Installation

This custom-fit T-One connector plugs into your vehicle's factory tow package wiring harness, which is located beneath the vehicle, near the frame rail on the passenger's side. Once you've plugged in the connectors, insert the included fuses and relays into their locations in the fusebox, which is located in the engine compartment.


Once installation is complete, the 4-way flat 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.

Video Transcript for Trailer Wiring Harness Installation - 2017 Chevrolet Traverse

Today, on our 2017 Chevrolet Traverse, we're going to take a look at and also show you how to install the T-1 Vehicle Wiring Harness, with the 4-Pole Flat Trailer Connector. Part number is 118270. Now, this is what our wiring kit's going to look like. This is a really basic, straight-forward installation. We're going to have the fuses and the relays that we need to activate the plug that's on the back of the vehicle. Once activated, that's going to send out our right turn and brake, our left turn and brake, our running lights, and it also give us our ground, through our wiring, right back to our 4-pole flat trailer connector. Now, this 4-pole flat connector's going to work out great for your standard utility trailers, and also good for cargo carriers.

Now, this kit gives us a maximum of 7.5 amps worth of output for our running lights, and also 7.5 amps worth of output for our turn signals and for our brakes. That's going to give us plenty of power to power all of the lights on our trailer without any issues. Now, this wiring is designed to fit with vehicles that are equipped with a tow prep package, or with the tow package prep. To find that, to locate that, we're going to come over to the passenger side. We've got the exhaust that comes out here. We're going to tuck in, right inside, in between the edge and the chassis, and we'll look right up on the body of the car.

It's going to be located right there at the end of my screwdriver. Now, as long as that's there, you're going to be fine to use this wiring kit. Now, if your vehicle is not equipped with that plug, we recommend using part number C56181. That's going to be a 12-volt hard wire, for full wiring kit. You'll just want to ensure that you do not have rear air conditioning. We're going to take the larger side of our plug and we're going to apply a little bit of dielectric grease, here.

This just helps to keep out moisture. It's going to prevent dirt from getting in there and causing corrosion down the road. That part number is 11755, if you don't already have some. We've got it available on our website. Then, we just want to reach up and in, and plug this plug up into the factory plug.

You'll hear a little click, and then you'll want to push and pull on it, and make sure it's not going to separate. Now, what I like to do is bring my wiring around the back corner of the actual body of the vehicle, and I'm going to pull it so it's nice and secure, and then zip tie it off to my hitch. That's going to prevent the wiring hanging down and getting close to our exhaust that might cause damage. Now, for zip tying to our hitch, you can use a couple of the zip ties that came with the kit. You'll have to just kind of daisy-chain them together, or what I've got, one single longer zip tie that we'll use. All right. That should keep that nice and secure. That'll prevent it from hanging down. We'll trim the end off of that to keep it nice and neat. Bring it over here. Close to the receiver tube opening is where we like to keep it. You'll want to decide how much of that you want to be out. That's usually a good length to connect most of your trailers. Then, I'll use another zip tie, go around my hitch here once again. You'll see we've got a little bit of excess here, which is good. If we need to extend this, we just kind of pull out on it. To keep it tucked up there and out of the way, you guessed it, another zip tie. Just like that. Now, for using your wire, just have it hanging out here, plug it into our trailer, cargo carrier. We'll be set. When you're done, I like to just kind of tuck them, you see, tuck that right up and over, bring my plug down. It's got that nice dust cover on it. It's going to protect our plug from moisture and dirt getting in there and causing it to get corroded. Just store it just like that, that way we don't have to worry about it hanging down or anything, pretty clean look. What we want to do is now remove the cover that's on the fuse block here. This is going to be on the passenger side, under the hood. You just need to press in on these little tabs, one, two, and three. That'll allow us to remove it. Now, inside here, we're going to find a few areas we need to place our fuses into. We've got the F-7 slot. That's going to be on this front edge, right here. That needs a 10-amp fuse. Get that popped in. Now, we'll need to move down to where we have these three relays. Right over there, there's two more empty slots. One's going to be the F-17, the other one, the F-21. Two more 10-amps for those. That'll be our 21 and our 17. Then, we'll come all the way over to this driver side edge. You have a relay right here, if we look behind that, it'll be the F-41 spot. That also needs a 10-amp red fuse. Now, we can move on to our 30-amp fuses. We're going to have two of these to put in place. One needs to go here in the F-30 slot, one in the F-34 slot. These are going to be green, 30-amps. Now, we'll get our relays put in place, they're going to go in these two open areas. We've got one open area here, one open area here. That's going to be the R-15 and the R-16. We'll turn these to where the thicker side is facing either the driver or passenger side, then we'll slide those in. Now, we can put our cover back in place, and test out our wiring. Now, to run our test, we're going to use part number I26. It's just a standard 4-pole tester. We'll run through the lights and we should see the corresponding light light up. We're going to start by turning on our running lights. We'll do our left blinker, do our right blinker, and our brakes. We had everything working as it should. That's going to complete our installation of the trailer-ready, T-1 Vehicle Wiring Harness with the 4-Pole Flat Trailer Connector, part number 118270, on our 2017 Chevrolet Traverse.

