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

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.

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! 830693

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. 795998

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! 713703

Ask the Experts about this Tekonsha Custom Fit Vehicle Wiring

  • Recommended 7-Way Wiring For 2020 Buick Enclave
    I recommend the Tekonsha T-One Vehicle Wiring Harness with 7-Way Trailer Connector part # 118287 which will plug into the OEM harness on the driver's side frame rail and give you a 7-way plug on the back of the Enclave. I have attached a video on a 2019 Chevy Traverse but it will be the same on your Enclave. To mount the plug I recommend No-Drill Mount for Electrical Mounting Bracket - Short part # 18140 with Mounting Bracket and Installation Hardware part # PK12711U.

  • Can Rear Hitch Access Panel Cover Reinstall on 2020 Buick Enclave with Tekonsha 7-Way Installed
    The 7-way kit part # 118287 will fit behind the rear hitch access panel of your 2020 Buick Enclave. You might have to bend the bracket back a little bit so that the cover fits over it but that wouldn't be an issue at all.

  • Recommended Trailer Wiring Harness for 2018 Chevy Traverse
    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....

    There are no relays or fuses required to install the T-One Vehicle Wiring Harness with 7-Way Trailer Connector # 118287 on your 2018 Chevy Traverse. It will simply plug into a harness under your vehicle and that's all there is to it. I have added a link to the instructions as well as a video installation for you to check out of the T-One Vehicle Wiring Harness # 118287.

  • Aftermarket Tow Package Recommendation for 2020 Chevy Traverse Instead of OEM GM Package
    We have an OEM style of hitch solution for your 2020 Chevy Traverse that is going to cost much less than a dealer option and will be just as strong with the Draw Tite hitch part # 76184. This hitch hides behind the access panel of your rear fascia just like the OEM hitch does and has plenty of towing capacities. See picture. I also attached an install video for you to check out too. For trailer wiring then you'd want the OEM style 7-way part # 118287 which easily installs by simply...

  • Which is Better GM Tow Package or Draw Tite 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 Draw Tite part # 76184), 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...

  • Can the Access Panel Be Re-Installed On a 2019 Chevrolet Traverse with Draw-Tite Hitch 76184
    Yes, the rear access panel on a 2019 Chevrolet Traverse can be reattached after the Draw-Tite Max-Frame Trailer Hitch Receiver part # 76184 is installed. Therefore, there will be no signs a hitch is present with this cover installed as no other part of it is visible from the rear of the vehicle. The Draw-Tite Max-Frame Trailer Hitch Receiver is a great option to as it does not require any cutting or drilling for installation. I have personally installed this trailer hitch myself and can...

  • Is Factory or Aftermarket Tow Package Better for 2020 Chevy Traverse
    I highly recommend using the Draw-Tite Max-Frame Trailer Hitch # 76184 and either the 4-Way T-One # 118761 with mounting bracket # 18144 or the 7-Way T-One # 118287 with mounting bracket # PK12711U over the GM tow package for your 2020 Chevy Traverse. Sometimes the factory tow package will include specific things like an additional transmission cooler but from what I could find GM doesn't say that the towing weight ratings for your Traverse are dependent upon their tow package or not.

    The Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C13380 sits underneath the factory bumper cover. I've attached a photo to assist.

If you need the wiring, I recommend the T-One Vehicle Wiring Harness with 7-Way Trailer Connector # 118287 and mounting bracket # PK12711U. For...

  • OEM Versus Aftermarket Trailer Hitch and Trailer Wiring Harness for 2020 Chevy Traverse
    Honestly speaking, the primary difference is the mark-up the car stealership charges you. A few years back the OEM hitches did have an aesthetic advantage for many vehicles, such as the Traverse. The OEM hitches installed behind the bumper, and were partially or fully concealed. Many folks didn't like the appearance of a big hunk of metal (the hitch) hanging below the rear bumper, so they accepted the extra cost of the OEM offering and went on about their business. These days it's...

