received this product and installed it. It is extremely easy to install as the harness plugs directly into the manufactures plug and works very well. I would definitely purchase another if the need arises.



by:

Wiring harness fit and easy to install



by:
2020 Chevrolet Traverse

The wires on the plug are so long and it was difficult to get it to stay in place in order to reinstall the bumper. I had to wrap it around the hitch and then fold the rest onto itself and zip tie it in place.

Don't bother wasting your time with this garbage!



by:

In my application I had to modify the mount to get the hitch cover to fit when not in use.



by:

Received my trailer wiring before expected. Ashley and E trailer have saved my holiday. Thank you



by:

Worked as advertised. eTrailer did a good instructional video on how to install on my vehicle that made installation easy. Thank you.



by:

Easy to install and works flawlessly!



by:

Perfect trailer hitch at a great price.



by:

Product was perfect, shipping was beyond slow, took almost a month to receive this item when it stated was in stock. That needs to improve at this point of having to wait we could have went to dealer to purchase.



by:

Easy install and works just fine. Come here for all of my trailering needs, which is often lol.



by:

Great product, online video made installation so much easier.

Fast, easy online order- timely delivery and good pricing.

  • Which is Better GM Tow Package or Curt Tow Package for 2019 Chevy Traverse
    I looked up what the GM trailer towing package includes for your 2019 Chevy Traverse and it gives you a hitch that installs through the rear bumper panel of the vehicle (just like our Curt part # CU29FR), and a 7-way trailer wiring connector just like our # 118287 at a much better price as I was able to compare the prices too! In my opinion it makes more sense to go with the towing products we offer as it's the (if not better), quality a much better price. I attached a picture of what...

  • Will the Curt Trailer Hitch Receiver # C13380 Fit a 2018 Chevrolet Traverse LT
    The Curt Trailer Hitch Receiver # C13380 that you referenced will fit all models of the 2018 Chevrolet Traverse including your LT. I confirmed this with my contact at Curt. This is a Class III hitch with a 2" receiver that has a 5,000 lb Gross Trailer Weight (GTW) rating and a 750 lb Tongue Weight (TW) rating. When use with a Weight Distribution (WD) system the GTW rating is raised to 7,500 lbs but the 750 lb TW remains the same. You will want to verify the weight ratings of your Traverse...

  • Trailer Brake Controller Options for a 2023 Chevy Traverse with Tow Package
    I do have some options for you but there isn't a plug under the dash for a trailer brake controller on a 2023 Chevrolet Traverse. Therefore, if you want to use a traditional dash mounted trailer brake controller you must hardwire which requires splicing into wires on the vehicle. However, if you go with a wireless trailer brake controller which is what I recommend, there is no splicing. I have attached options for both below. Wireless (Recommended): - T-One Vehicle Wiring Harness with...

  • Recommended Trailer Hitch Receiver Wiring and Brake Controller For Towing With a 2023 Chevy Traverse
    I recommend using the Draw-Tite Max-Frame Trailer Hitch Receiver # 76184 for your 2023 Chevrolet Traverse. This will place your receiver behind the factory receiver panel giving you a clean factory appearance when you are not towing. For the wiring I recommend installing the T-One Vehicle Wiring Harness # 118287 and replacing the included 7-way with the 7- and 4-Pole Trailer Connector Socket # HM40975. This connector will fit better behind the cover and has both a 4-way flat and 7-way blade...

  • I Need Both The 4 Flat And 7 Way Trailer Wiring Connectors For My 2022 Chevy Traverse
    You are correct in that the Hopkins # HM40975 will not come with any wiring as it is intended as a factory replacement for an existing damaged one, and that the Tekonsha # 118287 will only have the 7 Way connection and not the 4 Flat. With that said, you will have two options. First is to go with the Tekonsha # 118287 and use a 7 to 4 adapter, like the Pollak # PK12716. Personally, I am not preferable to these as I am prone to misplacing and/or losing things. They do work perfectly fine...

    To convert the 4-way connector on your 1996 Chevrolet C3500 to a 7-way you will need is the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires item # ETBC7. The kit includes a pre-wired 7- and 4-way trailer connector that mounts easily at the rear of your vehicle with an included bracket.

