Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into OEM tow package harness - no cutting, splicing or tapping required.
Features:
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 4-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 4-pole connector itself - to help prevent corrosion.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into OEM tow package harness - no cutting, splicing or tapping required.Great service. I installed the trailer hitch and wiring in 45 minutes. It was a simple install. I'm in my 70's that shows anyone can do it
Great product, easy installation, outstanding support from everyone I worked with.
Took me about an hour and the help of my son and son in law to get it done, but it saved me $800 from the dealer’s quote. 2 people could have done it, but 2 to hold the hitch up until I got the bolts started really made it easy. The wiring adapter took less than 5minutes and has worked perfectly.
I will use etrailer again.
I put a new receiver on my wife's 2020 Cadillac AT5 primarily for a bike rack but I thought I should do the wiring harness also. it was simple to install and it worked without a problem. Glad I made the choice to add the harness with the receiver.
I like etrailer products and service but the last order had a damaged box and the electrical cord does not work. I think it was smashed by the hitch,
The hitch and wiring plug fit perfect was easy to install, very pleased with the product,
Very nice quality. Installation was a snap. Video very helpful. I chose to use a step bit to enlarge the hole. Took two seconds. This is my second hitch from George. Great prices, excellent shipping time. I chose to cut the bumper cover to reinstall. Looks more trimmed out and intentional.
Don’t buy your after market parts anywhere else. Everything that we buy from e trailer is as advertised and works great.

It still works and we use it often. After a year I still stand behind my review.
The Curt hitch cost a bit more than the Draw Tite, but I am drawn to "made in USA", which Curt bragged about, and Draw Tite doesn't mention..(ie made in China).
If you look at the pictures of both hitches, you can see that the Curt hitch has a considerably larger cross member, which, I feel, can account for at least 1/2 the difference in cost.
I was sold on etrailer because of their excellent video on you tube. The installation went without a 'hitch' (ouch!). The video was very accurate and explains everything extremely well. The only difference for me was that I did not have to enlarge the 'fishing' holes; mine is a 2018 XT5, and the holes were plenty large for the bolts and doublers. I also installed the Tekonsha 118720 wiring harness, which amounts to simply 'unplugging a dust cap, then plugging in the harness' - there is absolutely no reason for this to take more than 2 minutes....(it took me 5).
As many have noted, the hitch is pretty heavy (I'm guessing 40 to 50 lbs). The weight is not such a problem, except that it is also pretty awkward. What worked very well for me was to not raise the car at all. Where the cross tube, and the receiver tube meet (middle of the hitch) is braced with a large, flat plate (safety chain eyelets) this wide plate is ideal to set on a floor jack, and the hitch balances very well. My wife 'manned' the jack, and I rolled around on a creeper guiding the hitch into place. The 'fishing' wires are long enough that they can be passed through the hitch's bolt holes while the jack is still low. Keeping the wires tight as the jack is raised guides the hitch right into position. I had to 'wiggle' the hitch a little as it passed in between the muffler and the bumper cover, then I was home free!
I didn't really time the procedure, but I would estimate about an hour, start to finish. Not bad for a "mid 60's, fat, out of shape, fella" & his 60(ish) wife!
My trailer lights use the round, 6 pin connector, so I made a bracket that bolts to the cross tube, and holds the 6 pin receptacle. I then cut the 4 pin fitting off the wiring harness, and connected the wires to the receptacle.
Also, I didn't care for the idea of having to keep up with a 7mm nut driver, so I decided to install "Southco 1/4 turn wing fasteners".
Those last two projects took almost a whole day (including nap time!)
I attached pictures of the finished project. Probably doesn't show much..I didn't take pictures as I went.....& I'm not going back!
Items were received in a very timely manner. All items were in the shipment.
I am so excited and amazed at this product. The dealership wanted to charge me $462.34 to order it, and $429.00 to install it. $891.39, and that doesn't include tax and fees. I must say YouTube is my very best friend as I install the hitch and harness in less than an hour on my 2017 Acadia, and saved [About $750]. I will order all my needed items from Etrailer. The order can within four days. Thank you and if I could give 10 stars I would. CET Thomas, Aka Batman, Byron, GA
easy easy, that's all i can say, video instructions were perfect, and it was a piece of cake to install!
