Installation
This custom-fit T-One 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 you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse.
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.
Modulite Powered Tail Light Converter
A ModuLite power module is built into this T-One connector. Because your vehicle runs on a multiplex wiring system, the wiring needs to be converted to be compatible with the wiring system of your trailer. This power module functions as a tail light converter to combine the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.
With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring. Powered ModuLite reduces strain on wiring system.by: Gregory 03/16/2024
The instructions need to be clearer..such as the connection point is where the lights bulbs connect to the wiring harness is where the inline connector goes..thats why they say to remove the tail lights..otherwise, all went well… if I was to do this again,I I would go to U-Haul and let them do it..would be well worth it
by: Rick03/03/2024
Wiring harness worked well. Installation is relatively easy if you can follow directions. No issues in a year since installation.

ordered for a customer, as always, etrailer items are great and easy to install!
by: Matthew07/30/2022
Hitch is excellent, installation was straight forward quality is good. Purchased ball mount and ball to go with. Don’t forget the hitch pin like I did.
The lighting adapter kit was a bit of a disappointment. It works but installation was not easy on the Chevy Equinox. I was surprised to find that the controller requires 15 amps of power from a direct battery connection. I have installed trailer wiring on other vehicles that did not need battery power.
etrailer has good selection and pricing, shipping was fast and free. I recommend etrailer without reservation.

2021 Chevrolet Equinox
Super fast shipping, all parts arrived! The how to videos are spot on! Only thing I didn’t like is what’s in this pic, a bare spot on the molding process I reckon. I covered with tape and sealer. Cheers
by: Mark 02/28/2023
I probably sound like a broken record because all my reviews start the same. I ordered this and a trailer hitch to install on a friend of mines vehicle. Like always, the right stuff, the right price and on time. You help me keep my promises to friends and customers.
by: John06/04/2021
You will need a car lift to install the harness. You must raise and lower the vehicle at least 3 or 4 times. The last being to snake the power lead to the vehicle battery in a way so as not to pinch or burn it.I went to an auto electric shop to have it installed.

Made wiring much easier

2018 Chevrolet Equinox
Good quality and straight forward install. The one thing I would have changed is the length of the lead wire from the control box to the drivers side tail light patch connector. All the other harness sections have more than adequate length, but in order to get enough slack in the lead to the drivers side connection, I had to tear off and re-place the control box up higher on the body in an area that is not as flat and suitable to mount it. 2 or 3 more inches on that lead wire would have made it so the box mounts very nicely on the lower flat side of the rear body rail. All in all, a good product, just might need a tweak to fit the new Equinox perfectly
by: Artur O07/08/2020
Etrailer is a great company. Always my first choice for trailer parts.
I installed the wire harness using etrailer video guide without major issues. I used more tie wraps but that's just me.
After a year and a about 8000 miles with my trailer the harness works without any problem.
Vehicle is Chevy Equinox 2019 LT.
by: Bill08/25/2019
This is the 3rd order from etrailer and have never had a problem. The hitch was easy to install but you will need two people to hold the hitch in place while you put a couple bolts in place to secure it. I do not have a lift but using a jack and some stands will work just as well. My son and I were able to install it in just about 75 minutes. The online videos were perfect and document each step of the process. I also purchased a light kit as well but did not have the chance to install that yet. I will be doing that down the road and will let you know how I make out.

Chevrolet Equinox
Chevrolet used different electrical connectors on different configurations of the same vehicle, such as on the Equinox, they used different wiring connectors on the LS, LT and Premier and whether or not the vehicle was delivered with a hitch, or not, and some had a built in wiring connector for subsequent trailer wiring, or not, and diesel powered units may or may not. Obviously this is confusing and I ordered the wrong kit for my application. I have a diesel LT. etrailer communicated extremely well and we solved the problem quickly, exchanging the first kit with the correct one. Great people. I thank Carol and Odelia

The install of this wire harness went very smooth after watching the video. The step by step narration made wasneasy to follow. It took about 2 hours in my driveway. The materials provided are all good quality too.
I needed this wire harness to pull a trailer with the hitch that I got and installed from Etrailer a few years ago. I have been using the hitch for a bike rack which has been very handy and solid. Great products that are simple to install at home!
by: 77 year old customer11/16/2020
Installed the hitch on my 2020 LT1 Equinox. Easy install if you read the instructions and watch the video before you begin the install.

Great and works perfectly
by: Terrence shumaker08/23/2022
The electrical harness worked out pretty good except the yellow wire going up to the left rear tailgate could have been a little bit longer for my car (equinox)
by: Kenneth 10/21/2021
The only problem I had was not knowing that there’s two different harness for one type of car and I only found out after. I started running wire

Your vehicle determines which wiring harness you need. Because you have a 2019 Chevrolet Equinox without a factory tow package - Non Premier, then you ordered the correct harness. If you do have a premier with no factory tow package you would need item # 118759. If you do have a factory tow package then there are two options to choose from: item # 118285 or item # C94FR.

I was told by a hitch installer that the hitch I was looking for would not be available for 3-4 weeks. I found the hitch on etrailer.com. ln three days the hitch was on my porch, along with the wiring harness. Had it installed the next day. Very pleased with the service. The information shown on the site and the videos were very helpful. Will definitly be back and will recommend etrailer.com to my friends!

