Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located above the muffler on the driver's side. You will need to lower the muffler to access the wiring harness. After plugging in the connector, route the 7-way end of the harness along the inside of your bumper toward the center of your vehicle.


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 plug on your automobile and the 7-pole connector itself - to help prevent corrosion.

Plug and play, easy to mount and looks factory, will need to install mount plate reversed to have enough clearance for plastic hitch cover to latch. Very happy

Good customer service but should not be charged separately for the plug ins when you bought the hitch you need both to pull a trailer down the road



by:

Very helpful emails and instructions



by:

Excellent product!



by:

The electrical adapter was easy, the bracket holes did not match the7-way adapter. The description of the bracket said”7-way, not even close.

Excellent product, plug and play, easy peasy. Zip ties are WAY too short. Got into my own Zip tie stash!

Exactly the right cable length to go from the factory plug to the hitch area. Smoothly and firmly connected into the factory plug.

  • Trailer Hitch Receiver Confirmed To Fit The 2024 Buick Enclave
    Yes, the Curt Trailer Hitch Receiver # CU29FR will fit your 2024 Buick Enclave. This receiver is designed to fit behind the removable rear fascia panel providing a clean factory look which can be hidden when not needed. You can combine this with either the 4-Way # C56394 or 7-Way # C56393 depending on which connector you may need for the trailer you could tow. If you only intend to use this with hitch mounted accessories the 4-way will allow you to use Auxiliary Lights # C53201 in the...

  • Most Concealed Hitch for a 2023 Chevy Traverse
    The most concealed hitch for your 2023 Chevy Traverse is going to be the Curt Trailer Hitch item # CU29FR. This hitch is custom fit and bolts to your Chevy with included hardware. I really like the Curt item # CU29FR because it installs behind your rear bumper cover and can be completely hidden when you are not towing. This is a class III hitch with a 2" receiver. It has a 5,000 lbs towing capacity, and a 750 lbs maximum tongue weight. I have attached a couple of pictures below, along...

  • Recommended 4-Way and 7-Way Connectors for a 2023 Chevy Traverse
    I have both a 4-way and 7-way connector that are custom fit for your 2023 Chevy Traverse. They are the 4-Way Curt T-Connector Vehicle Wiring Harness item # C56394 and the 7-Way Curt T-Connector Vehicle Wiring Harness item # C56393. These custom-fit T-connectors plug into your Traverse's wiring harness, which is located above the muffler on the driver's side. I have linked a couple of installation videos for both below. Neither one of them have a back up alarm. The only option to purchase...

  • Recommended Hitch for a 2024 Buick Enclave
    To add a hitch to your 2024 Buick Enclave, I recommend the Draw-Tite item # 76184. This hitch is custom fit and bolts to your Buick with included hardware. I really like the Draw-Tite hitch item # 76184 because it installs behind your rear bumper cover and can be completely hidden when you are not towing. This is a class III hitch with a 2" receiver. It has a 5,000 lbs towing capacity and a 750 lbs maximum tongue weight. If you are planning on towing you will also need a wiring harness...

  • Recommended Trailer Wiring Harness For A 2021 Chevy Traverse
    Hi Motty, 2021 Chevy Traverse's have a factory connector at the back to plug into so you can go with either a 4-pole # C56394 or 7-way # C56393 connector depending on your needs. Personally, I'd go with the 7-way and if you need to connect to a 4-pole trailer wire harness you can just use an adapter # PK12716. Having a 7-way will allow you to install a brake controller and tow trailers with brakes so it's just going to offer more versatility. To mount the 7-way connector I recommend...

  • Is GM Tow Package Or Etrailer Tow Package Better For 2021 Chevy Traverse?
    If your 2021 Chevy Traverse has the factory tow package then it can tow up to 5,000lbs according to the online version of the owner's manual (I recommend checking your manual to verify). GM normally offers a more expensive hitch for the factory tow package and it usually does not hold up as long as aftermarket options. It looks like the factory tow package, along with the etrailer Trailer Hitch Receiver # e56YR, are rated for up to 5,000lbs towing capacity and the etrailer hitch is rated...

  • Parts Needed To Tow a Trailer With Brakes With a 2020 Chevy Traverse
    It sounds like you might be looking to tow a trailer with brakes using a 2020 Chevrolet Traverse. If that is the case then I have some great options. That said, there are no wiring adapters for the brake controller which is why I recommend the Curt Echo Wireless Trailer Brake Controller part # C51180 because it does not require splicing. In order to use the Curt Echo you'll need the Curt T-Connector Vehicle Wiring Harness part # C56393 and Mounting Bracket for 7-Way part # 18138. I do...

  • Will Curt Echo Need Additional Wiring After Installing Curt 7-Way On 2020 Buick Enclave
    Installing the Curt # C56393 on your 2020 Buick Enclave will give you a working 7-way at the rear of your vehicle. Since the Curt Echo # C51180 installs by plugging in-line with the 7-way at the back there is no need for additional wiring inside of the cab of your vehicle. The only thing you will need to do is plug in the Echo, plug in the trailer, and pair it with your phone through the app and you're all set.

  • 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...

  • How To Connect Trailer With 5-Flat To 2023 Chevy Traverse
    Hello John, thanks for getting in touch. 4-flat connectors like the T-One Vehicle Wiring Harness # 118761 you were looking at do not have a reverse light function. You can reverse light function my converting it to 5-flat using the Curt Trailer Connector Adapter # C57187. Reverse light function should be wired to the factory connector so a better solution is you can add a 7-way to the vehicle and use an adapter like part # A10-7275VP. I see that you were looking at parts for a 2023 Chevy...

  • Recommended Wiring Harness for a 2020 Chevy Traverse
    The Curt T-Connector Vehicle Wiring Harness item # C56394 for a 4-way or item # C56393 for a 7-way is what I recommend for your 2020 Chevy Traverse. These are custom fit and quite a bit easier to install when you're putting the hitch on. Just like the Draw-Tite Hitch item # 76184 they require the rear bumper cover to be removed. If you ever plan on towing a heavy trailer like a camper you will want the 7-way Curt Wiring Harness item # C56393 because it can control trailer brakes. The item...

  • 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...

  • Trailer Hitch Receiver and Vehicle Wiring Harness For a 2024 Buick Enclave For Towing a Trailer
    First you will need the Curt Trailer Hitch Receiver # CU29FR for your 2024 Buick Enclave. This receiver will sit behind the factory removable panel on your rear bumper so you will have a clean appearance. Depending on your trailer you will need either the 4-Way # 118761 or 7-Way # C56393 for the wiring. The 4-way is most commonly used on small utility and boat trailers. For trailers with electric brakes you will need the 7-way along with a Brake Controller # C51180. This controller plugs...
