Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector - 2012 Terrain by GMC

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.


  • Provides a 4-way flat trailer connector at the back of your GMC Terrain to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection points behind tail lights
    • Plug in T-connector
  • Comes with dust cap for 4-way flat connector
  • Made in the USA
  • Limited 1-year warranty


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.

Video Transcript for Curt Custom Fit Vehicle Wiring 56094 Review

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. .

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 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


Still impressed with the installation and the good fit. I have hauled various stuff in my 6 by 6 trailer, up to about 2500 lbs. Works fine. Doesnt feel loose. Doesnt squeak. Had several compliments on the look and subsequent referrals.

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


Almost a year ago, I bought and self-installed the trailer hitch and wiring harness. The hitch and wiring harness have worked flawlessly since then. I have hooked up a bike rack to the hitch and traveled without fear. I pull a small utility trailer and the lights and hitch have not let me down. Thanks.

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 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

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

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 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

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

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

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

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

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

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

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

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

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

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/ products. 34262

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

Couldn't of been an easier install, had it done within 15 minutes. Watched the videos on the website and everything laid out as suspected. Only thing I'd recommend is longer zip ties as they were not able to go around the hitch frame but I made them work through existing holes in the bumper rail. 178901

by: Pat L09/09/2013

Excellent video instructions - installed as described without issues. Hint: Before you route the passenger side wire bundle back up into the tail light assembly, make sure you have routed the wiring package and connectors in/around the hitch assembly through the openings and holes that you desire. 99137

We have several different trailer hitch options for your 2012 Equinox, so I attached a link to all of them for you to check out. The trailer hitch that I recommend is the Curt Class III Trailer Hitch, # 13591. This hitch will save you some money over the Draw-Tite and Hidden Hitch Class III trailer hitches without sacrificing any...

  • Recommended Trailer Wiring Harness for a 2014 Chevy Equinox
  • For your 2014 Chevy Equinox, the vehicle wiring harness I recommend is # 118494. The converter is a nice feature because it will reduce strain on your wiring system as it connects directly to your battery. If there was ever a short in the wiring, it will only blow the converter or a fuse vs. if you had the wiring harness # 56094, a short could cause additional problems to your vehicle. A converter isn't required but it's definitely a worthwhile investment. I highly recommend using dielectric...

  • What are the Differences Between Trailer Wiring Options for a 2012 Chevrolet Equinox
  • The Curt wiring harness, # 56094 and the Tow Ready harness # 118264, are for different variations of a 2012 Chevy Equinox. Tow Ready harness # 118264 is designed for vehicles that have a factory tow package. Curt harness # 56094 is for a vehicle that does not have the factory tow package. You are correct in that the Curt harness would receive power through the vehicle wiring to the trailer lights. Any problem could affect the vehicle electrical system. Another option is to use the...

  • Hitch Recommendation for a 2015 Chevy Equinox
  • The Curt Hitch part # 13591 that you referenced is the correct hitch for your 2015 Chevy Equinox. Check out the install video I attached. For trailer wiring you would want the Curt Wiring Harness part # 56094. For ball mounts I recommend the etrailer Ball Mount Kit # 989900. It comes with 2 ball mounts, 2 balls, a hitch pin with clip, and a carrying bag.

  • Does Hidden Hitch # 90145 Include Everything Needed To Tow a Trailer With 2012 Chevy Equinox
  • The Hidden Hitch Class II 1-1/4 Inch Hitch, part # 90145, will fit a 2012 Chevrolet Equinox. It is the trailer hitch and includes the ball mount and pin and clip. To be able to tow with this hitch you will still need to purchase the hitch ball and the wiring harness for lighting the trailer lights. I am including links to the installation instructions and a install video of the hitch being installed on a 2010 Equinox (same on the 2012 model). The wiring harness for your Equinox would...

  • Trailer Wiring Recommendation for a 2010 Chevrolet Equinox, Circuit Protected vs Unprotected
  • We stock both the Tow Ready Custom Fit Vehicle Wiring, # 118494, and the Curt Custom Fit Vehicle Wiring, # 56094, because we have customers that request both styles. Many times customers do not want to run the extra wire to the vehicle battery, so they order the # 56094 harness. The Battery connection is the biggest advantage of the # 118494 harness for protecting the vehicle circuitry. I would use the circuit protected model, # 118494, because there is always a possibility of a short...

  • Does the T-Connector Wiring Harness Violate the Warranty on 2010 Chevy Equinox
  • The T-Connector Wiring Harness for the 2010 Chevy Equinox, part # 56094, is very easy to install. You will simply plug it into the factory connectors behind your tail lights and you will be ready to tow. Installing a wiring harness will not interfere with your warranty. I would recommend two things. If you will be towing frequently, I suggest a mounting bracket like the 4 and 5-flat Trailer Connector Mounting Box, part # 18145, to keep your plug from dragging the ground. I also recommend...

  • Will Trailer Wiring Harness 118264 Fit a 2014 Chevy Equinox without Factory Tow Package
  • If your 2014 Chevy Equinox did not come with the factory tow package then the factory connection point is probably not functional. You can test it with a circuit tester such as # 3808 while someone runs through the lighting functions on the vehicle. If it is functional then you can use harness # 118264. If it turns out not to be functional then you will need either harness # 56094 or # 118494. I recommend the powered harness # 118494 because the direct connection to the battery is sued...

