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

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.

I thought the installation of the hitch was easy. The harness was even easier to install. Truly a plug-and-play operation. Remove the tail light, unplug the connector on the tail light. Plug in the trailer harness to the tail light. Plug the other connecter on the trailer harness to the vehicle harness. Pass the trailer harness down to the ground through a space in the fender. Replace the tail light. That side is done. I then ran the harness across the bottom of the vehicle and pulled it back up through the space in the fender using a piece of wire I had laying around and taping it to the harness. Then repeat the same procedure with the connectors as I did on the driver's side. Attached the ground using the self drilling screw provided and replace the tail light. The only problem I had was tie wrapping the harness to the vehicle to keep it up and away from any damage. The tie wraps that were provided were too small to go around the tube on the hitch. Perhaps, the design was to tie wrap it in another location but I though the tube of the hitch was the best location for me. I had some other tie wraps around and I used those. Overall the installation was very straight forward and well designed. Total time to install was about 30 minutes. 307814

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


Very satisfied with the products and service from already recommended your website to friends.Keep up the good work!All the best

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.

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


All is working fine. All lights work great, the trailer has never fallen off. I will buy another when i get a different vehicle.

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

The frame hitch(76028) arrived in good shape although it had worn through the box in 4 places. I was glad to see that 4 snaking wires were provided. I used them to position the 4 carriage bolts but left them on. With the hitch on the floor I threaded the wires into each frame hitch hole. Because I was working alone I raised the hitch on wood blacks. As I raised the hitch I made sure that each snaking wire stayed in the proper hitch hole. I did not remove the wires until the hitch was up against the car's frame. This way, It was possible to secure the hitch without danger of knocking the carriage bolts back into the car frame. The frame hitch fit nicely and I am completely Satisfied. The wiring (56094) went well but I do not like the wires being exposed to the weather, In the past i have carried the wires in the trunk and only exposed them to the weather when actually in use. 359802

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

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

The Curt Class III hitch I ordered from you was delivered in great shape, earlier than promised, and with all necessary parts. I did the installation myself on my 2015 Chev Equinox. It was a breeze with the help of your videos. I had to clean the dirt out from the threaded holes on the frame so that the bolts would be easier to tighten. Wiring for plug went smoothly. After removing two screws for taillight, it's important to pull the light assembly straight back and not rotate them or you'll risk damaging the plastic guide pins that hold the light assembly in place. I used a small wedge of wood to help coax them loose without scratching the paint. Thanks again for a great price and great customer support and follow-up. I will highly recommend to my friends or anyone needing your products. 417223

The hitch and wiring harness arrived on time. One of the vertical brackets on the hitch had broken through the box due to UPS manhandling, but nothing was damaged. After re-tapping the welded bolts on my 2012 Terrain the hitch was on in 15 minutes. Fit perfectly and looks like it came with the vehicle. The wiring harness was hands down the easiest product that I have ever installed on any vehicle. I like how nothing needed to be cut or spliced. Took me all of 10 minutes to install. And it works perfectly! I am very happy wit the product and service I received from etrailer. 372607

Great company to do business with. Web site easy to navigate, very informative. Can't say enough about all the great videos from choosing the right hitch to installing. Saved me a bunch of time. Went on easy using my motorcycle jack. I like the way the hitch sits high and out of site. Spend most time cleaning out the rusted threads on just a 2 year old car. Buy the wire brush if you don't have one. The wire harness was quick and easy. Sure beats the old days of finding wires and splicing into them. well worth the money. The hitch and harness was delivered in just a couple days. Will definitely be back as I rebuild my utility trailer. They have it all at great prices. Thank You ! 316462

by: Dennis SA08/05/2016 must be one of the best companies out there if not the best, both the trailer hitch and the wiring harness arrived before the expected delivery date. I forgot to order the harness when I ordered the hitch and at's own expense they sent the harness so that it arrived at nearly the same time as the hitch. This is my second order with this company and in both cases the goods arrived well packed and the quality of the goods is excellent, the fitting instructions were clear and concise, I had the hitch fitted to my Equinox and wired in just over an hour, it fits perfectly and the gadget to pull the bolts into the holed is incredible came with the kit. 280401

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

She was terrific, my product was shipped the same day and arrived after only 48 hours, just in time to use for our vacation. Installation took less than 15 minutes and we LOVE the product. The hitch is very high quality and was very easy to install. I just could not be more pleased with your company and your products. Erica was a life saver, she totally saved our vacation!

Trailer hitch and wiring harness are great quality and easy to install. I had a big problem and it had nothing to do with the parts from eTrailer. My GMC Terrain is about 3 years old and the threads that were in the frame for the bolts were extremely corroded. Getting them clean enough to get the bolts all the in was about a four hour job. If I had a proper brush and known about this condition I could have installed it much quicker. So my advice for anyone installing a trailer hitch in a vehicle other than new is to get the brush eTrailer offers and some penetrating oil. The videos on the website are very helpful too. 319744

This was my second trailer hitch from eTrailer. My first was for a Mercedes-Benz. This on-line order I purchased a Custom fit, Class III, 2" trailer hitch (Draw-Tite) for a GMC Terrain and a wiring harness for the trailer plug. I think the name "Draw-Tite speaks for itself. A very recognizable name. My brag is the service. I was well informed on the order progress. One day turn around on filling the order from "in stock"; prepaid frieght on UPS not on a slow boat from China. Both items shipped on January 3 from Missouri and were delivered in South Carolina on January 5 - mid afternoon. GREAT JOB!!!! 332992

