Features:

  • Provides a 7-way, blade-style trailer connector at the back of your vehicle to power your trailer's signal lights

Installation

This custom-fit T-One connector plugs into your vehicle's factory tow package wiring harness, which is located behind the access cover at the center of your rear bumper.


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.

All the wiring was already in the vehicle. They first sold me the wrong harness. After inspection I called and returned it for full credit and received the correct one and installed it. Its works great and the dealer had no idea how to wire the car.

Works great! dealer contractor wanted $850 to install a brake controller. E-trailer around $350



by:

Product was received long before the scheduled delivery date. Their videos made installation a breeze. I did not have to lift my vehicle nor fully drop the exhaust for install. I did however have to use a step bit to make the access larger which was no big deal. Solid purchase.

Perfect fit for my 2018 Cadillac XT5 and easy to install



by:

Yes, the hitch and the wiring harness all worked out well. Needed a friend to install the hitch. Everything was included and bolted up with no problems. Wiring harness plugged in to factory wiring.

Work well for my 2017 Arcadia which is a newly designed model. I was not sure if this item would be an exact "plug in" for my application considering my vehicle did not come with a factory trailer package. etrailer did some checking with the manufacturer to verify it would be and easy plug in. It did plug in and worked perfectly.



by:

Order came quickly and was accurate. Very simple it install and the site was very user friendly.



by:

etrailer has excellent customer service personnel, who are knowledgeable, very friendly and polite. They have timely communications about your order, shipment and delivery.

The quality of the products that I have purchased from them has always been very good.

The instruction videos are thorough and will safe you many installation problems. I just installed a hidden trailer hitch on my 2020 GMC Acadia Denali without problems by using the video as my guide.



by:
2017 Cadillac XT5

Watch video on removal of dust covers one of them is real tricky on Cadillac ZT5. My on concern about the hitch is the 7 way plug is round and the bracket is oval so they don't work together. All in all nice setup!



by:

Everything fit together perfectly. Make sure you order s mounting bracket for your connector. I forgot and wished I had at the time of ordering. Hardest part was removing the original dust covers off of car wiring harness.



by:

This product was a perfect fit for my 2019 Acadia. The instructions and even video were spot on. I couldn't ask for a better experience. Etrailer has exceeded all my expectations as an online resource. I am a mechanic and business owner and I did not expect this kind of support with video instruction from an online retailer. I will continue to use and promote etrailer to all my friends, family, and customers.

Thanks etrailer for making my life easier.

Rather difficult to install. The "how to" video helped a lot. Had difficulty removing protective caps on wiring on vehicle.

The linked install video shows the plugs being removed beginning at the 1:40 mark. If the dummy plug is hard to remove, it can be pried away gently with a small screwdriver.

  • Recommended Hitch for a 2023 GMC Acadia
    The best hitch for your 2023 GMC Acadia is going to be the etrailer Hitch item # e36AR. This hitch is custom fit and bolts to your GMC with included hardware. I really like the etrailer hitch 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 linked a couple of pictures below along with an installation video...

    Yes, the etrailer Trailer Hitch Receiver # e62AR will include the 6 fish wires to install the six 7/16" carriage bolts and square hole spacers. I recommend installing either the Tekonsha 4-Way Flat # 118720 or 7-Way # 118276 when you install the receiver on your 2022 Cadillac XT5. These will connect to the factory wiring and allow you to connect different trailers.

  • Recommended Trailer Hitch Receiver and Wiring Harness For a 2023 Chevrolet Blazer
    Yes, we have our etrailer Trailer Hitch Receiver # e36YR which fits all trims on your 2023 Chevrolet Blazer besides the premier trim. I prefer this receiver over others as it uses the matte black finish which best accents the OEM fascia trim and I find is more durable. I recommend installing either the 4-Way Flat T-One Vehicle Wiring Harness # 118720 or 7-Way T-One Vehicle Wiring Harness # 118276 when you install the receiver. The 4-way harness is best with Auxiliary Lights # C53201 and...

  • Trailer Hitch Receiver Compatible With AT4 Trim on 2022 GMC Acadia

The Draw-Tite is designed to fit as the factory receiver would and hides behind the removable fascia panel. For the wiring I recommend using the wiring from the T-One Vehicle Wiring Harness # 118276 to connect to the factory wiring. Instead of using the included 7-way you can connect the 7- and 4-Pole Trailer Connector...

You have the option of the 4-Way Harness # 118720 or 7-Way Harness # 118276. Both will connect to the factory connectors on your XT5.

  • Differences Between Available Hitches for 2020 GMC Acadia
    The primary difference between the two is the height of the receiver tube once the hitch is installed. Both hitches use a crossbar that tucks up behind the bumper fascia for a clean looking installation but the Draw-Tite # 76023 will sit higher up on the vehicle and extend through the bumper fascia as shown in the provided comparison photo. This provides for improved clearance which could come in handy if you ever back out of steep driveways. For the trailer wiring harness, use part #...

  • Is Splicing Required To Install a Trailer Wiring Harness On a 2020 Cadillac XT5
    The 2020 Cadillac XT5 has a tow package port which is located behind the rear bumper fascia.

I recommend the T-One Vehicle Wiring Harness part # 118720 if you need a 4-way or part # 118276 if you need a 7-way. The 7-way would be needed if the trailer has brakes and in which case you would also need a brake controller. I recommend the Curt Echo Mobile Trailer Brake Controller part #...

You locate connectors behind the rear bumper of the Acadia. The connectors are tucked up there pretty good but if you watch the video I attached you'll see where they are.
