Tekonsha Custom Fit Vehicle Wiring - 118567

  • Custom Fit
  • Trailer Hitch Wiring
  • Tekonsha
  • 4 Flat
  • 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.


  • 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


  • Maximum amperage:
    • Stop/turn lights: 2.1 amps per circuit
    • Tail lights: 5.6 amps per circuit
  • 1-Year limited warranty


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.

Fit well and easy to install. I only wish they had included better quality butt splices, I substituted some of my own with heat shrink on them to better seal the wire from moisture and corrosion. Overall good product. 130398

  • Trailer Wiring Harness for a 2017 Dodge Journey Crossroads with LED Tail Lights
    We do have trailer wiring harnesses that plug in line with the tail lights on your 2017 Dodge Journey. But they also require power from the vehicle battery. The reason is that the vehicle wiring cannot handle the additional power draw from trailer lights. With power coming from the vehicle battery that problem is eliminated. And it also adds another level of circuit protection between the trailer and vehicle. You can use wiring harness # 118536 for your 2017 Journey with LED tail lights....

  • 4-Pole Trailer Wiring Harness for 2017 Dodge Journey with LED and Incandescent Tail Lights
    Trailer wiring harnesses are not usually included with a hitch since not all trailers have lights. The typical small utility trailer that one might use to get a load of mulch will often not have lights (or trailer brakes, for that matter). But we can certainly help you with a 4-pole wiring harness for basic trailer lighting functions if you will be towing a trailer with lights. On your 2017 Dodge Journey the choice of wiring harness depends on the type of tail lights the car has....

  • Which Trailer Wiring Harness w/ 4-Pole Trailer Connector for 2015 Dodge Journey w/ LED Taillights
    For 2015 Dodge Journey models with LED taillights, you'll want to use the Tow Ready # 118536. The Tow Ready # 118567 you referenced is for models with incandescent taillights, so it will not work on your vehicle. If you click the provided link, you can see an installation video. I've also linked you to a listing of other vehicle specific items and accessories for your Dodge Journey.

    For your 2016 Dodge Journey with incandescent taillights the correct trailer wiring harness is the part # 118567 which I attached an install video for. If instead you had LED taillights you would have wanted the part # 118536.

  • Hitch Recommendation for 2017 Dodge Journey AWD
    Your 2017 Dodge Journey is one of the vehicles for which two types of hitch are made, both a smaller 1-1/4-inch Class II hitch and a 2-inch Class III. In such cases we always recommend the 2-inch option since it will be compatible with more hitch-mount accessories and because it will offer a higher weight rating without much more additional cost. The Class III hitch I recommend for your Journey AWD is the etrailer # e98845 because it will offer easier installation than others and because...

  • How to Tell if 2018 Dodge Journey Has LED or Incandescent Tail Lights
    The easiest way to determine if you have LED or incandescent lights on your Dodge Journey is to simply watch them illuminate and turn off. If they come on immediately and turn off immediately then they are most likely LEDs. LEDs will also be quite a bit brighter and almost painful to look at directly. If instead you can see a bit of a transition both when coming on and turning off and the light is a bit duller, you have incandescent bulbs. If you are still unsure I recommend simply...

  • Recommended Trailer Hitch for 2018 Dodge Journey AWD
    We actually have a somewhat large selection of trailer hitches that are confirmed to fit your 2018 Dodge Journey with the AWD. I specifically recommend the Draw-Tite Max-Frame Trailer Hitch Receiver # 76225 because of its hidden design and superior ground clearance. This Class III hitch features a drop-down 2" receiver that allows the crosstube to stay completely hidden behind the bumper. This not only creates a clean, factory-like appearance but it also keeps the receiver further...

  • Towing Capacity and Recommended Trailer Hitch for 2018 Dodge Journey
    I took a look at the online owner's manual for your 2018 Dodge Journey. If you have the 2.4L engine you can tow a trailer that weighs up to 1,000 pounds. If you have the larger 3.6L engine the maximum trailer weight is 2,500 pounds (with 1 to 2 people in the vehicle). This capacity drops with more passengers (2,000 pound capacity with 3 to 4 people and 1,500 pounds with 5 to 7 people). I do recommend also verifying this information in your copy of the manual or by checking with your...

  • Towing Capacity of 2017 Dodge Journey and Parts Needed to Pull 1,900 Pound Trailer
    I tracked down an online version of the owner's manual for your 2017 Dodge Journey and if it's equipped with the 3.6L V6 engine it listed a towing capacity of up to 2,500 pounds. This max capacity is assuming there is only 1 to 2 persons in the vehicle. As the inhabitants grow the capacity decreases as follows: 3 to 4 persons - 2,000 pound towing capacity 5 to 7 persons - 1,500 pound towing capacity With this in mind your Dodge Journey is capable of towing a 1,900 pound trailer as...

  • Trailer Wiring Harness for a 2013 Dodge Journey that Will Work with a Trailer that has LED Lights
    For the trailer wiring harnesses for the 2013 Dodge Journey the indications in our fit guide that specify with or without LED lights pertain to the vehicle tail lights. So if your Journey has LED lights you can use # 118536. If it does not have LED lights use # 118567. Both wiring harnesses are compatible with trailers that have LED or regular incandescent lights. I have linked videos on both harnesses for you.

    Although I don't know if your 2018 Dodge Journey already have wiring for the light functions on a trailer, I can let you know how to find that out and offer some solutions for if you don't. To figure out if your Journey has wiring you simply need to check the back of your vehicle and see if there is a 4-Way flat connector that looks like the picture I attached for you. You may also want to check inside the hatch of your Journey as well. If you cannot find a connector then that means...

  • Recommended Parts to Tow a Trailer with a 2015 Dodge Journey
    Certainly. I recommend the Draw-Tite trailer hitch receiver, part # 76225. I like that once it's installed you only see the open receiver tube and not the crossbeam. It is a more difficult install and requires you to cut some fascia on your 2015 Dodge Journey. I've linked the video from when we installed it along with the install details for you. If you prefer an eaier install then look at the Curt # C13201. To install the Curt you need to temporarily remove the spare tire and lower...

  • Determine if 2014 Dodge Journey has LED or Incandescent Taillights for Trailer Hitch and Wiring
    Easiest way to tell is to watch the lights illuminate. If they come on immediately with basically zero transition between off and on and are almost painful to look at you have LEDs. If you can watch the bulb get brighter and looking at the light doesn't hurt your eyes you would have incandescents. Also if the bulb is round and has that old school style of wiring in it where there is two vertical wires and a couple horizontal wires that run between them that is incandescent. For a...

We have Class ll and Class lll trailer hitches. This hitch is a Class ll hitch but as you mentioned you need a 1-1/4 inch receiver opening, so this would be the hitch you want.

    According to the vehicle owner's manual the 2016 Dodge Journey with the 2.4 liter 4 cylinder motor has a maximum gross trailer weight capacity of 1,000 pounds and tongue weight capacity of 100 pounds. Based on this you would not be able to tow a 1,700 pound trailer.

    The trailer hitch that is both the most hidden and has the best ground clearance for your 2014 Dodge Journey is the Draw-Tite Trailer Hitch Receiver # 76225. The reason for this is because it has a fully concealed crosstube and installing it requires cutting the fascia, as you can see by the accompanying photo.
