Tekonsha Custom Fit Vehicle Wiring - 118759

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

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.

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.

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.

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.

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.

Review from a similar T-One in Custom Fit Vehicle Wiring


Product quality very high, delivery very fast, shipping container (cardboard box) was not strong enough to support handling/shipment, box bottom was ruptured with hitch assembly hanging out, box should be supported stronger, no parts missing, hitch was scratched up somebut, nothing that a little black paint didn't fix. I installed the wiring harness connections and fuse box on the external side of the vehicle to eliminate having to take apart the internal sheet metal panels and providing easy access to the fuse in the event of fuse failure, this eliminates the necessity of interior Panel removal to change a fuse. Easy installation, product has great great design features ,great customer service with prompt delivery. Just ordered the bracket (#18140) to secure the 4 prong plug to the hitch neatly and secure to eliminate the loose plug. (not shown in photos (Bracket in transit),

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.

    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...

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...

  • Which Trailer Wiring Harness for 2020 Chevy Equinox
    The wiring harness you meed 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 # 118285. The # 118494 you'd looked at is for an earlier model Equinox, and wouldn't work on your 2020 model.

Both options will provide you with a 4-Way connector to power a trailer's basic signal lights. If you still need a hitch I highly recommend the Curt # C77FR (as long...

  • Recommended Trailer Hitch and Trailer Wiring Harness for 2020 Chevy Equinox
    Given that you have a brand-new vehicle, I'm going to suggest you go with a hitch that's mostly concealed except for the receiver tube. I'd go with the Draw-Tite Class III hitch, part # 76419. This hitch is compatible with all models but the Diesel, so if you have a Diesel model, use the # 76217. The Curt # C13307 hitch you had looked at would certainly work, but the entire crossbar would be visible below the rear vehicle bumper, which some folks don't care for. I've edited a photo...
