  • 4 Flat
  • No Converter
  • CURT

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle 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 rear bumper
    • Plug in T-connector
  • Comes with dust cap for 4-way flat connector

Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the center of the rear bumper.


Once installation is complete, the 4-way connector will be stowed beneath your vehicle, 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.

Well it was easy to plug in, but everyone said if you have the plug behind the bumper it will work.... Yes and NO. Guess my vehicle is the one that was not wired for running lights through that plug. 4 way, brake turn all work but no running lights.. There are no relays in the fuse box for those, and since I lease I'm NOT cutting and splicing into the vehicle.. 23 Chevy Equinox. Looking into Battery powered lights as an emergency if I get stuck in the dark sometime.. Maybe wire 2 taillights with a lawn tractor battery????

My 2020 GMC Terrain Denali without the trailering package already had the wiring under the bumper so this kit took less than 15 minutes to install.

2021 GMC Terrain

This was an exact fit for 2021 GMC Terrain Denali...even though the dealership said the vehicle was not equipped with the pre-wired trailer light inline plug...It was and this worked

Watched a video and installed the hitch and lights with no problems.

Great product and super easy to install following their video tutorial. etrailer is the only place to buy your towing accessories.



by:
2021 Chevrolet Equinox

This was by far the easiest thing I’ve done to my car just plug it in and done. Space was a little tight but it wasn’t the harness. Well worth the money I would have paid triple to keep from having the headache of running wires.

The Curt T-connector vehicle wiring harness with 4-pole flat trailer connector was a perfect match for my 2022 GMC Terrain. The harness plugged into the trailer wiring harness that was already present located behind the center of rear bumper. Thanks E-Trailer.

My dealer told me that GM would not sell me one for my Equinox because it was not designed for towing so I was pleasantly surprised at how easy the install was. Fits like a glove when following provided instructions.

As described

Not much to say.If your equinox has the factory plug you just plug this in,secure everything and your good to go.

  • Finding Install Harness for Curt Trailer Wiring for 2022 Chevy Equinox
    It sounds like maybe you found the wrong harness on your 2022 Chevy Equinox to install the Curt trailer wiring harness # C94FR. Best option I have would be to check out the install video I attached for this harness where you can see exactly where to find it.

  • How to Tell If a 2019 GMC Terrain Has a Factory Tow Package
    In order to figure out if your 2019 GMC Terrain has the factory tow package or not, you'll need to take a look in the rear fuse box on the driver side of your vehicle. In the fuse box there will be two locations you'll need to check - K2 and K3, which are for the trailer lights. These slots should be empty but what you need to be looking for is if there are wires are coming from the back of the K2 and K3 spots. If there are wires, then you have the factory tow package. If not, then...

  • Does Curt 4-Way that Fits 2019 GMC Terrain have Reverse Light Circuit
    4-way trailer wiring like what the # C94FR provides does not have the reverse light circuit as that's not a very common trailer lighting function needed. You would need to tap into the reverse light power circuit for what you are looking for.

  • Troubleshooting C94FR For 2018 Chevy Equinox
    The Curt Vehicle Wiring Harness for Factory Tow Package part # C94FR for the 2018 Chevy Equinox is the wiring for a Chevy Equinox with factory tow package so you do want to make sure that the Equinox has a factory tow package first. You also want to make sure you have the relays of the wiring harness in the k2 and k3 locations in the fuse box. If the relays are in the correct location, then you want to make sure the connector is seated fully with the wiring harness connector. Since the...

  • Troubleshooting Driver Side Turn Signal On Trailer Not Working After Installing Curt C94FR
    It sounds like a fuse is either blown or missing from your 2019 Chevrolet Equinox which is causing the driver side turn signal on your trailer to not work with the Curt Connector # C94FR installed. The fuse in question is fuse F18 which is the driver side turn signal for the trailer wiring. This fuse is in the fuse compartment in the rear of your vehicle on the driver side panel.

  • No Relays Found When Installing Curt Wiring for Factory Tow Package on 2019 GMC Terrain
    The Curt Vehicle Wiring Harness # C94FR that you referenced is supposed to be used if your 2019 GMC Terrain came with the factory tow package. If those fuse locations are empty, then it sounds like you don't have the factory tow package. As of August 2023, we do not have a wiring harness that will work for you. If your Terrain is supposed to have the tow package, then you should have metal contacts where those relays install. Since you don't, I'd reach out to your local GM dealer to see...

  • Do I Need Extra Fuses to Install the Curt Wiring Harness on a 2022 GMC Terrain?

Everything you need comes included with this wiring kit. You will be able to quickly and easily install a 4-way trailer connector on your 2022 GMC Terrain with this custom harness.

