  • Tekonsha

Quickly and easily install a 7-way, RV-style trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring - no cutting, splicing or tapping required.


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
  • Constructed of 16-gauge bonded wire

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.

The trailer hitch was ripped through the shipping box. Please look at pictures to see if all parts are there . Just need confirmation so when I install everything is good to go.

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.

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:

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

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:

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:
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:

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.

  • Is Factory or Aftermarket Tow Package Better for 2020 Chevy Traverse
    I highly recommend using the Curt Trailer Hitch # CU29FR 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. With this being...

  • Are Fuses or Relays Needed to Install T-One 7-Way Connector on 2018 Chevy Traverse
    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. To complete the towing setup on your 2018 Chevrolet Traverse I recommend the Curt Trailer Hitch Receiver # CU29FR...

  • Does 7-Way Sit Behind Fascia With Hitch on 2020 Chevy Traverse With Tow Package
    The Curt Trailer Hitch Receiver # CU29FR for your 2020 Chevy Traverse is recessed pretty far back, so you should not have any issues replacing the fascia after installing the T-One Vehicle Wiring Harness with 7-Way Trailer Connector # 118287. I do recommend going with the shorter bracket for this, the No-Drill Mount for Electrical Mounting Bracket - Short # 18140 with the 7-Way Mounting Bracket # PK12711U. When plugging the 7-way into the factory socket of your Traverse, you will want...

This is a matte black finished Class III hitch with a spec rating of 5,000 lbs. for max GTW and 750 lbs. tongue weight, but always refer to your vehicle specific owners manual for the vehicles max specs for towing. It is a custom fit bolt-on model that comes with all needed hardware and lifetime technical support from the experts at etrailer. Made in USA. You will need a ball mount, such as...

  • 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.

  • How to Add a 7-way and 4-flat Wiring Harness to a 2000 Chevy Silverado
    Since your 2000 Chevy Silverado has the factory wiring harness, you will need the Reese Multi-Plug Wiring Harness for Factory Tow Package item # 74682. This harness will plug directly into that OEM port and give you both a 7-way and 4-flat connector. I have linked an installation video below. You will want to confirm that your truck has the same connector as the one in the video. If you do not have this OEM port than you will need two separate parts to give you a 7-way and 4-flat connector....

  • Recommended Trailer Hitch Receiver and 7-Way Wiring Harness For a 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...

  • 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 Tekonsha Prodigy P3 Brake Controller on 2018 Buick Enclave
    The Tekonsha Prodigy P3 Trailer Brake Controller # 90195 referenced in your question is an excellent choice and exactly what I would have recommended. 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. In order to install the P3 brake controller, you will just need to connect the 4 wires from the controller to the 4 blunt-cut wires that will...

  • Parts Needed to Tow a 5000 Pound Travel Trailer with our 2021 Traverse AWD LT 3LT
    To figure out how much your 2021 AWD LT 3LT can tow, you will need to check the inside door jamb on the driver side. There will be a sticker with all the capacities the vehicle can handle. If it does say you can handle the 5,000 pounds, the Curt # CU29FR will definitely be a good option. This is rated up to 5,000 pounds towing and 750 pounds of tongue weight. You will also need some wiring to get all the lights working, but this will depend on if the trailer has brakes or not. If the...

  • 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 a new...

    The trailer hitch I recommend for a 2022 Buick Enclave is the etrailer Trailer Hitch Receiver part # e56YR. This hitch installs behind the bumper so it will be completely hidden while not in use. It features a bolt-on install without any drilling required. It has a class III rating with a 2" opening that will be great for hitch mounted accessories like bike racks and cargo carriers or for towing. If you will be towing then you'll also need a few other things such as the T-One Vehicle...

  • 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...

    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.

  • 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.

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).
