Video Transcript for Trailer Wiring Harness Installation - 2017 Chevrolet Equinox

Today in our 2017 Chevrolet Equinox we'll be installing the Curt T-Connector Vehicle Wiring Harness for a factory tow package. This will give us a four pole flat trailer connector. Part number C56210. Now here's what our wiring looks like installed. As you can see, we can mount it on the outside of the vehicle. Now this wiring is our typical four pole flat trailer connector. This will allow us to have all of our required by law in order to safely tow our trailer.

We'll have our turn signals, our brakes lights, and our tail lights and then whatever running lights that are on the trailer as well. Now we'll begin our installation by opening our hatch. We'll take off our spare tire cover here and set it aside. Now on the driver's side of our vehicle, right down here, you can see a gray connector. We grab this connector. This is our factory tow package connector right here.

We'll take the end of our new wiring harness, plug it in until it clicks and you can see it's secure. This wiring harness is typically designed to be stored inside the vehicle and when you need it, you can drape it down out here to the side of your hatch latch. Close your hatch on up and you can hook up to your trailer down here. When you're not using it, you can store it underneath your spare tire cover. Our customer today requested to have this on the outside of his vehicle, so we'll route this to the outside through a grommet. Right here there's a grommet.

We grab it and we can pull it up. We pushed the grommet through the bottom once we had it pulled out, so we can have better access to make a notch in it for our wires to pass through. Just use a pair of side cutters here to snip through this. Okay, now we can push it back on up and we'll reinstall it from the top. Okay, we'll grab our four pole flat trailer connector here.

I'll push it through that hole. Okay, with our wire pushed through, we'll push our grommet back down in position so it's secure around our hole. Okay, snap back in all the way now. Okay, with our connection made we can now put our hatch cover back in. Close our hatch on up and go underneath and seal up our grommet with the silicone now. Got some on my finger here, just smear it in that crack. This will keep any moisture, dirt, or debris from entering our vehicle or exhaust fumes. We don't want any of that coming inside. Once that's sealed up we can move on to the next step. Now we can take our included dust cover, slide it over our wiring here. We'll bring our wire on up here and we'll secure it to our safe chain loop here on our hitch. Close the dust cover up around it. This way our wiring is readily accessible when we need it. We'll secure the rest of our wire up here with a couple of zip ties, so it's up out of the way. There's already an existing hole here in the body. We can use this as a place to tie down to. Trim off our excess zip ties. Now we can test our wiring before we hook up to our trailer. We're using part number I26 for this tester if you'd like to purchase one. All right, we'll start by turning our headlights on and as you can see, our tail light functions for our trailer to be working. Use the left turn signal. Right's working as well. Now I'll step on the breaks. As you can see, all of our functions are working. That completes our installation of the Curt T-Connector Vehicle Wiring Harness for a factory tow package. This will give us a four pole flat trailer connector. Part number C56210 on our 2017 Chevrolet Equinox.

Just installed the MaxxTow (MT70033) Trailer Hitch on my 2016 GMC Terrain. It was a perfect fit and was easy to install (as shown on the video). Great for any DIY. I didn't have a lift so I just jacked the back of the vehicle up a little bit. The only problem I had was getting the wire fish tape (was a little to limber and it kept folding up in the bumper) thru the bumper so we took a long wire tie and but thru first, then taped the wire fish and pulled it thru. Everything else went together just as described! I would recommend this product to any do it yourselfer to save on installation cost. 614850

Very easy installation on my 17 Chevy Equinox. I appreciate the installation video I was able to check out before I ordered. It came with the plug that simply snapped in place behind the left tail light accessed from the trunk area with no disassembly required. I chose keep the trailer plugin inside with the spare tire. Very easy to get to whenever I want to hook up to my 5 X 8 utility trailer' 653108

This wiring was just the thing I needed and the install was easy. I have used my trailer several times, the latest was yesterday, and everything was just fine. I would recommend using e-trailer for all your needs as did I because they even have videos that a beginner like me can follow and that make installation very, very clear and easy to do.... Thanks for allowing me to write something positive for this product and for your company. 546280

Again, etrailer's video made this install a piece of cake. Easily located the prewired connector back by the spare tire. After a couple of moments figuring out what angle I should twist my hand to get the tow package harness plugged into the prewired connector. Once I figured that out the connector easily popped together. I stored the extra wire around the spare tire. At this time, I did not thread the wire through one of the grommets for an exterior fit. Maybe later if I find I'm using a wired trailer. 519809

Plugged right in on my 2014 Terrain and works. I didn't even have to take that panel off. Awesome. All I need to do now is find a proper grommet to run it permanently to the hitch so I don't have to close the hatch on it. 488857

It was simple to put together. The only hiccup was when the box arrived the bag holding the hardware had opened and there was a hole in the box and 3 nuts were missing. Easy fix, went to local hardware store and purchased what was needed to complete. Haven't used it yet but looking forward to. Seems very sturdy. 482389