Plugged right in and worked right the first time, took about 15 minutes to install, and only took that long because I fished the wiring over the subframe to get it completely away from the exhaust. Came with extra fuses and relays, as my vehicle already had the fuses and relays installed. Shipping was prompt, and etrailer personnel answered my questions thoroughly, making this a smooth job. THANKS! Wish I could take pictures, but imagine in your mind the dirty underside of my car with clean trailer wiring firmly ziptied in place. 563444

Received my Traverse hitch in 3 days , thought that was great . The hitch was a defective Draw-Tite 75528, the end mounting flange on one side was welded at an incorrect angle and the hitch would not bolt to the frame rails. I called etrailer about this and they shipped out another hitch at n/c in 3 days with a pre-paid UPS label to return the defect . That was a fair option to me , the replacement part was correct and it fit properly , the only thing was the hole for the ball mount hitch pin was undersize and I had to use a round file to open it up to fit the pin through it . I guess in Mexico they use a smaller pin size to hold the ball mount on The customer service at etrailer was great, thanks Niki 401037

It went on as easy as it looks in the video, which is surprising for most products you buy online. You can't go wrong with putting it on, as long as you follow the instructions and watch the videos they have on here. 349883

Gave this order 5 stars for the prompt service and the product was just as described. I ordered a drawtite Hitch and wiring connector for my 2013 Buick Enclave. The hitch and wiring connector arrived quickly. I also ordered a bracket for the four wire connector within 10 minutes of the first order, which was shipped first, it was shipped by the USPS. All of the items fit perfectly and was easy to install following the excellent instructions. Great job! Recommend etrailer for all your towing needs. 416779

This was one of the most easiest installation I've ever done! Thank you etrailer! The parts work, the instructions were clear and accurate on the video and in the installation procedure and the kit worked as advertised! I highly recommend it! My only recommendation for improvement would be to add an 8 to 14 inch insulating sleeve for the cable that would be nearest to the muffler because it gets hot and should the cables get loose and sag to it. I've had this part for over a year but have installed and used it the last two months. 644269

The trailer hitch was also very easy. 6 bolts and it was installed. Again I have installed way to many. Went right in to place directions were very clear. It took me and my son about 30 mins to install both the wireing harness and the hitch. 619872

Excellent product, easy to install less than 20 minutes. Online videos are very helpful. The only critique is that the zip ties are too short to be of much use. I used much longer ones to secure wiring to the hitch receiver. 566820

Great package with the hitch, the wiring harness and the mounting tab for the wiring. Make sure that when you reach up in the rear passenger fender that you get the plug pushed in completely . I held the plugs together with my left hand and used a long thin pry bar with my right to reach up in and push it until it clicked into place. I will be buying all my stuff from etrailer.com going forward. 561620

I've had to run wires in the past , this kit makes it incredibly easy. Plug it in to the factory wire , add the fuses in the designated spots on the instructions, and your done. Easy to follow instructions! Also had the wife ask the dealer how much for them to install a tow package. 750 was there quote, said they had to run wires from the fuse box.... all BS. the wires are already there you just reach up by the muffler and plug it In. Awesome product! 547941

Instructions were great, and they included an extra relay and extra 30A fuse. Easy to install, and I was able to do so without pulling the wiring harness loose, so it’s still nicely secured. Only complaint is the included zip ties did not wrap the frame completely, but I had my own that did. 545183

My only real issue with this product is the zip ties that come with the kit are almost completely worthless. They're too small to fit around the hitch bars, so trying to secure the wiring down was basically impossible unless you connected two zip ties together. Other than that the kit was great and very easy to install. 540528

  • Adding a Trailer Wiring Harness to a 2015 Chevy Traverse LT without Factory Tow Package
  • You have a couple of options for adding a trailer wiring harness to your 2015 Chevy Traverse that did not come with the factory tow package. If your trailer has a 4-Way flat connector on it then you can use # 118270 to add a mating 4-Way to your Traverse. If the trailer requires a 7-Way then you can install # 118271. In either case the harnesses include the fuses and relays to make the harnesses fully functional on your Traverse. I have linked videos showing example installations of...

  • Trailer Wiring Needed for 2017 Chevy Traverse with Rear Air Conditioning Unit
  • Since your 2017 Chevrolet Traverse does not have the factory connector but does have a rear air conditioning unit I recommend first checking to see if you have the factory tow package. You can locate the plug for the Tekonsha T-One # 118270 at the rear passenger side as is shown in the attached installation video. If you don't have the factory tow package then you will want to go with the Hopkins # HM11141150. I spoke with my contact at Hopkins who said that he hasn't heard of having...

