Quickly and easily install a 4-way trailer connector on your GMC Terrain with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required.
✔ Confirmed to fit your 2012 GMC Terrain
This custom-fit T-connector plugs into your GMC Terrain's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness.
Once installation is complete, the 4-way connector will be stowed beneath your GMC Terrain, 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.

Today we're going to review part number 56094, this is the Curt T-connector vehicle wiring harness with the 4 way flat trailer connector. Now this is a custom fit part number, it is designed to fit the Chevrolet Equinox and GMC Terrain starting in 2010. What I would recommend to do is go to our website, use our fit guide, put in your year and model vehicle, and it will show you if this part will work for your application. Now this will provide a 4 way flat trailer connector at the back of your vehicle to power your trailer signal lights. This does connect quickly and easily there is no cutting or splicing of wires they just all use pug in T-connectors. Basically what you'll do is locate your connection points which are usually behind your taillights.
Plug in your T connectors, run this to the back, you'd be all ready to go. It does also come with this nice dust cap to use on your 4 way, so basically what you would do is wrap this around the 4 way itself, push it into place, and then just leave it attached. And then when you're not plugged into your trailer, you just put this dust cover over it and it protects those terminals from any damage or weather. This part is made in the USA, it does come with a nice set of detailed instructions that tell you and show you with pictures where it installs, comes with a screw for the ground wire and some zip ties to take up any slack of wire you might have. Basically what you would do . This custom fit T connector will plug into your vehicles wiring harness and that usually located behind your drivers side and passenger side taillights. So what you would do, see this T connector with the yellow wire in it This will go to your drivers side.
Unplug your taillight, plug this into there. Go to your passenger side, which is the green wire side, plug that in the same way. Now you do have on the passenger side an extra white wire with an eyelet on it, that needs to be grounded. You can use this screw to get a nice clean ground. Once they're all connected run this out to the back and when you're ready to you can just plug this into your trailer and you're ready to go.
Now we do recommend that when you install any type of wiring that you use a small amount of dielectric grease on all your electrical connections. This will help prevent corrosion. But that should do it for the review on part number 56094 the Curt T-connector vehicle wiring harness with the 4 way flat trailer connector. .
Average Customer Rating: 4.9 out of 5 stars (298 Customer Reviews)Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required.

I've seen many aftermarket hitches that are obviously not built for a specific car, and they look terrible when installed. The hitch I purchased from Etrailer.com was a perfect fit for my car. It was built by Curt Mfg., and was surprisingly easy to install. I had the wiring harness installed in about 45 minutes, and it just plugs into existing wiring (no splicing). And the hitch bolted onto the car with no cutting, drilling or hammering. It was done in about an hour. The finished installation looks like it came with the new car ! The process was much less expensive than having the dealer install it. Excellent product !! 137454

The product was just like what I saw in the video and just as easy to install. I installed the trailer hitch and the wiring myself with my brother's help. We finished in less time than was estimated and checked out the wiring with a voltmeter. Everything worked just fine. Thanks for the installation video. I would not have tried the install myself if it were not for your video. Thanks. 131864

This wiring harness is very easy to install. I had a bit of trouble getting the tail lights out of our 2012 equinox but with a a second set of hand they slipped out without doing any damage. I used extra zip ties and wire loom to help protect the wire. Be sure to keep it away from the exhaust if you have a V6 with duel exhaust tips. I modified a Curt rubber tube cover to secure the harness to the receiver. I made sure to leave extra wire in behind the hitch so that I can pull it through when I need it. 63065
Excellent product, very easy to do. I am not a fan of cutting into existing wiring, so this kit was the answer. It took less than a hour. The Curt 2 inch hitch for my 2010 GMC Terrain was also an easy installation. All hardware was supplied and extra for situations that maybe encountered, i.e.., bolt holes not threaded from factory. The 2010 Terrain was all bolt on. What I especially like is the fact that it is totally hidden except for the receiver. 190230

Look, I have no doubt that the product is excellent. After all, it fits perfectly into and with the original equipment. The installation (I took my laptop out to my Equinox and ran through it, step by step) went without a misstep--well, I did drop a screw that held the rear light bracket in place and spent a while retrieving it from inside the car frame, but that was my fault. I also want to note that the video is correct in suggesting using longer zip ties, but I was able to make use of the provided ties, supplementing them with a few of my own. But here's the real deal: The staff at etrailer.com babysit you all the way from order to delivery and beyond. Amazon's a great way to shop, BUT I've ordered twice from etrailer and I'm convinced it is the place to go if you want the right part and SERVICE. Seriously. 135638