Thanks so much!
good fit E.Z. to install. ETRAILER always the way to go. THANKS
Harness looks to be made of good quality wiring that will hold up for years to come. Super easy installation of just plugging it into the vehicles existing wiring without splicing any wires makes this harness a great choice. I installed it in minutes during my hitch installation on the vehicle so it made it a little simpler as the rear bumper cover was already removed.
This 4 pin connector was an exact fit for my 19 xt5. There are two plugs under the bumper that look similar. Once you remove the cap to the plug that this plugs into on your cars harness which isn't hard you plug in this 4pin into it. The length is great as well. It's literally plug and play. The 4 pin has a rubber boot that hooks onto the saftey chain anchor on your hitch and covers the 4pins when closed, this is probably the best feature. No more dragging it down the road accidentally.
Product arrived in three days. Perfect fit for my vehicle. Simple, plug-in installation, nor fishing of, or splicing of wires. I have used this company in the past with the same great products and services.

One year out and the product still performs. Easy to install! I was able to reach right in and complete the plug-in, without removing any body panels.
Great company. I submitted an email about which items I needed to purchse for my vehicle. I got a prompt and complete response to my inquiry. The follwing day,while placing my order I had an issue. So, I replied to the original email request for clarification. While waiting for I response I seen the customer service phone number so I called and got an immediate answer to my issue. After the phone call I placed my order. The next day I received a reponse to my email with an apology for not getting back to me due to him being off for the holiday. Then after the items are delivered I get another email letting me know that the items have been delivered not from the delivery company but the purchasing company. This company helped me and kept in contact with me, every step of the way.
Thank you for doing business right.
Instead of buying a new truck we bought a new SUV and purchased a receiver trailer hitch/Hiring for the SUV and a trailer to use instead of a truck, to pull the trailer that’s The best thing we ever did when we brought this product from etrailer.com A great product, cost-effective, easy instructions to follow and easy installation. A very well engineered product, I was designed exactly for Our new XT5 SUV . Easy to follow instructions I was actually easy to install. Highly recommend etrailer.com and I will use it again when my other new car arrives. A great company with cost-effective and great value automobile parts.. Keep up the good work and by the way great customer service [Thumbs up]
Everything arrived in a timely manner and well packed. The install videos made installation easy. Only took an hour or so. The wiring harness for the trailer lights was correct which made that super easy. Towed my boat the next day. I would definitely recommend Etrailer.com
The wiring harness I purchased for my 2018 GMC Acadia worked great. Was easy and quick to install. Saved me from having to wire in trailer power myself. Very straight forward. Just plug in and pull wiring to the hitch.
I installed the hitch on my XT5 today by myself (I am 85 yrs. old) but an extra pair of hands would have been helpful. It takes a little ingenuity to install it alone. I used a motorcycle jack to aid me in the installation. Removing the additional bumper cover screw to the left of the access door gives the wiring harness plate on the hitch more clearance during the install. Pull wires worked great to get hardware in place. Hitch is very sturdy. I will be using it mainly for a bicycle carrier for my E-bike.
Installing this kit was no small feat. It required disassembly of the rear bumper and taillight assemblies, as well as snaking the wiring - intelligently - all the way from the back to the front. However, once installed it's been performing admirably for over a year and 10k miles of towing.
Excellent quality connector plugs into factory harness and locks in place. Quality four wire pigtail and flat connector make for a nice wiring harness.
The hitch and wiring harness were a breeze to install using the videos. They have served well for the many times I have used my bike rack on my 2018 GMC Acadia.
I haven't used the trailer electrical interface yet but the install went perfectly. No problems.
Bought this in conjunction with my hitch and am more than satisfied with the vendor who sold the items to me.
Well made everything you need to install with great instructions that make installation a ease
