Tekonsha Custom Fit Vehicle Wiring - 118759

  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • Powered Converter
  • Tekonsha

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.


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
    • Locate connection point behind tail lights
    • Plug in T-connector
    • Run hot lead to car battery
  • Includes ModuLite power module that connects directly to battery to avoid overloading vehicle's electrical system
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 5 amps per circuit
    • Tail lights: 7.5 amps per circuit
  • Limited 1-year warranty


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.


T-One Connection Location Points Behind Tail Lights

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 flat 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. 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.

This was the wrong part for my car. But I did not want to give it a poor rating because of that error. I am writing this review to prevent that error for others. BEFORE buying this, determine if your Equinox has the factory package. Watch this video and at about 2:20 minutes into it you will see a connector. Mine is identical to this, red tab and all. So now I have ordered the correct part which is C56375.

Product works perfectly. Installation was straight forward.



by:
Chevrolet Equinox

I purchased this as part of a package which included; Hitch and wiring for my 2022 Equinox, Base plate, Tow Bar, brake System and connecting air hose, break away cables, LED tow lights with wiring harness, and a trickle charger to keep the Equinox battery from going dead while I was towing it behind my class A RV.
I had etrailer do the install of all the components on my car and RV. All the workmanship was excellent and done in the amount of time they said it would take. Also because they did not have a video of this equipment being put on this year and model vehicle, I gave them permission to make a video(which added a extra day and a half to the install)and the installation was free. Everything has worked perfectly and I couldn't be happier. Etrailer is my go to for anything towing and also RV parts.

The tails going to the tail lights need to be 1” longer.
I had the converter mounted as close as it gets. One end or the other was short by 1”. A couple of heat shrink butt splices did the job.

2018 Chevrolet Equinox

The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector - #118759 for the 2018 Equinox Primer was a perfect match to the factory connectors. The directions were easy to follow and the kit included everything needed to complete the installation. When I bought this vehicle I knew I was going to install a trailer hitch w/wiring so I had the dealer install the 12 volt wire from the battery to the back of the vehicle for the power the module. This made the rest of the installation very easy.



by:

I actually got this kit just for the purpose of getting the splitter for the factory connectors so that I didn't have to cut into the factory wiring harness to add diodes and the lights for the SMI Stay n Play braking system. It worked out great. I can just remove the diodes from behind the brake lights if I ever want to return to the standard factory setup.



by:

Tolerance was poor and not aligned with some holes. The directions weren’t clear. Packaging and shipping it showed up in a mess and fell through the box.



by:
2018 Chevrolet Equinox

The kit is exactly right for the job with this car. I ended up buying some 3/8 rubber air line and fishtaping the hot wire through it to route under the car and through the non moving parts at the front and rear. I filled each end with silicone to seal it off and it really looks pretty good. Hopefully that'll protect it as long as I have the car. The only thing I'd add is the connectors behind the taillight leave little room for error. I felt like the driver's side went in a little too tight, I may take it back out to make sure it's in right. Overall I'd fully recommend this kit.



by:

Easy to install looks good great customer service video was extremely helpful with install they make it so easy to do



by:

Easy and fast ordering plus great instructions for specific vehicles.



by:

Simple to order. Fast to get delivered. Good installation instructions (that I could share with the mechanic who did the wrenching.) This is the second time I have used etrailer for hitches and I am very pleased.



by:

product was as stated a strong hitch and a plug and play wiring harness.



by:

Delivered in a short time. No fuss trying to finding the correct wires, just plug in connect to battery and ready to go. Hitch looks great just need to mount it.



by:
2019 Chevrolet Equinox

Thanks for the info. I will be working on the hitch and etc, sometime next week when the vehicle is available. I will let you know how everything goes. In the mean time, thanks for the great, speedy delivery.



by:

After a year harness works great. No p roblems.



by:

The customer support is great. They were proactive contacting me and helping change my order so that an out of stock item was replaced with a substitute so I could complete the installation without delay. The products fit and install as described. I recommend them for sure.



by:

multiple mistakes and broken promises, I’d give the whole order and etrailer a 2 overall for POOR service



by:
2019 Chevrolet Equinox

Fast shipping overall great service but the shipping box needs some firm foam. Our hitch came sticking out of the box.



by:

Everything looks in order for the wiring harness.

