  • Trailer Hitch Wiring
  • Curt
  • 4 Flat
  • No Converter

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 tail lights
    • Plug in T-connector
  • Comes with dust cap for 4-way flat connector
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle'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 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.

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

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

Works just like it says for 2014 Equinox. The hardest part about installing this kit was deciding where to put the ground wire. I used my 1/4" screw gun and drilled into the body with provided self taping crew just above the hitch. Hopefully our winters don't rust it out & require a new location.. 561003

  • Comparing Trailer Wiring Harnesses # 56094 and # 118494 for a 2011 Chevy Equinox
    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.

    The Curt T-Connector Vehicle Wiring Harness # 56094 is custom fit for your 2015 GMC Terrain and will work great. This will provide a 4-way flat trailer connector to power your trailer's signal lights once installed in the vehicle. I have provided instruction details and an installation video that you can watch to give you a better idea of the process for your vehicle. For towing purposes you will also need a trailer hitch ball and ball mount. I recommend a ball mount kit # 989900 because...

    The Curt T-Connector Vehicle Wiring Harness # 56094 referenced in your question can be installed in your vehicle that already has the tow bar wiring you mentioned installed, however they cannot be plugged in at the same time.

  • Trailer Lights do not Work with the Curt T-Connector Harness # 56094 on a 2013 Chevrolet Equinox
    According to Curt, the T-Connector Trailer Wiring Harness, # 56094, that you installed is compatible with your 2013 Chevrolet Equinox. 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...

  • Does the Computer have to be Reset to Install a Curt Trailer Wiring Harness on a 2012 GMC Terrain
    I went over the installation instructions and you will not have to have the computer reset when you install the Curt wiring harness, # 56094, on your 2012 GMC Terrain. 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.

  • Trailer Harness Wiring for 2012 Chevy Equinox
    If you do not have the factory tow package on your 2012 Chevy Equinox there is a harness that you can plug in behind the tail lights, the Curt T-Connector # 56094, which will give you a 4-way connector. If you instead needed a trailer end connector to plug into the harness on your Equinox you could use # H20046 for a 7-way or # A35W42B should you need a 4-way. I've added links to video reviews of each of these products for you to take a look at.

    If you tested the 4-way of the Curt Connector part # 56094 with a circuit tester like our part # PTW2993 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...

    You're correct that both the Curt # 56094 and the Tekonsha # 118494 wiring harnesses are fits for your 2013 Chevrolet Equinox. There are 2 (Actually there's more than just those two) because they're versions of the same product made by differenct companies. The harnesses serve the same purpose: to provide a 4-way trailer connector to power the trailer's lights. However, like you pointed out, they aren't identical. The Tekonsha has the powered converter which connects directly to the...

  • 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...

  • Wiring Harness Recommendation for a 2014 Chevy Equinox
    The Curt Wiring Harness part # 56094 that you referenced would work well on your 2014 Chevy Equinox. Like you noticed, it does not have a converter box or require a power wire run to the vehicle battery. I attached an install video for you to check out as well. For a hitch you also might be interested in the Curt Hitch part # 13591. For ball mounts I recommend the etrailer Ball Mount Kit # 989900. It comes with 2 ball mounts, 2 balls, a hitch pin with clip, and a carrying bag.

  • Can the Curt T-Connector Be Used To Bypass the Factory Trailer Wiring On a 2014 GMC Terrain
    Yes, the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 56094 will bypass the factory trailer wiring on your 2014 GMC Terrain. This harness draws signal from the tail lights and is then powered by the battery so it will be completely independent of the factory trailer wiring. It will also not cause any harm to the factory trailer wiring or factory tail light wiring either. The Curt T-Connector part # 56094 is a confirmed fit for your 2014 GMC Terrain.

  • Trailer Wiring Recommendation for 2011 Chevy Equinox
    You will need to start with a 4-way (if you do not have one). For that you would want the # 56094. Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire up the 7-way and install a brake controller. For a brake controller I would recommend the Prodigy P2 Brake...

  • Items Required for Towing Travel Trailer with 2013 Chevrolet Equinox
    The Equinox with the 2.4L engine does have a towing capacity of 1000-lbs, or 1500-lbs if the trailer has brakes. This is what GM says the vehicle can tow and you do not ever want to exceed the rated capacity for the vehicle. If the trailer you select does not have brakes then you need only a 4-pole wiring harness for the lights on the trailer. You can use Curt part # 56094 for the easiest plug-in installation, or if you want a harness that will protect the vehicle wiring from overloads...

  • 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 # RP74641, to keep your plug from dragging the ground. I also recommend...

  • Troubleshooting Left Turn Signal Not Working After Installing Curt T-Connector 4-Way Harness
    I first recommend using a circuit tester like # PTW2993 to test the left turn signal/brake light pin on the newly installed 4-Way. You can have a buddy activate the function in the vehicle while you test the pin for power. If you get appropriate power at this pin, then the issue is actually on the trailer side and you will want to turn your attention there. On the trailer, check its 4-Way for any corrosion or debris built up inside the pins, cleaning as needed. Make sure the main ground...
