Video Transcript for Tekonsha Custom Fit Vehicle Wiring - Trailer Hitch Wiring - 118287 Review

Speaker 1: Today we're taking a look at the T1 vehicle wiring harness with the seven-way trailer connector. This product is designed to fit certain years of the Chevrolet Traverse, so be sure that this is a fit for your vehicle. You can always use the vehicle fit guide located at etrailer.com. This harness provides a seven-way, blade style connector at the back of your vehicle to power your trailer's signal lights. It is compatible with four-pole, five-pole and six-pole adapters. The adapters are sold separately.

The connector features a really nice sealed design so it's going to do a great job at keeping out dirt and moisture.It features a nice spring-loaded lid, so that remains shut when nothing's connected. On the bottom side of the lid, it has a nice rubber gasket to create a tight seal when the lid is closed. It's going to do a great job of keeping out dirt and moisture, and protecting those terminals. As you can see, the wiring has protective wire loom that goes over it, keeps the wires together, it keeps them safe and protected. When it comes to the installation, it installs quickly and easily.

There's no cutting or splicing of wire needed. All you need to do is locate the connection point under the vehicle and that's on the driver's side.Find the connection point and plug in this connector. This connector is custom made for your vehicle, so it's going to be that nice custom fit. So you find the connector, plug this in, mates up perfectly and it snaps and locks together. It's a really nice design of the unit.

Once you have that plugged in you'll need to secure the excess or slack in the wiring with the included cable ties. Once your install's complete, the seven-way connector will be stowed beneath the vehicle near the trailer hitch. We do recommend using a mounting bracket to keep the connector secured and easily accessible. Mounting brackets are sold separately and they're available at etrailer.com. It's also recommended that you use a small amount of dielectric grease on all your electrical connections, like the prongs on the vehicle and the seven-pole connector itself.

That grease is specifically designed to help prevent corrosion to the connection points. It's sold separately and available at etrailer.com as well.When it comes to the mount holes, you'll see that it has pre-drilled mount holes right here on the actual connector. These are made up with the mount holes on a bracket, and we do have those as related items on this product's product page at etrailer.com. The distance that we have between these holes center on center going up and down, is 1-3/4" and center on center side to side is 2-1/2". That's going to do it for today's look at the T1 vehicle wiring harness with the seven-way trailer connector.

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

Do you have a question about this Custom Fit Vehicle Wiring?


  • Trailer Hitch Recommendation for 2018 Chevy Traverse
  • The Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C13380 sits underneath the factory bumper cover. I've attached a photo to assist. For the fit you are seeking, I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver # 76184 which will allow the bumper cover to be installed over the cover to hide and protect it when not in use. If you need the wiring, I recommend the T-One Vehicle Wiring Harness with 7-Way Trailer Connector # 118287 and mounting bracket # PK12711U. For...

  • 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...

  • 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...

  • 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...

  • Adding a 7-Way to 2019 Buick Enclave
  • 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.

  • Recommended Trailer Hitch Receiver for 2019 Chevy Traverse LT
  • The Draw-Tite Max-Frame Trailer Hitch Receiver # 75528 is only confirmed to fit models Traverse models to 2017 or 2018 limited models. For your 2019 Chevy Traverse LT, you will want the Draw-Tite Max-Frame Trailer Hitch Receiver - 2" # 76184 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. If you will be towing with this hitch, I recommend the Tekonsha T-One # 118761...

  • 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...

  • 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.

  • 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....

  • Trailer Hitch and Wiring Recommendation for 2018 Chevy Traverse
  • The Draw Tite hitch part # 76184 that you referenced is a confirmed fit for your 2018 Chevy Traverse and will work well for you but will require you to order trailer wiring separately. 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. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also...

  • 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...

  • How to Pick Out Trailer Wiring for 2018 Chevy Traverse
  • 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.

  • 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...

  • 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 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...