Got my trailer hitch today and thing went on without a hitch. All ready cleaned out the the 12 mm weld nut threads with a tap. That was a three hour job by itself. Because the threads were all ready cleaned out with a tap (there is no way a wire brush and penetrating oil would ever work). The assembly went on without a hitch. Probably took me 2 hours at a relaxing pace. Used anti- seize on all threaded fasteners. 223159

This was so easy. Everything needed was included, except for the tools needed. The instruction were great, if you follow them, nothing can go wrong. I would recommend your products to anyone and I know that they would be able to do the job and be very happy with the results. 188290
by: Glen M.08/08/2014
The product (wiring harness) was installed in about 20 minutes. The video I watched was exact and helpful. I would recomend this product to anyone with a Chevy Equinox. The hitch and wiring looks like it was factory installed. 145276

Just installed Curt Kit # 56094 on my 2011 Terrain. Instructions are simple and easy to follow. Only took about an hour to complete. Etrailer was a pleasure to deal with, I recommend them highly. 87811

Installation could not have been easier....less than 30 minutes. Fast shipping...great product. E Trailer does it again!!!! 92719

This was a cinch to install. Took me just as long to read the instructions and watch a video as it did for me to connect the wires. 186530

I recently installed the 13591 Curt hitch onto my 2015 GMC Terrain with T connector harness. The hitch fit perfectly and was easy to install. As for the T connector harness, the provided connector were a perfect fit into the GM factory harness. Wire routing was easy by using the carriage bolt wire (provided with the Curt hitch) as a retrieval tool for the passenger side. The only thing I could suggest to add to the kit is a trailer connector bracket and a piece of adhesive backed foam to put between the harness connector and vehicle body. I used a piece of foam weather strip to prevent rattles caused by the connectors hitting against the body panels. 167501

I ordered this hitch & wiring kit for my 2012 GMC Terrain SLE 3.0 6 cylinder and it went on in less than 30 minutes! I ordered the hitch and wiring harness on Monday (Labor Day even) and the package arrived on Wednesday afternoon - WOW! Thank you eTrailer. 225777

Have not installed it yet, but have taken it out of the box. I watched the installation video and the wiring one. Looks simple enough 145321

I was a little skeptical at first, the car it was to go on is our tow vehicle for the motor home so it already had a harness on it from the coach, but everything snapped to gather and all is working for trailer lights, haven't checked the tow car behind the motor home yet. After some thought I did use your harness plugged into the car first, then the one to the coach plugged into it, I was told that the harness for the coach has shunts in it , something to do with back feed, true or not I am not an electrical person, so will have to do a follow up later on that one.

Perfect Fit for my 2015 Chevy Equinox. Easy install, just follow the video instructions. Take your time, be gentle with the tail light removal. Use a low torque setting on electric screwdriver for re-installation or you'll strip the nylon inserts. I used plastic flexible wire conduit to clean up the install and keep wires clear of exhaust piping. Tie-wraps provided could have been longer, if you intend to strap the wires to the hitch frame. Ground wire screw provided is flimsy, use a #8 or #10 sheet metal screw for a good ground connection. Worked perfectly the first time. 200768
by: Burke W06/07/2015
Wiring harness easy to install. Removing the tailights had its usual issues about how much pressure is needed to apply on the assembly to pop it out. I hate those plastic fasteners. I drilled a hole into the sheetmetal behind the light assembly for the ground connection. The hitch itself went in easy. I had rested the whole hitch on a bucket to get it up off the ground while I installed the 4 end bolts. Don't tighten until you instal the 2 center bolts. The wire snake worked, it should be 6" longer so you don't get nervous about pulling back thru. 201392