  • Trailer Wiring for 2020 Chevy Traverse with 7 and 4 Pole Connectors
    I do have a way for you to have a 7-way and 4-Pole connector on your 2020 Chevrolet Traverse, but there isn't a wiring harness for your car that comes with both plugs. You can use the T-One Vehicle Wiring Harness # 118287, which is confirmed to fit your Traverse, and plugs directly into your factory harness. You can then use the Hopkins # HM40975 in place of the 7-way socket that comes with the harness. The # HM40975 also comes with a mounting bracket to easily attach it.

  • Best Trailer Hitch and Wiring Harness For 2020 Chevy Traverse Towing A Utility Trailer
    I recommend the Draw-Tite Class III Max Frame Receiver Hitch part # 76184 for the 2020 Chevrolet Traverse because of it's concealed cross tube design it provides the best ground clearance compared to the other options. The concealed cross tube design sits up higher since the receiver tube sticks out fascia instead of hanging below the bumper. The receiver tube will be the only portion of the hitch vehicle once it's installed. This hitch also allows you to re-install the panel that hides...

    You can easily add a 7-way to your 2019 Buick Enclave. The only thing you need is the T-One Vehicle Wiring Harness with 7-Way Trailer Connector # 118287. To install this you simply need to plug this into the factory harness, which is on the driver's side stashed under the vehicle, as you can see in the cut out of the linked installation instructions I added for you. I also added a link to a video review of this harness for you to take a look at.

  • Parts Needed to Add 7-Way Trailer Wiring Harness to 2019 Chevy Traverse
    If you wanted to install a 7-way on your 2019 Chevy Traverse without current trailer wiring all you need is the T-One 7-way kit part # 118287 and you'd be set. This plugs right into the trailer wiring port at the rear of your vehicle and will give you a fully functional 7-way. I attached an install video link for this kit for you to check out as well.

  • 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...

  • Is Draw-Tite Trailer Hitch # 76184 a Good Fit for a 2018 Chevy Traverse
    There actually isn't a problem with the hitch, # 76184, for the 2018 Chevy Traverse. We have had twice as many 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...

  • Comparing the GM Tow Package and Aftermarket Tow Package for a 2020 Chevy Traverse
    The factory towing package on a 2020 Chevy Traverse consists of a trailer hitch and trailer wiring harness which we have options for on this vehicle. The main difference between the factory and aftermarket components is mainly cost therefore aftermarket is what I recommend as it will be most effective. For a trailer hitch, I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver part # 76184 which installs just as the factory hitch would with no drilling or cutting required. The best...

  • Recommended Plug and Play Brake Controller for a 2018 Chevrolet Traverse
    Yes, you will need to install a brake controller on your 2018 Chevrolet Traverse in order to activate electric brakes on a trailer. For a plug and play option, there are few better than the Curt Echo Mobile Trailer Brake Controller part # C51180. The reason for this is because it uses a device most individuals are familiar with, their phone which also means you don't have to read a comprehensive manual and learn all the codes. If your phone dies while using the brake controller, the device...

    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...

    I really like the Draw-Tite Max-Frame Trailer Hitch Receiver # 76184 for your 2020 Chevy Traverse because it not only has a sleek, OEM look (you can actually replace the cover), but it also has a wiring mounting bracket integrated in so if you were to install some wiring like the 4-Way # 118761 or 7-Way # 118287 then you'd have a convenient spot to attach it using a mounting bracket like part # 18144 or # HM48625.

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...

    We have two options for trailer wiring for your 2018 Chevy Traverse. We have the 7-way kit part # 118287 and the 4-way part # 118761. Basically it comes down to what type of connector your trailer has for you to know which you'd need. If your trailer has a round plug for trailer wiring you'd want the part # 118287 or if instead it has a flat connector with 4 wires ran to it you'd want the 4-way part # 118761.

There is not a built-in brake controller port on your 2018 Buick Enclave that will allow for installation with a Plug-In Adapter, however all the needed wires should already be run under the dash.

For that you'd want the T-One kit part # 118761 for a 4-way or part # 118287 for a 7-way. If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900.

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...
