  • Provides a 7-way, blade-style trailer connector at the back of your vehicle to power your trailer's signal lights
    • Designed for use with a factory tow package

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.

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:

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:

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.

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.

No problems with it.



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.

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!

  • Do Fuses Need to Be Installed on 2018 GMC Acadia to Install 7-Way Kit # 118276
    When installing the T-One 7-Way kit part # 118276 on your 2018 GMC Acadia no additional fuses would need to be installed under the hood of the vehicle. It simply plugs in like the install video and instructions I attached below show and you're set.

  • Differences Between Available Trailer Hitches for 2020 Chevy Blazer
    The major differences between the Curt # C13418 and the Draw-Tite # 76023 are the hitch capacity, the way they install and the difficulty of the installation. The Curt hitch has a 5000 lb towing/750 lb tongue weight capacity, while the Draw-Tite has a slightly lower capacity at 4500 lb towing/675 lb tongue weight. Both hitches install so that the receiver extends through the removable panel in the bumper, but the Curt installs from underneath, and will take about 40 minutes for a professional...

  • How to Remove Access Panel and Install a Brake Controller on a 2018 GMC Acadia
    Your 2018 GMC Acadia actually has blunt cut wires for you to splice in a brake controller like the Tekonsha Prodigy P3 # 90195. The last Acadia to use the Adapter # 3026-P that you referenced was the 2017 Limited which was the same as the 2016 model year. The 2017 New Body and newer have the blunt cut wires up under the dash. I took a look at the online version of the owner's manual for your 2018 Acadia and on page 278 it says that the blunt cut wires can be found above the parking brake...

    The reinstall the rear cover on your 2021 GMC Acadia you will need to trim the cover for the Draw-Tite Max-Frame Trailer Hitch Receiver # 76023. A 3" x 1-1/2" section must be removed for the cover to mount, I have included a picture of this. Once trimmed you will be able to slide the cover back into the mounting tabs and secure it with the factory hardware.

  • Differences Between Available Trailer Hitches for 2020 GMC Acadia
    The main difference between the two is that the Draw-Tite Class III, part # 76023 is mostly concealed behind the bumper, more like the OEM hitch would be, and the Curt # C13293 installs so that the receiver tube is right under the rear bumper fascia. Because of this, the Draw-Tite offers a better appearance as well as a couple of inches of additional ground clearance. I've provided you with side by side photos of what the hitches would look like once they're in place, as well as with some...

  • Trailer Hitch and Wiring for a 2020 GMC Acadia
    We have everything that you need to start towing with your 2020 GMC Acadia! I recommend using the Draw-Tite Trailer Hitch # 76023 because it mounts behind the rear bumper and has a very clean look with the lower panel removed. Then for wiring I recommend pairing the T-One # 118276 with the Hopkins # HM40975 which gives you a plug and play wiring kit with both 4-Way and 7-Way connectors. I have linked installation videos of the trailer hitch and wiring on a 2019 Acadia that you can reference. To...

I have linked an installation video below so you can see the installation property and what the final product will look like.

It will use existing holes in the vehicle's frame for a no-drill installation and features a towing capacity of 5,000 pounds. I have attached an installation video that you can also use for reference.

  • Recommended Hitch for a 2022 GMC Acadia SLE
    The best hitch for your 2022 GMC Acadia is going to be the Draw-Tite Hitch item # 76023. This hitch is custom fit and bolts to your GMC with included hardware. I really like the Draw-Tite 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 4,500 lbs towing capacity, and a 675 lbs maximum tongue weight. It can be used with a weight distribution system but this will not increase...

  • Trailer HItch and Wiring Recommendation for 2018 GMC Acadia
    For your GMC Acadia the best hitch option we have is the Draw Tite part # 76023. The reason I recommend this hitch is that when not in use you can install the bumper cover on top of it and it would be totally hidden. Then for trailer wiring the T-One kit part # 118720 is the best option for if you need a 4-way or part # 118276 for if you need a 7-way. This is our best and most reliable brand of trailer wiring so we recommend it the highest. If you wanted to do some towing you might be...

    For your 2022 GMC Acadia AT4 you will need the Draw-Tite Max-Frame Trailer Hitch Receiver # 76023. Both the Curt # C13293 and our etrailer # e36AR will not fit the AT4 trim. 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...

  • Recommended Trailer Hitch Receiver and Wiring Harness For a 2023 GMC Acadia
    I recommend using the Draw-Tite Trailer Hitch Receiver # 76023 on your 2023 GMC Acadia. This receiver fits behind the factory cutout in your rear bumper fascia hiding it when not needed. You will need the T-One Vehicle Wiring Harness # 118276 along with a Mounting Bracket # PK12711U to attach to the tab welded on the receiver above. This will give you a 7-way connector which you can also use an Adapter # PK12716 to also connect to a trailer with 4-way flat connector.

The hitch will work perfectly on your Blazer. If you'll be towing with the hitch, you'll need a few other items to complete your towing system. You'll need a trailer wiring harness like # 118720 for a 4-pole connector or # 118276 for a 7-way trailer connector. You'll also need a # 2923 ball mount and # 19261 for a 1-7/8 or # 63845...

The hitch I recommend for your 2018 Cadillac XT5 is the etrailer Trailer Hitch Receiver # e62AR. I like this hitch above the Curt Trailer Hitch # C13285 because the Draw-Tite has slightly better ground clearance than the Curt, which is important to keep things like accessories from hitting the ground.

    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 #...

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 #...