I need a wiring product for my 2012 terrain the the local didn't stock the right one. To order One would take three to four days and I needed it quicker then that (poor planning on my part) and they ask over double the price that I got from you. You also gave an option on shipping te and cost. I was very pleased with your service You can always purchase like products but when it comes to service your company stands out. I will be purchasing a flat tow bar in the near future and be ordering it from you. Keep up the good excellent service. Thanks Jim 52012
by: Chris M.06/28/2012
To EASY to install. I purchased this product for my 2012 GMC Terrain AWD 4 Cylinder. Just like the instructions I removed the screws for the tail lights, popped them off (you need to pull straight back and a little hard because the tail lights have straight clips behind them, they won't break, the clips go straight into the vehicle body) and clipped in the harness as directed. Too EASY. When putting the tail lights back on be cautious not to smash the rubber lining which runs above the tail lights on the vehicle itself. GREAT PRODUCT!!!!!!! 46024
Easy to install....great product. 146076
Easy to install 112621
by: Rob B05/28/2013
The wiring is very easy to install and worked perfectly for me the first time I used it. The video walkthrough was spot on, it only takes about 15-20 minutes to install and doesn't require you to run a wire up to your batterey at the front end of the vehicle. Besides installing the ground wire with the self-tapping screw, the rest of the instalation only involves plugging in the 4-way adapters to your existing taillight wiring. The product arrived as decribed and I would absolutely reccomend this product. 82234
by: Lynn K.09/08/2015
I'm very pleased with my purchase. I ordered a trailer wiring harness to install on my 2011 equinox. The etrailer website was easy to navigate. Shipping was timely. More importantly, etrailer put together a wiring harness that was very easy to install. The item was packaged neatly. No parts were missing. Clear instructions were provided with colored pictures for reference. I highly recommend etrailer and planning on doing business with them in the future. Thanks etrailer for keeping it hassle free! 224517
by: Steve w08/17/2015
Reviewed the installation videos prior to ordering the hitch and wiring harness. Followed the video instructions for a very easy install even though I was laying in the ground and used my small floor jack to raise up the hitch. Installing the wiring was really just as easy as shown in the video, only wish the zip ties were long enough to go around the braces so I had to double up to use them on the lower install. Much appreciate your expertise and very professional installation videos. 219842
by: Glen M.10/17/2014
I found the products I purchased from etrailer to be very good, easy to install at a reasonable price . I was pleased with my customer service from placing the order to delivery and follow up. I highly recommend etrailor and next time a purchase auto accessories I will start with etrailor. 156554
Pretty Easy. The Chevy Equinox tail light assembly has only two screws each. Easy to remove with a phillips screw driver. The wiring harness is pretty self explanatory. The wire coloring matched the basic wiring from the tail light, making it easy to match up. The harness has more than enough length to reach the hitch. It was a little tricky finding metal to drill for the ground but all and all a good product. The entire wiring project took me less than an hour. 143748
by: E Whitestone10/22/2011
Of the two Wire Harness's available for the Terrain and Equinox from etrailer, the Curt #56094 is absolutely the one to purchase. With this one, you do not have to run a wire all the way from the back of the vehicle to the front and make a Battery connection, like you have to with the other harness available. Excellent quality and installs easily, without the hassle of running a wire to the Battery. Curt trailer products are second to none. 25947

I ordered the class 3 hitch, plug and play wiring kit and the US flag hitch plug. I watched the youtube video ETrailer had made, followed their directions and had everything installed in1 1/2 hrs by myself. Even though they told me it would ship in 5-7 business days it was at my door within 5 days. I feel I got a fair price(didn't really shop around). Overall very happy with my purchase, it will serve me good. 182966
by: Stan S.05/09/2014
I bought this for my 2014 equinox, not being very mechanically gifted I had worry if I could actually do this but after reading what other customers had written I thought I would give it a try. Was I ever surprised at the ease of installing it. Any time I need something I will alway head straight to Etrailer.com I was so impressed with the quality and instructions I must give them an A++ and a at-a-boy 129725
by: bob class04/24/2014
I had the chevy dealer install the hitch and wiring harness. They told me that the equipment was of great quality and easy to install. I was able to do these type things years ago, but at 75, a person has to admit it's time to let the younger guy's do the work. This is the second hitch and harness I've gotten from you. I have recomended you to several of my frends. Thanks Bob C. 127132
by: wiring harness and hitch05/30/2015
very simple to install, the wiring had a great directions and simple. i found out that it is better to put the hitch on before the wiring, i had to reroute the wires after i put on the hitch, but the wire snake is the best thing i have used in a while, i fished the bolt right to the hole with no problem. it looks great, you can't even see any bars under the bumper. love it. 198780

