Tekonsha Custom Fit Vehicle Wiring - 118682

  • 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 points behind tail lights
    • Plug in T-connector
    • Run hot lead to car battery

  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 4.2 amps per circuit
    • Tail lights: 7.5 amps per circuit
  • 1-Year limited 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 and some interior paneling to access this harness. Once you've plugged in the connector, run the red hot lead up to your car battery. Connect the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


T-One Connection Location Points Behind Tail Lights

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. 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.

2016 Lincoln MKX

My son & I were able to install the hitch and wiring harness in about 3 hours. The videos to install gave me the confidence I needed to do the job correctly and safely. Good job! Due to the bumper fascia of the 2016 Lincoln MKX, I did not want to fasten the mounting bracket for the 4-pole connecter on the fascia itself. So I ordered the no-drill long bracket (#18136) and bent the strait end 90° to form a shape of a long [. I was then able to attach the long bracket on the hitch and bolt the mounting bracket on the other end of the long bracket. The 4-pole connecter is now just below the bumper facial and easy to get at. Very clean look and sturdy!

Installation was easy. Hitch has worked fine for the first year. I was worried that the "kick-to-open" feature would not work on my Lincoln MKX after the hitch was installed, but it still works just fine. A word of caution: When working with the hitch (changing balls, mounts, connecting wiring , safety chains, etc.), locate your key fob someplace away from the vehicle because the rear door will open and close unexpectedly if you keep the fob on your person.

Ask the Experts about this Tekonsha Custom Fit Vehicle Wiring

  • Does Tekonsha Trailer Wiring Kit # 118682 fit 2019 Lincoln Nautilus
    We do have several options that will work on your 2019 Lincoln Nautilus, but you are correct when saying part # 118682 will not fit the 2019 Lincoln Nautilus. Currently we do not have any wiring harnesses that plug in behind the taillights for this vehicle, so you will be required to either hard wire in behind the tail lights or go with a zero contact interface (ZCI) style wiring kit. The first option is a Curt # C59236 . This is a universal wiring harness that fits your vehicle and...

  • Comparison of Draw-Tite Hitch Receiver vs Curt Hitch Receiver on 2018 Lincoln MKX
    Either the Draw-Tite Hitch Receiver # 75234 or the Curt Hitch Receiver # C78KR would be a great addition for you 2018 Lincoln MKX. I recommend the Curt Hitch Receiver # C78KR as it offers the same maximum Tongue Weight (TW) rating at 675lbs, and Gross Trailer Weight (GTW) rating of 4500lbs. In my experience the powder coat finish the Curt uses is more durable and less likely to chip or scratch, and the Curt Hitch Receiver # C78KR is also made in the USA. Make sure to review your owners...

  • Trailer Hitch Recommendation for 2018 Lincoln MKX
    For your 2018 Lincoln MKX the best hitch option is the Draw Tite part # 75234 as it has the best weight capacities and the best price. For trailer wiring you'd then want the part # 118682 which is a confirmed fit. Install video attached below. If you wanted to do some towing you might be interested in 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 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball,...

  • Curt Hitch on a 2018 Lincoln MKX
    I'm happy to inform you that the Curt Hitch, part # C78KR, does indeed fit with your 2018 Lincoln MKX. This hitch is custom designed for the MKX line and features a simple installation process. It's a Class III hitch and can handle up to 4500 pounds of gross trailer weight and 675 pounds of tongue weight, so you will be able to haul a variety of accessories. If you're looking to use a trailer with this hitch, then I recommend the T-One Vehicle Wiring Harness, part # 118682, for wiring....

  • Will Hands Free Liftgate Still Function With Install of Draw Tite Hitch on 2017 Lincoln Continental
    Your hands free liftgate function on your 2017 Lincoln Continental will still work with the install of a hitch like the Draw Tite part # 36596 that you referenced. At worst you might have to kick your foot to either side of the hitch opening but it will still work just fine. If you were in need of trailer wiring as well the Tekonsha kit part # 118682 is the best option as it installs very easily and also has the most reliable converter box of the kits we offer.

  • How To Choose The Right Ball Mount For 2017 Lincoln MKX With Draw-Tite Trailer Hitch
    The Draw-Tite Maxx-Frame Trailer Hitch # 75234 is a good fit for your 2017 MKX. This is a Class lll hitch and it has a 2-inch receiver opening. You do want to tow the trailer as level as possible. I have attached a link to an installation video for this hitch on an MKX. As shown in the video, the distance from the ground to the top of the hitch opening is 12-1/4 inches. This is done when the vehicle is parked on a level surface. You can get a good idea what ball mount will work...

  • Will Trailer Hitch from Buick Enclave Fit Lincoln MKX
    The Draw-Tite Class III # 75528 and the Curt Class III Trailer Hitch # 13424, which are the available trailer hitches confirmed to fit the 2014 Buick Enclave, are compatible with certain model years of the GMC Acadia, Saturn Outlook and the Chevy Traverse. However, the trailer hitch on your Buick Enclave will not fit your new Lincoln MKX, as the body styles are simply too different between the vehicle models. If you are able to tell me the year of your Lincoln MKX, I will be happy to...
