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



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.



by:
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:

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:

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:
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.

Wiring harness fit and easy to install

Perfect trailer hitch at a great price.

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

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • How To Use Tekonsha Primus IQ Trailer Brake Controller On a 2020 Chevrolet Traverse
    The Tekonsha Primus IQ Trailer Brake Controller part # TK90160 is a great option for a 2020 Chevrolet Traverse and it will offer plug-n-play installation when used with the Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers part # 3026-P. If you don't already have a 7-way, the T-One Vehicle Wiring Harness with 7-Way Trailer Connector part # 118287 is also a plug-n-play fit.

    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.

  • 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...

It has a maximum gross trailer weight capacity of 5,000lbs and maximum tongue weight capacity of 750lbs (note: this will increase the towing capacity or tongue weight of your vehicle so you'll need to refer to your owner's manual and follow whichever rating is lower).

  • 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...

    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...

The T-One includes a ModuLite power converter to ensure that your vehicle's wiring matches that of your trailer. With the T-One, you will have full functionality of brake lights and running lights on your vehicle.

    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.

  • Installing Trailer Brake Controller on 2018 Chevy Traverse
    Based on my research it does look like the 2018 Chevy Traverse is equipped with blunt cut wires beneath the dash for installing a trailer brake controller as part of its standard package. To be certain of this you can visit a local Chevy dealer with your VIN and they will be able to tell you exactly what the vehicle was equipped with at the factory or you can simply check the appropriate location inside the Traverse to see if the wiring is present. On the 2018 Traverse the blunt cut wires...

These wires will directly connect with the wires of the pigtail included with your brake controller. The wire bundle should be taped to a larger wiring harness, and will usually have a white tag or label on it. The 4 wires will connect as follows: The blue tow package wire connects to...

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.
