Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located along your rear bumper. Once you've plugged in the connector, open your fuse box and locate the fuse position indicated in the instructions. Then insert the included relays.

The only difficult thing to installing this harness is getting the cap off of the car's wiring harness. After sliding the red lock tab out, make sure you push on the black tab in front of the red sliding tab while pulling the cap off. Trust me. Without pushing on the black tab, the cap won't come off. Once that's off just plug in the new harness and route it to the area where the safety chains attach.

Great. Using it today as a matter of fact. Makes wiring up for a trailer a breeze.

Very good plan-n-play harness, but the plug? Only issue was the male pin came out of the plug after only a couple of uses. Had to splice a cord and plug on the fly as we were taking a trailer with us on a trip, so no time to return, warranty etc. Overall a nice product, but now I have a spliced cord, which isn't desirable.

This OEM tow package wiring connector is fairly priced, arrived within the timeframe indicated, well packaged, and ready to use. Following etrailer's online video instructions I easily installed and tested this item and it works perfectly.

I have never installed a hitch before and am 79 years old. I followed your videos of the install of the hitch and the wire harness. everything went well and no problems at all. It took me about 2 hrs. thanks for the great design to fit my vehicle.

Good simple product, but I returned it because my vehicle did not have the towing harness and fuses blocks from the factory.

Excellent product... I have a 2018 Chevy Equinox and this wiring harness along with the light tester worked great. The video by etrailer.com made it very easy to understand.This is the 1st time I attempted this type of wiring When I made the connection and then tested the lights and everything worked.... it was a big relief. Thanks

Fit perfect with my 2019 Chevy Equinox. The only issue I found was with the relays. They don't fit very tight into the plug, and they don't snap into place. I ended up having to zip tie them in to make sure they stay in place. I added some wire conduit around the wires and then double wrapped electrical tape around the length to protect it.



- C56375

The trailer wire harness (curt) instructions tell you to install relays... The relays are not needed and the only place that it says that they "May" be needed is in the install video that is only listed under the equinox, not under the Terrain install only took one-two min. I just wish the install sheet was more clear!

Bought this to fit my 2019 Chev Equinox. Cheaper here than anywhere. Installed easy and worked like a charm. Much better than splicing into wires. I bought the vehicle end tester which made testing so much easier. I am on the east coast of Canada and would recommend etrailer to anyone.

Simple and easy to install! Instructions could have been more specific for connector location (i.e. - under vehicle between bumper beam and body). Also supplied relays fit very loosely and required twisting the terminals slightly to get them to stay in contact.

This was ordered and shipped same day. it was sent via snail mail but still got it in about 3 days. I would definitely recommend etrailer parts because they are exact fit - plug and play. Easy!

Works great on my 2018 gmc terrain diesel. The relays were not necessary for my vehicle. Very simple plug and play easiest wiring job I have done. Plenty of wire so you can have plug where ever it needs to be. Very pleased. Thank you.

Ask the Experts about this Curt Custom Fit Vehicle Wiring

  • Does Curt Trailer Wiring C56375 Plug Directly Into 2018 Chevy Equinox
    Yes, the Curt trailer wiring harness part # C56375 that you referenced comes with everything that allows you to easily install a trailer wiring harness in your 2018 Chevy Equinox. It's a simple wiring connection and a few relays. I attached an install video for this kit for you to check out as well.

  • Are Relays Needed When Installing Curt Wiring Harness for 2018 Chevy Equinox with Tow Package
    The relays that are included with the Curt T-Connector Vehicle Wiring Harness # C56375 for your 2018 Chevy Equinox may or may not be needed. On some Equinox models with the tow package, the slots are available for the included relays, but there is actually a factory relay already present nearby. In these cases, the additional relays are not needed. Since you do not see any wiring running from those slots, you likely have the factory relay so you simply don't need to install these.

    The correct custom trailer wiring harness for your 2018 Chevy Equinox without the factory tow package is the Tekonsha # 118750.

    If you do not have a towing package you will not have the locations for the relays in the fuse box that come with the Curt T-connector wiring harness part # C56375 or the Tekonsha wiring harness part # 118285 because they are designed for the 2018 GMC Terrain with factory tow package. If you do not have the factory tow package you need the wiring harness with the converter box and in-line fuse holder part # 118764. Without the in-line fuse and converter box the wiring harness could potentially...

  • Trailer Wiring for 2018 Chevy Equinox Premier
    There are wiring options for your 2018 Chevy Equinox Premier. If you have the factory tow package you would be able to use either the Curt # C56375 or Tekonsha T-One Wiring Harness # 118285. If you did not have the factory tow package you would want to use the Tekonsha T-One Wiring Harness # 118759. Both of the Tekonsha options are without photos, as you mentioned, but their links can still be found below. If you are going to be towing, I recommend checking out Ball Mount Kit # 989900,...

  • Troubleshooting Trailer Left Stop/Turn Lights Not Working with Curt # C56375 on a 2018 GMC Terrain
    It sounds like you probably have a short on your left stop/turn circuit on your trailer end. It is very unlikely that the wiring on your 2018 GMC Terrain is messed up as it is a brand new vehicle so I would start by checking the connector on your trailer for corrosion or debris. If you have any fuses or relays on your Terrain dedicated to the trailer lights then they would be worth looking at as well. If that looks good then check the wiring and grounds on that circuit. Look for places...

  • What is the Purpose of Relays Included with the Curt T-Connector # C56375 for 2018 Chevy Equinox
    Sometimes a vehicle, like your 2018 Chevrolet Equinox, will come with the factory tow package but for some reason will not include relays. The relays included with the Curt T-Connector # C56375 that you purchased are intended to be used to activate the lighting functions. If relays are already installed then you can save them in case one of your relays ends up needing to be replaced in the future.

  • Troubleshooting Trailer Left Turn Signal Not Working on 2019 Chevy Equinox
    According to Curt the # C56375 wiring harness is a fit for your 2019 Chevy Equinox LT. If it wasn't you probably wouldn't even have a compatible connector to plug it into in the first place. Since it's just the one function and it's definitely on the vehicle side I'd start by checking the relay you installed. Cavity K3 holds the Left trailer stoplamp/Turn signal lamp relay so make sure it's seated properly. If it seems to be then switch the relays between cavities K2 and K3 and then...

  • Troubleshooting Trailer Lights not Working With 2018 Chevy Equinox
    I was unable to find the order number of the wiring harness you ordered from us so I'm not sure exactly what you have but if just the driver side doesn't work it is probably not an overload; there are a number of troubleshooting steps you will need to take. The first thing to do is take a look at your owner's manual to locate any trailer fuses or relays and ensure they are all there and in working order. Check the wiring going into your harness from your tail lights to see if those wires...

    The Curt T-Connector Vehicle Wiring Harness # C56375 referenced in your question is confirmed to fit your 2018 Chevy Equinox as long as it has the factory tow package. Some models of the Equinox do already have the needed factory relay for the signal lights and in these cases the included relays simply aren't needed. It sounds like this is the case on your vehicle. I am not aware of any programming that needs to be done on your Equinox in order to account for the power draw of trailer...

  • Trailer Left Side Lights Not Working with Trailer Wiring C56375 Installed in 2018 Chevy Equinox
    It sounds like there is a problem with a relay on the vehicle side. In the fuse panel located in the rear of your 2018 Chevy Equinox check to make sure there is a relay in the K3 location. Wiring harness # C56375 comes with 2 relays and one of them goes in that K3 location. It is for the left side trailer brake light and turn signal. It is a good idea to check any and all fuses/relays related to the tow package wiring. Under the hood that would be location F28. In the cab check location...
