Video Transcript for Curt T-Connector Vehicle Wiring Harness Installation - 2020 Chevrolet Equinox

Ryan: Hey everybody, Ryan here at etrailer. Today on our 2020 Chevrolet Equinox, we're going to be taking a look at and showing you how to install a CURT custom-fit trailer wiring. So this wiring is going to provide us with the signals that we need to be safe and legal whenever we're pulling a trailer. And for those of you that have light up, hitch-mounted accessories, like some cargo carriers, for example, this is going to allow them to work properly as well. Now, what I really like about this setup is the fact that it utilizes the inaudible 00:00:33 factory tow package plug. So the manufacturer pretty much did all the work for us.

This one is just going to plug in and work like it should.Now I do want to mention not every single Equinox is going to have that plug, but it's really easy to find out. The connector is located right here in this area behind your bumper, so you can just take a peek up there and see if that plug is there to use. So wiring's really important whenever you're pulling a trailer, knowing that all of them signals are working properly, it's going to make you feel a little bit more safe as you're driving down the road. So this wiring is going to be mounted outside. I'm using a couple brackets to set it up like this.

These don't come included, but if you need some, you can find them here at etrailer. And since it is permanently mounted outside, it's going to be really easy to get to and you use whenever you do need it. And what's important is that this kit is really well-built. Everything feels heavy duty and it should last you a long time. It's going to have a little rubber dust cap here that helps keep the terminals protected underneath it.Now, I do recommend to go a step further and from time to time, just supply a little bit of dielectric grease to those terminals, and that'll help ensure that you don't have to worry about any corrosion issues down the road.

But at the end of the day, a really super easy and reliable way to get us those trailer signals that we need. Now since this essentially does is plug right in, as far as installation goes, it's not going to take you hardly any time at all. To begin our install, we're first going to need to locate our factory connector. It should be located behind our bumper right here in this area. So now here behind our bumper, what we're going to do to make it a little easier to gain access to her plug is remove this one bolt here, that's holding on the bottom of her fascia, take a seven millimeter socket and pull that out.

We should be able to pull down on her fascia a little bit, so if we look right up here, we're able to see that factory plug.Now it is going to have this little dummy cap on it. So we'll need to remove that and to do that, we'll push down on that red tab, and then push down here in the center, that tab. And We'll be able to remove that dummy plug. Now we can take our new wiring harness, and this end here, it's going to line up with that factory connector so we can raise this up into position, line it up, plug it right in, once it's connected, don't forget to push down on the red tab. That's like a locking device to make sure that it won't accidentally become disconnect. Now that we have it plugged in, what I'll go ahead and do is secure our wiring and route our four pole connector over where we're going to mount it. So I'll go ahead and do that now and show you how I did it.So I secured our wiring up here in this area, and I just used some of the included zip ties to do that. And our four pole connector, I just routed right over here through our hitch where we have it mounted. Once you have that done, go ahead and take that screw and just re-install it to secure your fascia. Something I want to mention, is that the kit does not come included with any brackets, so if you want it to be set up something like this, that is something you have to pick up separately, and you can find many different types of brackets here at etrailer.Now, it is a good idea to test our wiring, to make sure it's working properly. So we'll go ahead and turn on our running lights, we'll hit our brakes, we'll try our left turn, and our right turn, and that'll finish up our look-at and our installation of the CURT custom fit trailer wiring on our 2020 Chevrolet Equinox.

if you have the towing wire harness in your car , this is the way to go one plug and your done , better to put this in before you install the the trailer hitch

- C94FR

Easiest installation ever,it only took a few minutes . I put the hitch on last week which was also a breeze, very happy with my purchases, Highly recommend these products

2020 Chevrolet Equinox

Plugged into the factory connector and worked perfectly. I didn’t have the relays in the back fuse panel on my 2020 equinox (but it did have the connector under the bumper for the lighting) so the built-in relays on the harness are helpful.

The order and shipping were exactly what I ordered. The instructions that came with the hitch and wiring were very helpful. I tried to do as much as I could without a lift. Getting the bolts through the correct holes with the provided wires took quite a while. I had to take the hitch to a car repair place I use to get it installed. There is no way I could do it without a lift. The instructions said 40 minutes. It took the car replace place an hour and a half and that was with a lift. This is beyond the hour and a half I spent on the installation. All I need to do now is to hook the trailer up.

Easy install

My hitch and wiring harness installed with ease! Can track shipping, great quality!

A simple plug and play. You unplug the vehicles protective cap and plug in the supplied plug. It takes more time to wire tie the wires and relays in place. Well built design.

Ask the Experts about this Curt Custom Fit Vehicle Wiring

  • Correct Trailer Wiring Harness for 2020 Chevy Equinox
    If your 2020 Chevy Equinox is equipped with the factory tow package, the correct Curt harness is the T-Connector # C94FR. If you don't have the tow package (there isn't a factory connector already present at the bumper) you will instead want the Tekonsha T-One Harness # 118759, which plugs in-line behind the tail lights. Both options will provide you with a 4-Way connector to power a trailer's basic signal lights. If you still need a hitch I highly recommend the Curt # C77FR (as long...

  • Are Extra Relays or Fuses Needed to Use Curt Trailer Wiring Harness on 2020 GMC Terrain
    I can understand how the wording could be confusing on whether or not the Curt # C94FR (56429) will work on your 2020 GMC Terrain, but I can confirm that it will indeed work for you without needing to install any extra fuses or relays on the vehicle. The "with tow pacakge" selection on our site, refers to having the factory harness behind center of the rear bumper, like you mentioned having. According to my contact at Curt, this is present on all 2020 GMC Terrains, which is why they...
