  • 4 Flat
  • No Converter
  • CURT

Quickly and easily install a 4-way trailer connector on your Buick Enclave with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required.


  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection point behind driver's-side rear bumper
    • Plug in T-connector

  • Maximum amperage:
    • Stop/turn lights: 7.5 amps per circuit

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side rear bumper. You will have to lower your muffler to access this harness.

Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your rear cargo area.

It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.

2018 BuickEnclave

I ordered this trailer hitch wiring harness for my 2018 Buick Enclave. Website was excellent.. simple and direct. Product arrived as scheduled and the instructions were very good. Installation was exactly as shown. I would definitely order from etrailer in the future.

2019 Chevrolet Traverse

Ordered this along with a Draw-Tite hitch for my 2019 Traverse LT and could not be happier. I installed the T-Connector while installing the hitch and it was a plug and play. Installation took all of 30 seconds. Absolutely satisfied with Etrailers service and products.

2019 Chevrolet Traverse

Harness was exactly as described. It fits and works perfectly. Had everything I needed. I was even more impressed with the information you guys supplied. Step by step details on the processing of my order and videos on how to install the harness. It was all very helpful. I would definitely order from you again.


Actually a great buying experience. Shipped when they said it would and I received it a day earlier than expected. Great service. Everything was packaged well and in good shape when it arrived. The package tracking system was as good as I ever seen. Totally simple! Would recommend this company.

2020 Chevrolet Traverse

The product that I ordered was correct and on time!


Ordered on a Friday delivered on Monday. Installed easily.
Could not have better service and the best part is the hitch was made in the USA.
Thank you etrailer.

  • Hidden Trailer Hitch Recommendation for 2021 Chevy Traverse
    For your 2021 Chevy Traverse the hitch I recommend is the mostly hidden Curt part # CU29FR which is only visible when you remove the rear bumper cover so it's totally hidden when not in use. I attached an install video for this for you to check out as well on a similar Traverse. To add a 4-way trailer wiring harness you'd only need the part # C56394 which installs very easily and you'd be set. Install video for this is attached as well.

  • Trailer Hitch And Wiring For 2018 Buick Enclave Essence
    Excellent question! Personally I recommend the Draw-Tite MaxFrame # 76184 which is a direct fit for your 2018 Buick Enclave Essence. Not only is the Draw-Tite MaxFrame a super reliable and excellently built product but it is also conceals very nicely when not in use due to its recessed design; which, allows it to sit behind the rear fascia. Additionally, a fine choice for wiring would be the Curt T-Connector Vehicle Wiring Harness # C56394 which is a super easy, plug and play harness. If...

  • Trailer Hitch And Wiring Options On 2021 Chevrolet Traverse
    A hitch and trailer wiring can certainly be installed on a 2021 Chevrolet Traverse. The Draw-Tite Class 3 Trailer Hitch Receiver # 76184 would be a great choice; this is confirmed to fit all models of the 2021 Traverse. It has a max towing capacity of 5000lbs, and a max tongue weight of 750lbs. As far as the trailer wiring, I would go with the Curt T-Connector Vehicle Wiring Harness 4-Pole # C56394. This is also confirmed to fit all models of the 2021 Traverse. It does not require...

  • Trailer Hitch and Wiring Recommendation for 2021 Buick Enclave
    For your 2021 Buick Enclave the trailer hitch I recommend is the Curt Class III part # CU29FR which can be hidden when not in use and also has great towing capacities. I attached an install video for you to check out. Then for 4-way trailer wiring you'd want the part # C56394.

  • Does the Hands Free Lift Gate Still Work On a 2019 Chevy Traverse Premier with Curt Trailer Hitch
    The Curt Trailer Hitch Receiver part # C13380 which is a fit for a 2019 Chevrolet Traverse Premier and does not require removal of the rear bumper will still allow for use of the hands free life gate feature. In order to use the hands free life gate feature you simply need to place your foot on either side of the receiver tube opening. There are some vehicle/hitch combos that pose more issues for the hands free life gate feature than others but this is not one of them and will still work...

  • Upgraded Tow Package for 2021 Chevrolet Traverse
    To upgrade your 2021 Chevrolet Traverse's towing package I recommend going with the Curt Trailer Hitch Receiver item # CU29FR. This is a custom fit 2" receiver that installs without any drilling. This is a Class III receiver with a maximum gross trailer weight of 5,000 lbs and tongue weight of 500 lbs. I have attached a picture to show what this hitch looks like installed on a Traverse. For your trailer wiring functions I recommend the Curt T-Connector Vehicle Wiring Harness with 4-Pole...

  • Complete Towing Setup For A 2022 Chevrolet Traverse
    Yes, the Curt Trailer Hitch Receiver # CU29FR does fit your 2022 Chevrolet Traverse. This hitch has a maximum towing capacity 5,000-lbs and a maximum tongue weight capacity of 750-lbs. I recommend that you check your owners manual, and refer to your vehicles maximum towing capacity, and compare that number to the hitch and use the lowest rating between the two. If you want a complete towing setup, you'll also need wiring # C56394 and a ball mount # C45030.

  • Recommended Brake Controller For A 2018 Chevrolet Traverse
    When it comes to installing a brake controller in your 2018 Chevrolet Traverse with factory tow package I recommend The Curt Echo Wireless Trailer Brake Controller - 1 to 2 Axles - Proportional # C51180. This controller automatically adjusts trailer's braking based on deceleration of tow vehicle. The controller has a fast, plug and play installation with no tools required. The controller has a user-friendly, app that lets you connect, monitor, and control all of your trailer's braking...

  • Best Hitch for a 2022 Chevy Traverse RS
    I would be happy to help you. The best hitch for your 2022 Chevy Traverse RS is going to be the Draw-Tite Max-Frame Trailer Hitch Receiver item # 76184. This hitch is custom fit and bolts directly to your Traverse with included hardware. I chose this hitch over the other options because it has a built in bracket that allows you to attach your wiring harness using just the Tow Ready Mounting Bracket item # 18144. I have linked an installation video for this hitch below. To control your...

  • Towing Capacity for 2018 Chevy Traverse AWD
    5,000 lbs appears to be the weight capacity of the 2018 Chevy Traverse if it has the 3.6 liter V6 engine and 1,500 lbs if the engine is the 2.0 4 cylinder. Those figures are the fully loaded capacity that your truck can tow. If you are going to be at the capacity of vehicle a weight distribution system would be recommended. For that I recommend the Strait Line part # RP66082 which has a tongue weight range of 200-600 lbs and features the best sway control designed to fight sway before...

  • 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...

  • Does the Tekonsha TK94FR Require WIFI to be Used?
    The Tekonsha Prodigy RF Wireless Trailer Brake Controller # TK94FR does not require WIFI to be used. The controller in the cab will connect to the actuator box via Bluetooth. That being said, if your vehicle did not include a 7 Way plug, it will need to be added to get the controller working. If this is the case, you will need to start with a 4 Flat harness, like the Curt # C56394. The 7-Way RV Upgrade Kit # ETBC7L will piggyback off the 4 Flat and will then get the # TK94FR working properly.