I just wanted to tell you that I installed my Draw Tite, Trailer Hitch and the Curt Custom Fit Wiring on my 2012 Equinox ans it was a Breeze ! Everything went smoothly and it was so easy to do. Having the pre-threded holes already on my vehicle etc. and the video tutorial you provided on your web site, made the job fun, easy and frustration free! Thanks for caring such such a great product and having such an easy web site to navigate. I have already recommended your site to several people , including my brother-in-law so I expect you will be hearing from them very soon. Jim 462953

I am 74 years old and installed this in less than 5 minutes during a spitting raw rain storm with temps near 40 degrees. Yes, you can do it and so much more professional than a cobbled and spliced together mess. 447445

Plugged directly in to my 2015 Equinox LS. There was a few post about this will fight if you have the tow package. My Equinox is the 4 cylinder. The plug was there so I think it is in place for all models after 2015. No need to pull the panels to access. Just lift up your spare tire cover & look over towards the drivers side fender. Plugged it right in - 2 minute job! 385540

Great Company to do Business with. I ordered a Trailer Hitch and wiring from eTrailer. I put in the order online, on Friday and received my Hitch on Monday. Everything was neatly packaged, and in order. The Hitch was a fit for my car and was of good quality. My sales person was named Pat. She knew exactly what I wanted, and was extremely helpful. She was also a very nice person to do business with. This Hitch was less expensive, than anywhere on the Internet. Great people, less expensive, no problems. Thanks Pat, for making this buy, a pleasant one. Thanks etrailer, for the low price. Jack A. 339325

Ordered Curt Trailer Hitch part number 13591 and Curt T-Connector wiring harness part number 56210 for 2016 Equinox and it arrived 10/5/16, day before Matthew went up coast of Florida. Shipment arrived quickly and in good condition. I installed the wiring harness right away and it took longer to open the tail gate and remove spare tire cover than to install the harness connector. 305639

Do you have a question about this Custom Fit Vehicle Wiring?


  • Correct Trailer Wiring Harness and Other Parts Needed to Tow a Trailer with a 2015 GMC Terrain
  • Both the Curt # C56210 and the Tekonsha # 118264 fit your 2015 GMC Terrain as long as you have the tow package. The connectors are designed with a slightly different clip but they both work the same and mate with the same connector. Since you've already found the connector behind the driver's side trim panel in the rear cargo area your Terrain has the tow package. The other parts you'll need to tow with your GMC, if you don't already have them, are a trailer hitch receiver, ball mount,...

  • Which Trailer Wiring Harness Fits 2016 Chevy Equinox
  • For the 2016 Chevy Equinox the correct 4-way harness is the part # 118264 or Curt part # C56210. These will attach to the factory trailer wiring port in the rear of the vehicle. I attached pictures that show you where to find the port at the rear of your vehicle. The T-harnesses you mentioned should still work but since they are not designed for your vehicle variation I can't recommend them.

  • 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...

All you need to do is enter the part number # RHK into the search box on our site, then enter your hitch number 76028 and select the manufacturer from the drop-down menu box. I have linked an installation video for this hitch in a 2013 Terrain as well as two articles that will provide useful tips for hitch installation. If...

  • How to Tell if 2015 Chevrolet Equinox Has Factory Tow Package
  • If your 2015 Chevrolet Equinox has a factory tow package, there should be a trailer connector at the rear of the vehicle, behind the rear bumper. The connector could also be inside a black box that is mounted under the vehicle. If this is present, then your Equinox almost definitely has a factory tow package. Another way to be sure is to simply take your VIN number to a local Chevrolet dealer and they will be able to tell you exactly what was installed in the factory for your vehicle.

  • Recommended Trailer Hitch and Wiring for a 2017 Chevrolet Equinox
  • The trailer hitch size that allows you to use the widest variety of accessories would be a 2 inch hitch like the Draw-Tite Class III Max-Frame Trailer Hitch Receiver # 76028. This hitch is a confirmed fit for your 2017 Chevrolet Equinox and will enable you to choose from a bigger selection of bike racks, cargo carriers and other accessories.

The easiest way is to simply keep it stored inside under the removeable floor and then it out the back hatch to your trailer when you need to use it. As long as you keep it to the left or right of the middle latch (see attached picture) then the door will...

I recommend the Lets Go Aero LED Light Kit # H01540 because it comes with easy to use surface mounting brackets and has a 72" wiring harness, which will be enough for you to plug into the Curt Wiring Harness # C56210 that you mentioned you have on your '16 Equinox.

  • Troubleshooting No Brake Lights from 2016 GMC Terrain Wiring Harness
  • The first thing to check is that your harness connectors are fully seated together. Also it can happen that one of the metal contacts in the connectors (either the vehicle or harness side) could be bent and this could prevent the brake light signal from reaching your trailer. Also check the main ground wire for the Terrain's wiring harness; this white ground wire must make metal-to-metal contact with the vehicle. You can try cleaning/sanding the grounding point, moving the ground wire...