  • Which Trailer Wiring Harness For 2019 Chevrolet Equinox Without Factory Tow Package
    There are two trailer wiring harness for the 2019 Chevrolet Equinox without the factory tow package. You will need the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118750 as long as your Equinox is not the Premier model. If your Equinox is the Premier model you will need the # 118759 instead. I included installation videos for both of the harnesses mentioned for you to take a look at.

  • Determining Which Trailer Wiring Harness Is Correct For 2022 Chevrolet Equinox
    I would be happy to clear things up for you! 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...

  • Recommended Trailer Wiring Harness For a 2020 Chevy Equinox Premier
    Yes, there is a wiring harness option for the 2020 Chevy Equinox Premier. I recommend the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118759 which fits the premier model. The Tekonsha brand wiring is known to be more reliable than some of the other trailer wiring brands out there. If you plan on doing some towing you may consider the etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a...

  • Trailer Hitch for 2018 Chevy Equinox With Gas Engine
    There is a trailer hitch available for your 2018 Chevy Equinox but the Draw-Tite # 76217 will NOT fit unless you have a diesel engine. For your '18 Equinox I recommend checking out the Draw-Tite # 76419 which fits directly below your bumper; you can check out how it will look in the accompanying photo. This hitch will give you approximately 9 inches of clearance from the ground to the bottom of the receiver. For wiring which will give you a 4-way connector and allow you to power your...

  • Will Draw-Tite Trailer Hitch for 2021 Chevrolet Equinox Fit the Premier
    The Draw-Tite Max-Frame Trailer Hitch Receiver part # 76419 is a confirmed fit for a 2021 Chevrolet Equinox Premier. The Premier trim is not an issue for trailer hitch installation. It will however affect the trailer wiring which only matters if you're towing. The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118759 is the one you'll need for Premier trims.

  • Comparing Curt Trailer Hitch Receivers For a 2022 Chevrolet Equinox
    Of the 2 Curt receivers available for your 2022 Chevrolet Equinox, I recommend the Receiver # C77FR as the better choice. It has a class III, 2" receiver which has a lot more options available to fit when you are looking at hitch mounted accessories. 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...

    We do indeed have trailer hitches available for the 2020 Chevy Equinox. 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...

  • Trailer Wiring Recommendation for 2021 Chevy Equinox
    To add trailer wiring for your 2021 Chevy Equinox you'd want to start with the Tekonsha part # 118759 which provides the 4-way that covers the taillight circuits. Then you'll need to convert it to a 7-way since you want ability to charge a battery. For that you'd need the part # ETBC7L which comes with a 7-way adapter and everything needed to activate that circuit.

    There is a 1-1/4" Class II receiver that fits on the 2020 Chevy Equinox with the Draw-Tite # 36642. This hitch has the 1-1/4 receiver that you're looking for. If you're going to be towing anything with your Equinox you may need a few other items to complete your towing setup. If you don't already have a wiring harness for a 4 way trailer connection, you'll want to use the Tekonsha T-one # 118750 (for models excluding the Premier), which tees into your vehicle's electrical system with...

The hitch you referenced, part # 76419, is not a fit for a Diesel because it would interfere with the urea tank.

    The Draw-Tite Max-Frame # 76419 is an excellent trailer hitch for your 2019 Chevy Equinox!

  • Is there a Trailer Hitch for a 2018 Chevy Equinox that Fits in the Same Place as the Factory Hitch
    No, in this case the aftermarket hitches for the 2018 Chevy Equinox do not mirror the location of the factory hitch. Like you said the receiver on all the available options is below the rear fascia. The benefit though of an aftermarket hitch is that the hitch itself will be less than half the MSRP on the factory hitch and that does not include labor to have it installed if you choose to have the dealer install it. And the draw-back of the aftermarket hitches is limited ground clearance. If...

    I can certainly understand not wanting to run the hot lead all the way to the battery on your 2019 Chevy Equinox, and while most of the time it is necessary when installing the T-One Vehicle Wiring Harness # 118759, if you have an accessory 12 volt battery you can use that if it is a one-time use. However, you should not wire it to any other source in the vehicle that draws power - you should only do this if you have another, separate 12 volt battery that is not otherwise in use. I have...