  • Recommended Trailer Wiring for 2017 Buick Enclave
  • For your 2017 Buick Enclave, I recommend the T-One Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector # 118271 which will connect to factory wiring and includes the fuses and relays to activate the tow package even if your vehicle did not come with one. This wiring harness will be tucked up under your side panel underneath on the passenger side which is difficult to see in the attached a video of the similar Chevy Traverse.

  • Trailer Hitch Receivers are a custom fit for each vehicle, sometimes a certain series of a make/model are a different fit. This is the case with the with your 2017 GMC Acadia Limited. The frame on your specific vehicle requires a different mount style than that of the Draw-Tite # 76023 you referenced. The hitch receiver I recommend for your vehicle is the Draw-Tite Max-Frame Trailer Hitch Receiver Class III - 2", # 75528. This is an easy bolt on installation. The complete hardware...

  • Trailer Towing Setup Recommendation for 2014 Buick Enclave
  • You are on the right track! The Draw Tite hitch part # 75528 is a confirmed fit for your 2014 Buick Enclave as well as the trailer wiring kit # 118270. The wiring mount part # 18144 will also give you a place to mount the 4-way that bolts to the bumper. The ball mount part # C45036 that you referenced is would also work well if you need 2 inch drop. I attached a help article that details how to pick out a ball mount drop as well.

  • Trailer Wiring Harness Recommendation for a 2013 Chevy Traverse without Tow Package

I have added a link to a video of this hitch being installed on a '15 Enclave for you to take a look at.

If that harness you found has a connector on it then what you can do is use a circuit tester such as # ALL640595 or a meter if you have one and test the pins in that connector.

For wiring, the basic 4-pole setup for your Acadia is part # 118270 but if you want to have a 7-way along with this 4-pole you will install the...

  • Trailer Wiring Harness and Other Parts to Tow a Trailer with a 2017 Chevrolet Traverse with Rear AC
  • From what we have found all the Chevrolet Traverse models from 2017 like yours have the factory tow package connector under the vehicle near the frame rail on the passenger's side even if it doesn't have the tow package. I've attached a picture that shows the connector you need to find. If your Traverse does have this connector you can use # 118270 for a 4-way trailer connector. This also includes the fuses and relays you'll need to install to activate the tow package. I've linked a...

  • Correct Wiring Harness for a 2017 GMC Acadia Limited Without the Tow Package
  • Good question! The T-One Vehicle Wiring Harness # 118270 will fit your 2017 GMC Acadia Limited whether it has the factory package or not. The plug should be located at the rear of your vehicle behind the rear passenger side tire (see attached photo). If you had the tow package you would simply make this connection and be done with it but since you don't you just need to use the fuses and relays that come with the T-One to activate the wiring. We actually do this exact thing on another...

  • Trailer Hitch and Wiring Recommendation for 2017 Chevy Traverse
  • Let's first start with a trailer hitch for your 2017 Chevy Traverse. For that the best option is the Draw Tite part # 75528 which is a confirmed fit and would work well. It has best price and towing capacities. I attached an install video for it for you to check out as well.

  • Trailer Wiring Recommendation for a 2015 Chevy Traverse with Rear Air Conditioning
  • The trailer wiring kit you would want for your 2015 Chevy Traverse that has the rear AC is the Tekonsha part # 118270. This wiring harness can be used as an OEM replacement, but it also includes the fuses and relays to activate the tow package if your vehicle was not equipped with the tow package. This will be a plug and play model that will install easily and would not interfere with the AC. The Hopkins kit you referenced would work but is a universal hardwire application. Check...

  • Which 7-Way Trailer Connector Fits a 2016 Chevrolet Traverse with the Factory Tow Package Connector
  • I looked up your previous order and you purchased the wiring harness, parrt # 118270. Since this plugged in and worked for you it means you have the factory to package connector without having the complete tow package. This is good news because all you need to add a 7-way trailer connector is part # 118271. This will give you a 7-way and replace your 4-way plugging into the same place. So you don't need the # ETBC7 kit afterall.

  • Parts Needed to Add a Trailer Hitch and Wiring Harness on a 2016 Buick Enclave
  • If you are wanting to add a trailer hitch and a wiring harness to your 2016 Buick Enclave I recommend installing the Draw-Tite Max-Frame Trailer Hitch Receiver # 75528 and then either the T-One # 118270 for a 4-Way or the T-One # 118271 for a 7-Way. If you would like to have both a 4-Way and a 7-Way then install the T-One # 118271 and swap out the connector with the Hopkins # HM40920. To mount the 4-Way near your receiver you need part # 18144 while the 7-Way requires part # 18138. Instructions...
