Installation

This custom-fit T-connector plugs into your vehicle's factory tow package wiring harness, which is located behind the rear bumper. Once you've plugged in the tow harness, insert the 2 relays into the fuse panel.


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


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.

This was a very easy project to put to get her and be ready for boating season. 4 bolts and the hitch was installed. The tutorial videos was a big help to make the install go without any issues.

The wiring harness install was very easy, and the operational test was successful! Kudos to your design engineers for creating such a simple process for the "do-it-yourself-er".



by:

Quick and easy install product showed up on time and in good condition



by:

I struggled with the dust cover not realizing that I needed to squeeze the clip after releasing the red tab on the dust cover Just a short session with you tube got me back on track



by:

Hitch went on easy. Wiring plugged in and works fine. Only issue I have is the relays you plug into the fuse box make a clicking noise when the brakes are applied or trunk signals are on.



by:

Installation is okay but not fond of relay clicking noise every time you apply brakes etc.



by:

Called E-trailer since the harness I ordered was on backorder. Terri (E-trailer Sales) was able to identify a substitute that was in stock. It is this exceptional service and delivery follow-up that deserves a 5-star rating or more.

Hitch arrived as scheduled. It was boxed securely with no issues. Viewed install video. Installation was very easy just as the video showed. We are very pleased with the look. Same comment about the 4-pin cable install. God Bless all...



by:

The ordering process was easy, the videos and product descriptions were exact, and the price was the best I could find. Quality products and a great experience! I plan to be a repeat customer!



by:

Worked exactly as stated, vety simple i nstallation.

Watched a video, and it went on the car just how they showed it. Plug and play.

Wiring harness was a quick plug and go to factory wiring. Drilled small hole in one of the trunk plugs on the driver’s side. Ran the wires and tucked and tied them along the frame. Sealed around the wires in the hole I drilled. Done.



by:

Very easy to order. Love the free shipp ing.



by:

Everything went exactly as expected. Took about an hour to install the hitch and wiring. I am pleased with this product.



by:

The equipment was great and the cables worked just as described. Great Product and amazing customer service



by:

Excellent customer service that other companies can only with they had.

The videos provided with each of the items I purchased to install the hitch and wiring harness were top notch and helped make the installation a breeze.



by:

Easy to hook up works well



by:


Large selection of products with plenty
of inventory options as well as very fair pricing.
The website is easily searchable & ordering is very easy.
Excellent customer service & timely when I needed some extra help. (That is a big attribute when a customer is needing more understanding of a product or has a question on shipping).
The fact that their team is fast, knowledgeable & polite is why I will refer this business to anyone. You will speak to an American when you need a question answered.
Fast shipping and their confirmation emails have added video or pdf to help you install & understand the product.
This is an excellent example of a stellar e-commerce business.
Thank you, Mindy L and the rest of the team at etrailer.com.

p.s-As a digital marketing specialist, I see lots of sites and order online almost daily-I was very impressed with the site and your team. It's not a coincidence that this was formed as a family business back in the '40s, that they saw the need for quality parts and were smart enough to see the value in local growth. They eventually targeted a larger market online and it's now the world's leading online retailer of custom-fit towing accessories.
Great job!

I was very pleased with the service provided. When my initial order was missing an item in the original packaging, etrailer shipped me a complete new item, not just the missing part. I will be doing business with them again in the future.



by:

Everything went as expected. When I hooked up the trailer, the lights didn’t work. I thought I had a problem with the new wiring but turned out the ground wire on the trailer was broken. I am pleased with this product.



by:
2017 Buick Envision

The kit is a great value and works as promised. The only reason it doesn't get five stars is that the relays provided are incredibly loud. When I am not towing, I remove the relays so that I don't need to hear the "clicks" every time I apply the breaks or use a turn signal.



by:
2017 Buick Envision

Partnered with Curt Cat II hitch. All very easy to install and worked perfectly. Not a single complaint. Only thing that could have been better was if it installed itself!



by:
2017 Buick Envision

Great product that makes hookup foolproof. The only slowdown was getting the dust cover off the vehicle plug... it was a little contrary at first. But once off, this harness is plug and play.



by:

Quick delivery, clear instructions, less than an hour to install. Hitch and harness.
Thanks for a great fit!

Exactly what I need to finish the proje ct.

  • Trailer Hitch and Wiring Recommendation for 2017 Buick Envision
    For your 2017 Buick Envision the trailer hitch part # 76080 that you referenced is a confirmed fit. Then for a 4-way trailer wiring kit you would want Curt part # C56364 that you also mentioned. 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 includes a 1-7/8 inch ball, 2 inch ball, hitch pin with clip, and a storage bag. If...

  • 2020 Buick Envision Recommended Parts for Light Trailer Towing
    I'd be more than happy to make some recommendations for towing with your 2020 Buick Envision! Here is a list of parts for you: - etrailer Trailer Hitch Receiver # e86KR - Wiring Kit # C56364 (if you have a factory connector) OR part # C59236 (if you don't have the factory connector) - No-Drill Mount Bracket # 18136 - Mounting Bracket # 18144 - Ball Mount (see attached article) I really like the matte black finish of the etrailer hitch because it blends in with any black trim on your...

  • Is Tow Package Standard on 2017 Buick Envision?
    The 2017 Buick Enclave's tow package is not a standard feature on the vehicle, it is optional. As you noted, both of the 4-flat harnesses we offer, the Curt # C56364 and T-One # 118725 require the car to have the tow package in order to work. I've added links to videos of installs and reviews of both harnesses for you to take a look at.

  • Does The Electrical Wiring Go to the Front of the Vehicle or Does It Connect in the Back?
    The 4-pole trailer connector will end up in the back of the vehicle but the vehicle connection can be found under the vehicle, on the driver side. This will allow you to connect your trailer or accessory to the 4 pole wiring right at your hitch to give it power. As long as your Buick Envision has the factory tow package, you'll need wiring harness # C56364. I've included a video of the install to give you a better idea of where the wiring is going.

  • Hitch for 2017 Buick Envision Premium With Dual Exhaust
    I reached out to my contact at Curt and confirmed that the Curt # C13292 hitch will fit on your 2017 Envision with dual exhaust. Now that you have a hitch you can use the Thule # TH9058 “Camber” 2-bike rack or the Swagman # S63380 “Trailhead” 4-bike rack. Each rack has the “Tilt” feature to allow access to the rear of the vehicle, and an anti-rattle hitch pin for a quiet ride. You could also add a small cargo carrier like the Curt # C18145 which will help you free up interior space when...

    It is absolutely safe to tow with a panoramic roof on you your 2018 Buick Envision with a panoramic roof; I also checked the owner's manual just to be thorough and there was nothing about the roof, so can tow with this vehicle without worry about your roof making any impact.
