Tekonsha Custom Fit Vehicle Wiring - 118715

  • 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.


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
    • Connect 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: 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 in your rear cargo area.


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.

My son and grandson installed the items I purchased and they have performed without fail during this past year. I am quite pleased. Having a lot of life experience there is nothing more discouraging than having to fix something almost every time it is used. That is not the case with your products. I have become so accustomed to their performance that I seldom think about them and that is good! 633994

I have 2014 & 2017 Escapes. I put this trailer lighting kit on both. It installed perfectly on both vehicles. The design is well thought out. It took me a 2-1/2 hour to do the first one. A few months later it took me about 1 hour to do the second one. 454336

My new Draw Tite hitch fit perfectly, you really need four hands when installing.. it would be a much easier install if yo have access to a car lift as it is a tight fit.. The wiring and installation of hitch went exactly as videos showed.. I wanted to protect back of vehicle in parking lots and that was one of the reasons for putting hitch on this car. Pictures attached. Thank you for your service 501518

2017 Ford Escape

Installed trailer hitch and wiring harness on a 2017 Ford Escape with some minor issues. The trailer packaging on delivery was a little lean and the corners had the paint scraped off. I called in to etrailer and they agreed to credit me the cost of a can of paint which I would need anyway. This happened within minutes of my call! I install it myself with no help and without jacking up my car! Installed one rear side 1st (passenger side) and then the two bolts on the driver side and then back to the front bolts on the passenger side. Two issue I had with the install: 1. The trailer was about 0.5" too narrow so I tapped with a mallet and expanded enough to install 2. One wire guide for the bolts broke on the last bolt. It would be a good idea to provide some extra wire with the install kit! I have to fish out the bolt and washer and create a replacement wire. I used bracelet type wire for this. Also an auto flexible magnet tool from an auto parts store with used for this purpose of fishing out the bolt and washer. Beside these two issues the hitch install without other problems and I did this alone. Also install a wiring harness and your provided videos on the wire harness and hitch were the best I have seen for an installation guide. I did buy and use black paint and black silicone sealant as per your videos. 619686

To date the unit has had minimal use but has performed as designed. Installation in the 2018 Escape was complicated not because of the unit itself but the design of the vehicle. There was plenty of room in the underfloor area for the unit, but getting the wiring to the taillight assembles required removal of interior trim panels. It also took extra effort and a pull tape to get the power wire to the car battery. This installation took nearly two hours. 766306

  • Trailer Wiring and Hitch Recommendation for 2018 Ford Escape
    Since your 2018 Ford Escape does not have trailer wiring or a hitch that would essentially mean you do not have the tow package so for trailer wiring you'd want the T-One part # 118715 because it's the most reliable option we offer for your truck and it doesn't require any splicing. I attached an install video for more info as well. For a hitch I recommend the etrailer hitch part # E98866 because it has a 2 inch opening, great towing capacities, and has a hidden crosstube which makes...

  • Recommended Trailer Wiring Harness for 2018 Ford Escape
    I recommend part # 118715 for trailer wiring on your 2018 Ford Escape. It has a higher amp draw than the other option. It plugs in behind each tail light and then there's a wire that needs to be connected to the Escape's battery. Everything you need for the instal is included. I've actually linked a video from when we installed it. I've also linked the video of us installing the etrailer.com htich, part # E98866, in a 2017 Escape. The process is the same with your 2018.

  • Can Trailer Wiring Harness Power Wire Be Connected To 12V Circuit In Rear Cargo Area Of 2017 Escape
    When installing a trailer wiring harness like part # 118715 or # C56320 on your 2017 Escape, the Black power wire needs to be run to the positive battery post. A lot of folks want to use a circuit near the back of the vehicle instead of running the wire all the way to the battery. We recommend installing it as per the installation instructions. If you connect to a different circuit, you would not be aware if a fuse blew or if something happened to the circuit, which would mean you have...

  • Running Power Wire of Tekonsha Trailer Wiring Harness in 2017 Ford Escape
    When installing the wiring harness # 118715 in your 2017 Ford Escape the power wire should be ran directly to the battery. It's protected by the included fuse. There's no need to install a switch because your Escape's tail lights will function normally with the harness installed. The power wire powers the harness to keep the trailer lights from drawing all their power directly from the tail lights. The 4-way will still receive power when not towing which is normal.

  • Recommended Trailer Wiring Harness for a 2018 Ford Escape Without Factory Tow Package
    For your 2018 Ford Escape without factory tow package I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118715 because Tekonsha has a better reputation with customers for their wiring harnesses over the competition. This harness will simply plug into the factory wiring connections behind your tail lights. Once installed you then will run the included power wire up to the battery. I've attached an installation video to assist as well as an article to help...

  • Which is Easier, Routing Power Wire Under Carpet or Under the Vehicle for Trailer Wiring
    On a new vehicle it's going to be much easier to run the power wire for trailer wiring like the part # 118715 outside of the vehicle as opposed to pulling up the carpet and then trying to get it through the firewall. I attached a help article that covers the options for routing the power wire of a trailer wiring harness for you to check out as well.

  • Does Power Wire of Trailer Wiring for 2018 Ford Escape Have to Run to Vehicle Battery
    Not all vehicles can handle the additional amperage draw of the trailer taillights on the vehicle taillight circuits. Those vehicles need setup that draws power from the battery. Some vehicles have higher rated circuits that can handle this, and others need to have the power drawn straight from the battery to protect the taillight circuits. Even if the circuit you have at the rear fuse box is more than capable for the trailer wiring harness part # 118715 bypassing it and running the battery...

    The best trailer wiring harness for your 2018 Ford Escape is the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118715 because of its simple installation and the fact that it is rated for the most amps among the harnesses available for your Escape.

  • Right Turn Signal Activates Both Turn Signals on Trailer with 2017 Ford Escape
    I first recommend disconnecting the trailer and using a circuit tester like # PTW2993 to test the functions on the 4-way connector from the Tekonsha T-One Vehicle Wiring Harness # 118715 you installed on y our 2017 Ford Escape. Test to make sure all of the proper functions are being activated. I have included a helpful video that will walk you through how to test a converter. Then check to make sure that there is no corrosion or debris inside both the vehicle and trailer side connectors....

  • Running Power Wire for 4-Way Trailer Wiring on a 2018 Ford Escape
    I don't recommend connecting the power wire of the # 118715 to anywhere but the vehicle battery. Using the 12 volt outlet in the cargo area of your 2018 Ford Escape may not work properly. The converter needs to receive power from an isolated 12 volt circut and you really don't know if that circuit is isolated or not. There could very well be other components running off the same circuit. If it's not an isolated circuit you could be blowing fuses over and over again. I've linked...

    A powered 4-pole wiring harness like the Tekonsha # 118715, which fits your 2017 Ford Escape that does not have the tow package, will not pull significant current from your vehicle battery/alternator unless the harness is connected to a trailer. When connected, the trailer lights will demand power from the harness but the harness itself will barely draw any power unless connected to a trailer.

Part # 118715 is made by Tekonsha and # C56320 is made by Curt. Between them both I recommend the Tekonsha. Our installers here tend to have better luck with the Tekonsha wiring products.