  • Troubleshooting No Power for Left Turn and Brake Lights for Trailer Connector on 2018 Chevy Equinox
    Since the issue you described is happening both with a trailer and with your magnetic tow lights I do think the culprit is a blown fuse or bad relay on the vehicle. I took a look at the online version of the owner's manual for your 2018 Chevy Equinox and there are a few different fuse panels so you want to make sure you are looking at the correct one. Inside the rear compartment fuse block, which is located behind the trim panel in the rear cargo area, there is a fuse in the F18 position...

  • What Does It Mean If I Can Hear The Relays Buzzing On My 2024 Chevrolet Equinox
    When relays buzz it usually means there is high amperage, which means that there is something not making a good contact. It could be caused by one of the wires that is cracked, so I'd recommend checking that. It's rare that relays go bad, but if the wiring and everything else looks fine then the best thing you could do is replace the harness with # C94FR.

  • How To Tell If a 2020 GMC Terrain Has the Factory Tow Package for Trailer Wiring
    In order to determine if a 2020 GMC Terrain has the factory tow package you will need to take a look in the rear fuse box on the driver side of the vehicle. In the fuse box there will be two locations you need to check, K2 and K3 which are for the trailer lights. These slots should be empty but what we are looking for is silver terminals inside each of the holes for the prongs on the relay. If there are silver terminals then you have the factory tow package but if not then you do not have...

  • Where Do the Trailer Wiring Harness Relays Install on a 2018 GMC Terrain
    For wiring harness # C94FR you may not need the relays if they are already present on your 2018 GMC Terrain. If the wiring harness works, then you can just hold on to them as spares. If it is not working, then they will need to be installed. Locate the fuse panel at the back of your Terrain. It is behind a little access plate on the driver's side. There are 3 relays for tow package wiring in this box. K1, K2, and K3. The relays will need to go in the K1 and K3 locations. The K2 spot is...

  • Tips To Disconnect The Tow Plug Connector On A 2018 GMC Terrain
    First, clean the connector # C94FR the best you can. Then you can go ahead and push them together as hard as you can. That will release some of the tension on the little tab. Then it may be a little easier to push in the tab and pull apart. If this doesn't work, repeat the process but you can use a hard edge like a flat head screwdriver or something to help get the tab to release.

  • Is There Separate Fuses On A 2020 Chevy Equinox For The Trailer Light Functions
    Yes, on most newer vehicles they do have separate fuses for the different light functions. On page 306 in your owners manual it shows what fuses are for what functions for your trailer lights. The fuse panel is located in the cargo area of the vehicle on the drivers side. It is most likely the fuse but if the fuse is not blown then the wiring harness may have malfunctioned which doesn't happen very often, but it could.

  • Curt Trailer Hitch Receiver For A 2024 Chevy Equinox

This hitch has a 675lb tongue weight capacity and 4,500lb gross towing weight capacity. You'll want to verify the capacities of your Equinox though so that you don't overload it. I've attached a short video below where John will walk you through the installation process. If you ever want to tow a small trailer or add lights to a cargo carrier or bike rack then you'll...

  • Recommended Trailer Hitch for a 2020 GMC Terrain
    The trailer hitch that I recommend for a 2020 GMC Terrain is the Draw-Tite Max-Frame Trailer Hitch Receiver part # 76419 because it has a hidden design which means you won't see the bulky, unsightly cross tube from the rear of the vehicle so you won't take away from its aesthetics. I have attached a photo of this clean look for you as well. In addition to aesthetics, the hidden design makes for the best ground clearance. If you will be towing a trailer then you'll also need a trailer wiring...

  • Trailer Wiring Harness For A 2019 Chevrolet Equinox
    To find out if your 2019 Chevrolet Equinox has a factory tow package or not you will need to look behind your rear bumper on the driver's side and see if there is a plug. If you have that plug you will need the Curt Wiring Harness # C94FR. If you do not have the factory tow package then you will need The T-One Vehicle Wiring Harness # 118750.

    If you do not have the factory tow package on your 2018 Chevrolet Equinox LT then the correct trailer wiring harness for you is the T-One Vehicle Wiring Harness part # 118750, not the Curt Wiring Harness part # C94FR. The Curt Vehicle Wiring Harness part # C94FR is only for model equipped with the factory tow package.

  • Trailer Hitch Recommendation for 2020 GMC Terrain
    You have chosen wisely because I highly recommend the Draw-Tite Trailer Hitch # 76419 for your 2020 GMC Terrain (non-diesel). The reason this is the best hitch for you is because it has the highest capacities at 4,500 lbs towing and 675 lbs tongue weight, which speaks to it's strength and durability, and because it is the only hitch rated for use with a weight distribution system, which is something people use regularly when towing. To add trailer wiring to power your trailer lights you...

  • Trailer Wiring for 2024 GMC Terrain that Doesn't have Tow Package
    Since your 2024 GMC Terrain doesn't have the factory tow package the only way to install trailer wiring will be with a universal style kit like the Curt # C59236 which does require splicing into the taillight harness of the vehicle. There isn't a no-splice kit that fits your vehicle configuration.