In the past I had always spliced-in the wires when installing wiring for a trailer hitch on a vehicle, but never again after seeing how simple this kit makes the job. With weather proof connectors that snap together, it will be much more reliable than the old splice method. And, it is impossible to wire it incorrectly, which could happen when you're looking for the right wire to splice into (or so I've heard).
by: Kenneth01/06/2022
I have actually had one installed since 2018 but due to an electrical problem in the trailer (short) it damaged the module. Thats good because it protected the cars electrical system from any damage. Once I replaced the module everything is working great again!
by: Rick H05/10/2020
Wiring harness fit my vehicle perfectly with simple plug in installation and performs as expected every time I need to tow a trailer.

The video with step-by-step instructions worked out perfectly with no hiccups everything was as described in the description before purchase and installing the hitch and wiring harness was very easy and done in a timely manner highly recommended!

Tyra F from etrailer personally called me to inform me I ordered the incorrect wiring harness and mount for my hitch I ordered for my SUV. She assisted me in ordering the correct parts and helped me figure out the best shipping option for my needs. Will definitely recommend etrailer based solely on their high level of customer service!!

view full answer... - Trailer Hitch Recommendation for 2018 Chevy EquinoxFor your 2018 Chevy Equinox the hitch I recommend is the Draw Tite part # 76217 if you have a diesel engine or the part # 76419 if you have a gas engine. These hitches have the best capacities for your vehicle and have a hidden crosstube which means they won't be as visible either. I attached install videos for both for you to check out as well. For trailer wiring you'd then want the part # 118750. This is our most reliable trailer wiring option we have for your vehicle.

- Trailer Wiring Harness For A 2019 Chevrolet EquinoxTo 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. This harness is also a plug and play and will plug into your vehicle's wiring harness, which is located behind the driver's-side and the passenger's-side...
view full answer... - Does Trailer Wiring for 2018 Chevy Equinox Need to Run to Vehicle BatteryNot all vehicles can handle the additional amperage draw of the trailer taillights on the vehicle taillight circuits. Those vehicles need setup that draws power from the battery. Some vehicles have higher rated circuits that can handle this, and others like your 2018 Chevy Equinox need to have the power drawn straight from the battery to protect the taillight circuits. We are aware that some people will ultimately run the power wire somewhere like you mentioned either out of ignorance...

Both of these tee into the connectors behind your tail lights and draw power via the black wire that gets routed to your vehicle battery. This helps to protect the wiring on your Equinox in the event that something goes wrong with your trailer wiring so that it doesn't backfeed to your Equinox. I...

The correct trailer wiring harness for your 2022 Chevy Equinox without the tow package will depend on which trim model it is. If your Equinox is the Premier model then you will need to go with the Tekonsha T-One Connector # 118759, and if it is any model other model then you will need the # 118750 instead. Now if you have not already decided on a trailer hitch receiver to go with this wiring then I recommend taking a look at the Curt Trailer...

The tongue weight capacity of the receiver is 675lbs and the maximum trailer weight capacity is 4,500lbs. Be sure to not exceed the weight capacities for your particular Equinox given from Chevrolet. The Receiver # C98CR is almost identical...

From my research, the factory towing package on your 2018 Chevrolet Equinox came with a transmission and engine oil cooler. Therefore, if you...

For your 2019 I recommend the Curt Trailer Hitch Receiver part # C98CR and if you need wiring the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118750. Both of these are custom made and confirmed to fit you 2019 Chevrolet Equinox.

- Trailer Wiring Recommendation for a 2022 Chevy EquinoxGlad to hear you're off on the right start with the Curt Trailer Hitch # C77FR on your 2022 Chevy Equinox! I'd be more than happy to help you navigate the wiring side of things. Smaller trailers usually only have a 4-Way connector for the basic lighting functions and for this I recommend the T-One # 118759 if you have the Premier model, the T-One # 118750 if you don't have the Premier model, or the Curt # C94FR if you have the factory Tow Package. Attached are some installation videos...

If your Equinox is not a Diesel model, I'd recommend the Curt Class III hitch part # C77FR. If it IS a Diesel, you'd want to use the Draw-Tite Class III, part # 76217. If you'll be towing with the hitch, you'll also need a trailer wiring harness like # 118759 if your vehicle is a Premier model, # 118750 if it isn't a Premier, and if it has the factory tow package, you'd use # C94FR which includes the relays needed...
view full answer... - Can Trailer Wiring of 2022 Chevy Equinox Work as Tow Bar WiringTrailer wiring can not be used as tow bar wiring as the converter does not allow the wiring to basically work in reverse. I wish it was the simple and convenient but tow bar wiring will have to be totally different from trailer wiring. What you'd want is a kit like the Roadmaster # RM-152-98146-7 which uses diodes to connect to your 2022 Chevy Equinox. I attached an install video for this kit on a similar 21' Equinox for you to check out as well.
view full answer... - Which Trailer Wiring Harness for 2020 Chevy EquinoxThe wiring harness you need will depend on whether or not you have the Premiers sub-model or not. For the Premier, you'd use # 118759 or # 118750 if it's not the Premier model. There's also a third less expensive possibility....if your Equinox has the factory tow package with the connector behind the bumper on the driver's side (see provided photo), you could use # C94FR. The # 118494 you'd looked at is for an earlier model Equinox, and wouldn't work on your 2020 model.