  • Does the Computer have to be Reset to Install a Curt Trailer Wiring Harness on a 2012 GMC Terrain
  • I went over the installation instructions and you will not have to have the computer reset when you install the Curt wiring harness, # 56094, on your 2012 GMC Terrain. If you are apprehensive about it, you could always disconnect the negative battery cable prior to installing the harness. You will use any programmed information, like stereo presets, but that is easy enough to reset.

  • Does the BCM Need to be Reprogrammed to Install a Trailer Connector Harness on a 2010 Chevy Equinox
  • I spoke with my contacts at Curt and Tow Ready, who both make wiring harnesses for the 2010 Chevy Equinox. They stated you will NOT have to reprogram the BCM or anything else to install the Curt T-Connector, # 56094, or T-One with Upgraded Circuit Protected Modulite, # 118494. I recommend the T-One with Upgraded Circuit Protected Modulite, # 118494, as it has a powered Modulite that will help protect your vehicles sensitive wiring. I have included a link to the installation details below....

  • Hitch Recommendation for 2013 GMC Terrain
  • The biggest difference between the Hidden Hitch part # 87572 and the Curt Hitch part # 13591 that you referenced is the round tube vs. square tube. Another difference is that the Hidden Hitch uses a couple more attachment points. Other than that it looks like the Curt costs a little less. Either would work great for you. If it was me, I would probably go with the Curt based on the price difference. To complete your towing setup you may also be interested in the Curt Trailer Wiring Harness...

  • Trailer Lights do not Work with the Curt T-Connector Harness # 56094 on a 2013 Chevrolet Equinox
  • According to Curt, the T-Connector Trailer Wiring Harness, # 56094, that you installed is compatible with your 2013 Chevrolet Equinox. It sounds like there may be an issue with the wiring harness itself since your trailer lights work with another vehicle. The first step I recommend taking is to inspect the connections for the wiring harness and make sure it is grounded properly. If you see any pinched, frayed or damaged wires, the harness could be shorting out, which would explain why...

If you plan on doing 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 the ball mount kit does not...

  • Is Dealer Programming Needed to Activate Tow Package Wiring in 2014 Chevrolet Equinox
  • The Curt T-Connector Vehicle Wiring Harness # C56210 that you referenced is intended for the Chevrolet Equinox that has the factory tow package. The connection point for this harness is behind the driver-side rear trim panel. The only thing you may need to do to activate this harness is install the required tow package fuses and/or relays IF they are not already in place. Check the power distribution box under the hood for any empty fuse holder location labeled 'trailer' or 'tow'. If...

  • Difference Between Wiring Harnesses For 2011 GMC Terrain With No Tow Package
  • The Tow Ready Custom Fit Vehicle Wiring, part # 118494 has a powered converter that helps protect the vehicle wiring circuit and will supply enough power for the trailer wiring if needed. The Curt Custom Fit Vehicle Wiring, part # 56094 would be a good choice if you have LED lights on your trailer or if you do not have a lot of lights. I recommend the # 118494 because it does help prevent any damage to the vehicle wiring and would make sure you have sufficient power to the wiring...

  • 7-Way and Brake Controller Recommendation for a 2014 GMC Terrain
  • Since you do not have a factory trailer wiring you will need to start with a 4-way (if you do not have one). For that you would want the # 56094. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well. This also will give you a 12 volt accessory power circuit. For...

  • Troubleshooting No Power on the 4-Way Curt Harness part # 56094 on a 2008 Chevy Equinox
  • If you tested the 4-way of the Curt Connector part # 56094 with a circuit tester like our part # 3808 and got no power out of any of the pins with the different taillight function applied the first thing I would do is make sure you grounded the white wire of the harness to a clean metal surface that touches the vehicle frame. The next thing I would do is make sure that all of the connectors are securely in place. You could even unplug them and then replug them back in. I attached an...

  • Can Trailer Hitch and Trailer Wiring Harness from 2014 Chevy Equinox Be Moved to 2014 Model
  • The hitch and wiring used on your 2012 Equinox can indeed be reused on your 2014 model. Both vehicles use the same hitches and wiring. However, the installation hardware for the hitch is not meant to be reused and should be replaced. To obtain replacement hardware, go to the the # RHK product page by using the link provided below. Type in the hitch part # C12291, select the name of the hitch manufacturer from the drop-down menu, and choose a quantity of 1. I'll link you to some install...

  • I went out into our warehouse to measure a Universal LED Tailgate Fire Strip Brake, Tail, Turn and Reverse Light # 360438 that we had in stock and found that the main portion of the strip is 11/16 inches in width, but if you count the mounting pads as well the thickness ends up being 7/8 of an inch. This strip comes with a 4-way that would be able to connect to a harness like the part # 56094 that you would have installed on your 2012 Chevy Equinox

  • Curt Trailer Hitch Fit and Related Items Needed for 2015 Chevrolet Equinox for Towing Small Trailer
  • The base version of the 2015 Chevrolet Equinox has a maximum rated towing capacity of 1500-lbs but you'll want to check your actual owner's manual to confirm the towing capacity for your particular Equinox since this can vary depending on the version and specific equipment included. You are wise to go for a 2-inch Class III hitch as these not only offer higher capacity (and safety margin) but they're also more compatible with a range of hitch-mount accessories like bike and cargo carriers....
