Tekonsha Custom Fit Vehicle Wiring - 118803

  • Trailer Hitch Wiring
  • 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.

  • 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
  • Includes ModuLite to ensure that your vehicle's wiring matches that of your trailer
    • Powered module 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
  • 1-Year limited 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. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are 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.

The hitch and wiring kit were delivered on time and in good condition. All the parts fit on my vehicle perfectly. The hitch is built of very heavy steel and is capable of handling heavier loads then my Lincoln Nautilus can haul.
That's a good thing. The paint finish was thick and durable and fully covered all of the hitch.
I'm totally satisfied with everything E Hitch supplied.

Easy to order, on time delivery, great pricing, huge inventory, nice follow up. They got it right

Installed in 2019 Lincoln Nautilus. Took about 1.5 hrs to install. Taillight removal and wire routing can be a problem, not just plug and play. Depending on how much work you want to do you could wind up taking off the back bumper skin and wheel well trim. There is a 12v outlet in the left rear panel you could use for power.

The wiring harness for my new Lincoln Nautilus worked as advertised and I am totally pleased. Timely delivery. A prior harness from etrailor required cutting and splicing that would void the warrantees and etrailer took it back with full refund.

I installed it on my 2019 Lincoln Nautilus and it was tough finding room for the parts (no extra space in taillight openings). It works well and is worth the time spent installing. I'm satisfied.

Ordering was easy, the parts fit well and shipping was on time.

  • Most Hidden Trailer Hitch Recommendation for 2020 Lincoln Nautilus
    The Draw Tite hitch part # 75234 is the most hidden trailer hitch for your 2020 Lincoln Nautilus. Only the hitch opening hangs below the rear bumper which will give you a mostly hidden look and will also help with ground clearance. I attached a picture that shows what it looks like installed as well. The picture is of a Ford Edge which is the same platform as your Nautilus. I also attached an install video link too. For trailer wiring the best option is the Tekonsha kit part # 118803 which...

  • Recommended Hitch and Wiring For 2020 Lincoln Nautilus Black Label
    I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver part # 75234 for the 2020 Lincoln Nautilus Black Label. It will fit all models of the Nautilus and is a concealed cross tube design. The only portion of the hitch that is visible on the vehicle once installed is the receiver tube. If you need wiring, I recommend T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118803 which is a custom fit wiring harness so there is no splicing involved.

  • Best Trailer Hitch Receiver for 2020 Lincoln Nautilus
    The best trailer hitch I highly recommend for your 2020 Lincoln Nautilus is the Curt Trailer Hitch Receiver # C78KR. This is the best hitch for your Lincoln because it has a concealed crosstube, is a bolt-on installation that will not require drilling into your vehicle's frame to install, and is made in the USA. This Class III, 2" trailer hitch is almost entirely hidden behind your bumper, as you can see by the accompanying photo. The hitch has a black powder coat finish to protect it...

  • What Is The Most Hidden Trailer Hitch For A 2020 Lincoln Nautilus?
    For your 2020 Lincoln Nautilus there is two trailer hitch options, the Draw-Tite # 75234 and the Curt # C78KR. Both of these have the exact same hidden crosstube design so both will be equally as hidden, and both have the same 675lb tongue weight rating and 4500lb trailer weight rating. There is however one key difference, the Curt # C78KR is made here in the USA where the Draw-Tite hitch is not. Due to that difference, and the powder coat finish on the Curt hitches being a bit tougher...