  • Recommended Trailer Hitch Receiver and 7-Way Wiring Harness For a 2023 Chevrolet Traverse
    I recommend using the Draw-Tite Max-Frame Trailer Hitch Receiver # 76184 on your 2023 Chevrolet Traverse. This receiver is designed to install behind your rear fascia and is accessible by the removable panel on the rear fascia. It has a welded tab which will allow you to install a Mounting Bracket # PK12711U to attach a 7-way connector. The T-One Vehicle Wiring Harness # 118287 will allow you to add a 7-way connector to your Traverse. An Adapter # 78118 can be used when towing smaller...

  • Recommended Trailer Hitch Receiver For A 2021 Chevy Traverse
    For a 2021 Chevy Traverse we have two trailer hitch receivers, the etrailer Trailer Hitch Receiver # e56YR and the Curt Trailer Hitch Receiver # CU29FR. Both have the same maximum gross trailer weight capacity of 5,000lbs and maximum tongue weight capacity of 750lbs and are rated for use with a weight distribution hitch. They both are both bolt-on installations and the Curt hitch has a black powder coat and the etrailer has a matte black finish, for superior rust protection. Both of these...

  • Comparing Different Trailer Hitch Options for a 2020 Chevrolet Traverse
    There are two main trailer hitch options for a 2020 Chevrolet Traverse, the Draw-Tite Max-Frame Trailer Hitch Receiver part # 76184 (see photo one) and the Curt Trailer Hitch Receiver part # C13380 (see photo two). The main difference between the two is that Draw-Tite hitch installs behind the rear bumper so it will be more difficult to install but then again it will also provide a much cleaner look once installed. On the other hand, the Curt hitch will be much easier to install but it...

    For your 2018 Chevy Traverse I recommend the Tekonsha T-One Vehicle Wiring Harness # 118287 if you need a 7-Way connector or the Tekonsha # 118761 if you need a 4-Way connector. These are both custom harnesses that will install by simply plugging into a factory port beneath the vehicle on the driver's side (see attached image). I recommend these over the Curt options that are also available for your Traverse because of Tekonsha's reputation for producing extremely reliable products. We...

  • Installation of P2 Brake Controller in 2022 Chevy Traverse With Factory Tow Package
    We can help get the Tekonsha Prodigy P2 Trailer Brake Controller, # 90885 connected to your 2022 Chevrolet Traverse. But there is not a simple plug-in wiring adapter such as the # 3026-P available.

For your 2019 Chevy Traverse LT, you will want the Curt Trailer Hitch Receiver - 2" # CU29FR which is a fit for 2018 to present models. You will be able to install the cover over the hitch when not in use for that clean look. I've attached a video to assist.

  • Is Curt Trailer Hitch # CU29FR a Good Fit for a 2018 Chevy Traverse
    There actually isn't a problem with the hitch, # CU29FR, for the 2018 Chevy Traverse. We have had so many more people have no problems at all than those that did so I think I can explain what happened in those 2 issues. While I can't say why the one customer had such a hard time removing the fascia but as far as the alignment issue that was mentioned there is a simple explanation. Basically, hitches can flex. And when they get tossed around in the shipping process it can cause the holes...

  • Recommended Trailer Wiring For A 2020 Buick Enclave
    If you need the 4 pole connector on your trailer, I would recommend the Tekonsha T-One Connector # 118761 over the Curt # C56394. It provides more length for your installation, heavier duty wiring, with a more robust dust cap construction. The mounting bracket # 18144 for installing the connector as well as dielectric grease # 11755 to keep out corrosion and dirt would wrap up this package. If you instead have a 7 pole connector on your trailer, I recommend the Curt T-Connector # C56393...

    The Curt Trailer Hitch Receiver C13380 was discontinued back in 2020 which is why you aren't able to purchase it. This was replaced with the Curt Trailer Hitch # CU29FR for your 2020 Chevy Traverse which has a better design since the crosstube is hidden. With the crosstube being hidden it gives you better ground clearance plus it looks more clean and it can be completely hidden when you put the bumper cover back in place.

This hitch hides behind the access panel of your rear fascia just like the OEM hitch does and has plenty of towing capacities. I attached an install video for you to check out too.