The Curt T-connector installed easily. But was not the right harness for my vehicle, although it was the one recommended for my 2016 Equinox with no tow package. After using it for 4 kept blowing 2 fuses (1 for backup camera and 1 for dome lights) even though I had no trailer attached. I took it to the Chev. dealer, they checked everything out. After disconecting the trailer wiring the fuses didn't blow. So now I ordered the harness that has a module and a sparate power source as recommended by your tech. #118494. Haven't installed it yet, waiting for the weather to warmup! 348765

I installed a Curt hitch receiver on my new 2016 GMC Terrain. I then installed the wiring harness and it couldn't have been any easier. Took me about 20 minutes to install the harness. If all my projects were this easy, I would be a happy camper. Including photo of rear of the car with hitch. The harness connector is hidden up under the bumper cover so that it isn't just hanging down. 312776

Ordered the Trailer Jack and Curt T trailer harness. Trailer jack was exactly as advertised and bolted right on without any modifications. The wiring harness was an exact match for my 2013 Equinox and installed in about 15 minutes without cutting a single wire on the vehicle. I have installed a lot of trailer wiring harness on a variety of vehicles, this is the easiest one I have ever installed. My owner's manual advised against cutting and splicing wires as computer damage could occur. This harness plugged directly into the vehicle's taillights and could not have been easier. 301719

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.

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 4 flat t-connector was exactly as advertised. Its installation was straight forward and took about 30 minutes, only using a 10mm socket/wrench to remove the tail lamp assemblies. The tie wraps provided were too short to go around the trailer hitch, you need an 11" tie wrap. I bought a 4 flat connector bracket from Curt, but you also really need a Curt connector extension bracket and stainless steel worm screw clamp (sold as a package) to attach it to the trailer hitch. I modified the bracket to accept my own worm screw clamp. 269914

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

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

The hitch and wiring were a perfect fit for my vehicle. The folks at eTrailer make it look so easy and it really is. It took me about 1 1/2 hrs to complete the entire project, much of that time was due to the heat/humidity where I was working. This is my 2nd hitch from eTrailer and they make it easier all the time with the videos and visual aids on their website. They are my first choice as it is obvious they are serious of their products. Thanks for everything guys. 285596


Thanks for reaching out. The hitch works perfectly and everything is great. eTrailer is and will always be my preferred vendor for trailer related products. This was my 2nd hitch from you and you make installation so easy.

I bought the curt hitch and wiring harness for a gmc terrain. Both fit perfectly and where easy to install. a floor jack made a good second person with no back talk. I have installed at least a half dozen hitches over the years and this was the easiest one I have ever installed. the vehicle was well set up for it to start with but the pieces all fit well. Had to run the treads in the frame. other than that the hardest part was getting up after ward. getting old. 418207

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

  • 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...

  • Do I Need a Tow Package To Install 4-Way Trailer Wiring on 2012 Chevrolet Equinox
  • We do have wiring kits, that will work with your 2012 Chevrolet Equinox, that do not require the vehicle have a tow package. However, the item you selected, Tow Ready T-One Vehicle Wiring Harness, part # 118264, will only fit the 2010-2012 Equinox models that are equipped with the factory tow package. If your 2012 Chevrolet Equinox will not be equipped with a factory tow package, you could use either the Tow Ready Custom Fit Vehicle Wiring, # 118494, or the Curt Custom Fit Vehicle Wiring,...

  • 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...

  • The Curt T-Connector Vehicle Wiring Harness with 4 Pole Trailer Connector, # 56094, will fit your 2011 Chevy Equinox and will work to operate the trailer stop, turn, and tail lights. But, it does not have a circuit protected or powered converter to protect your vehicle wiring. If given the option, I will always recommend the circuit protected powered converter, # 118494, because it is designed to protect your vehicles sensitive wiring. What it does is virtually eliminate the extra power...

I recommend the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Connector, part # HM11141164. This harness simply plugs into the vehicle wiring located behind the tail lights on your Colorado. You will need to run the hot lead wire to the positive battery post to complete the installation.

  • Trailer Wiring Harness for 2014 Chevrolet Equinox Without Tow Package
  • Since your 2014 Chevrolet Equinox does not have any tow package wiring you'll start with a 4-pole harness like # 56094 which is a simple plug-in installation at the car's taillights. This provides stop, turn and tail light signals for the trailer. From there to convert to a 7-way RV-style trailer socket you'll need our # ETBC7 kit. This kit includes all of the components needed to convert the 4-pole flat plug to a 7-way socket like # 37185. An installation video and article are linked...

  • The Draw-Tite Class II 1-1/4 Inch Hitch, part # 36408, will fit a 2012 Chevrolet Equinox. It is the trailer hitch and pin and clip. To be able to tow with this hitch you will still need to purchase the recommended ball mount, 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 be the...

  • 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...

  • Advantage to Using the T-One 118494 with Powered Converter over Using the Curt 56094 Wiring Harness
  • The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, # 118494, allows you to operate trailer stop, turn, and tail lights but also includes a converter to protect your vehicle's wiring. This powered converter connects directly to your vehicle's battery to avoid overloading the electrical system. If there was ever a short or problem with the trailer's wiring, the only damage that could occur would be to the harness and not your vehicles wiring system. I am including a video...

  • 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...

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...

Sometimes there is another wire that will need to be run to the battery.

  • 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...

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...

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.

  • Hitch Recommendation for 2013 GMC Terrain
  • The biggest difference between the discontinued Hidden Hitch part # 87572, similar to the Draw-Tite # 76028, and the Curt Hitch part # 13591 that you referenced is the round tube vs. square tube. Another difference is that the Draw-Tite hitch uses a couple more attachment points. Either would work great for you. If it was me, I would probably go with the Draw-Tite based on the price difference. To complete your towing setup you may also be interested in the Curt Trailer Wiring Harness...

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....

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...