Great product ,excellent fit ,easy install with help . Customer service is the best will recommend e trailer to everyone that needs hitches. Thank you mike S for your help ! 203323
by: Roger N.05/25/2016
I bought the wiring harness a year ago, but did not install it until last weekend when my son needed it to pull a new trailer. Along with a YouTube video the installation on our 2013 Equinox was a piece of cake! Everything needed was in the kit and all connections were color coded to match the manufacturer's. It took 35 minutes beginning to end. Great Product 251560
by: Robert M06/25/2013
The install went without a hitch, (No pun intended). I liked the product for the 2013 Equinox and the fit was perfect. I would recommend you finish protecting the wire with either plastic spiral wrap or the plastic split wrap to protect the wire from wearing against any sharp edges under the vehicle. It is readily available from your big box hardware store. 86044
by: William J.10/31/2013
This was a small challenge. I did it myself and have very few tools. additionally at 75 with knee replacements I cannot get up and down very well, nor can I sit on my knees. (Butt only) Other than the minor adjustments normal for metal sizing once treated all went very well. Zero issues...."IF" you don't count some pain. Very well constructed product. 105845
by: Sam H.03/18/2012
Quick delivery. Clear instructions, good quality (good powder coating job). Easy to install (you don't need to move the tail pipe). Make sure weld nuts on the vehicle are cleaned out well before starting. A little grease to the bolts also makes them thread easier. Used with a trailer light kit. As always, very satisfied w/ etrailer.com products. 34262
by: Jim B04/20/2011
Received hitch and wiring harness very quick. It took me about an hour to install both. Th Curt Trailer Hitch Receiver and Wiring Harness were both quality products. I had reviewed the on line video for installing both and had no problem at all. My wife is extremely proud of both her new Chevy Equinox and her new trailer hitch. thanks 12072
by: Matt P07/08/2015
The wiring harness was very easy to install. Everything connected up perfectly and all the wires were the exact length needed. Removing the rear tail light assembly required a little work on my 2015 GMC Terrain....just be sure to pull straight back while wiggling up and down. Each assembly has two peg like tabs that pull straight out. 210133
by: Dale H.02/26/2012
Simple installation...I mean SIMPLE!!! The only suggestion that I could make would be to have some sort of mounting bracked for the trailer connector instead of letting it dangle loose. I know the instructions show the rubber cap keeping it in place, but that is still a little flimsy. Otherwise, very easy and took 15 mins to install. 32587
by: john w04/28/2011
Everything about e trailer is great. The web site is first class to start with. All the info is clear and very helpful. Video instruction is awesome and so is the price, free shipping and speed of delivery. Clearly you know how to please your customers. I will recommend etrailer.com highly. Oh ya the product was perfect too! Thank You! 12498
by: Tom W06/20/2015
I had about 35 minutes before I had to go help a friend so I decided to make sure that the receiver I brought from etrailer.com would fit my 2015 Equinox. I had no intention to install it at this time. After sliding the receiver in place I thought well I might as well but some bolts in. 20 minutes latter I had it installed. 205884
by: Jan O.07/23/2013
Installing the hitch and the wiring was amazingly simple thanks to the instructional videos posted on your website. My husband installed the hitch and I installed the wiring and we were finished quickly. PLUS everything worked exactly as it should! Thanks for saving us lots of money by showing us how to do it ourselves! 91087
Product worked well and was easy to install. I have not hooked the trailer up yet but the car lights are all working the way they did before the installation. I don't have any issues with the harness or the installation . It went well. Parts were delivered sooner that I expected and that is always a plus. 222654
by: Sorin Z.04/01/2015
The wiring harness came with detailed instructions via the video feed on the etrailer.com website. Very easy to follow and fits perfectly on our GMC Terrain. Very happy with customer support and all the follow up they do to make sure each customer is fully satisfied. Makes you proud that this is a US company! 182170
Both the hitch and the wiring harness were a breeze to install. Watched both install video's before attempting to the job and it made it very easy. Hitch looks great and wiring the harness with the T connectors made the electrical hookup a snap. Thanks for all the info (videos) that made this job simple. 68428
by: Indiana Dave04/14/2014
I received the towing hardware a few days earlier than I thought I might. I read the instructions a couple of times and had the hardware installed, by myself, within 30 minutes. It took me about the same amount of time to install the wiring harness. There were no surprises and I could not be happier. 124906
