Features:

  • Provides a 7-way, blade-style trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 4-pole, 5-pole and 6-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection point behind rear tire

Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the rear tire, on the passenger's side.


Once installation is complete, the 7-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 plug on your automobile and the 7-pole connector itself - to help prevent corrosion.

Product looks good however I haven't installed it yet due to the fact that I didn't order the mounting bracket for the plug. For others, you need to order the mounting bracket for this item unless you plan on drilling your bumper or vehicle body. 260208

Ordered the 7 pin harness for our 2014 Explorer to tow our camper. Was a direct plug and play for our vehicle. No need for splicing. Very happy with this purchase! Took all of about 15-20 minutes to install. Would recommend to anyone. 844777

First wiring harness sent was not correct. This item was recommended by etrailer employee. Telephone call with another employee straightened it out and return was easy. The hitch looks nice, except the screws on the bracket (4) have all rusted and look bad. My vehicle is a Ford Explorer XLT. When it's all washed and waxed it looks great till my eye sees those 4 little screws. You've reminded me how much it bothers me so I will get some quality black screws to replace. I am subtracting a star for the incorrect info I initially received and one for the cheap rusty screws. 816911

Just what I needed to replace my damaged wiring harness. This one is made 10 times better than what the dealership had originally "hacked job" installed... only thing left to do is add the electric brake controller. But glad my wife's explorer is back to working with a trailer attached. Thanks again etrailer for the grrat product and for answering my questions. 773168

Normally I dont take the time to write a review, if I'm happy I keep the product, if not I return it. This is one of the few times I dont mind writing a review. Took me 10 minutes to install. The directions are clear and easy to follow. I reviewed the video after I finished and it's not really necessary, maybe a better explanation of wire routing and secuing. 2 suggestions I would like to make. First is include the mounting bracket with the harness. I made my own on the fly, but not everyone will have time or ability to do that. Secondly team up with another company to sell a "new installation kit" I bought the Reese Towpower Trailer Hitch 84034 for my explorer and had to find a wiring harness separate. Would have made it alot easier if I found both in one shot. Total install time was roughly an hour. I installed the trailer hitch first and then worked on the harness. I should have started with the harness so I could easily route the cable, install the hitch then finish on the cable. Live and learn. Hitch was 45 minutes, wiring was 10, and made a bracket in about 2. 756240

Plug-n-play literally. Had an aftermarket hitch installed on my 2018 explorer with a 4 pin connector for a u-haul car hauler. Working on getting my own flatbed car hauler and need the brake controller hookup. Easy instructions - too easy, had to look at it for a minute before realizing how easy it was. Would be better with a mounting bracket but was able to zip tie to the bumper next to the hitch. 749532

I own a 2012 Ford Explorer Limited. This SUV was missing the wiring harness for the 7 way trailer plug. It also has the 4 rear proximity sensors for rear parking. This is the correct harness (118272) for my Explorer. Everything plugs in directly and has the correct plug for the Proximity Sensors. One thing you will have to do is connect each wire into the back of the 7 way. Directions and wire colors are correct. The wire ends will snap into the back of the 7 way. They only go in one way, so make sure you have the wire ends oriented the correct way, don't force anything. I tested the 7 way and the proximity sensors and everything is correct. The only issue is, this does not come with the 4 way connector. Which I don't need. If I ever do, I will just tap into the current harness and purchase the OEM 4 way Ford connector. 720010

Attached easily to existing wiring on my 2015 Ford Explorer. Only problem I had was it did not come with a plate to attach the plug to the tow hitch so that was disappointing. Had to make my own, lucky I had a plate from an old set-up that I configured for my use. 655982

  • Does 7-Way # 118272 Fit 2016 Ford Explorer
    For your 2016 Ford Explorer the Tekonsha wiring harness part # 118272 is a confirmed fit. This will fit whether or not you have the tow package. It fits both configurations. You have the connector on your vehicle that this will plug into and all of the pins will be active.

  • Recommended 7-Way Wiring Connector for a 2016 Ford Explorer
    It sounds like you have found the rectangular plug that is indeed used for the trailer wiring. The 7-Way that I recommend using is the Tekonsha T-One # 118272 because we have found the Tekonsha wiring products to be very reliable. You can use the mounting brackets # PK12711U and # C57202 to secure the 7-Way connector to the rear of your 2016 Ford Explorer. I have attached a video of this connector being installed on a similar 2016 Explorer that you can reference. It also shows where...

  • 2015 Ford Explorer Brake Control Installation
    According to my Tekonsha contact, your Explorer should have a brake controller connector, it would be located behind the handle for the hood release. You'll need the # 3035-P brake controller wiring adapter, which is compatible with Tekonsha brake controllers like the Prodigy P2, part # 90885. If your Explorer doesn't have a trailer connector, or if it has the 7-way, you'll install the 7-way connector, part # 118272 which would plug into the connector located under the vehicle behind...

    You will need to start with a 4-way. For that you would want the # 118540. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well.

  • Is a Powered Converter Needed for a 2018 Ford Explorer
    The circuit protection module as well as the converter module is already built into the trailer wiring circuits on a 2018 Ford Explorer so you won't need to install any of this separately. In order to activate the trailer's lights I recommend the T-One Vehicle Wiring Harness part # 118272 which has a 7-way.

    The T-connector trailer wiring harness # 118540 will plug into a 2016 Ford Explorer that doesn't have the factory tow package but all of the functions may not work; specifically the 12 volt circuit, trailer brake circuit, and reverse light circuit. To see if these functions work on your Explorer you can use a circuit tester such as # 40376 or a meter if you have one and test the pins on the harness where the T-connector would plug in.

    On the 2014 Ford Explorer, the Tekonsha T-One Vehicle Wiring Harness, # 118540, will allow you to install a 4 pole flat trailer connection. This harness will run the basic lighting functions on a trailer. If you decide to tow a trailer that has electric brakes, then I recommend the Tekonsha Prodigy P2 Brake Controller, # 90885, with the etrailer Universal Installation Kit for Brake Controllers, # ETBC7, for this vehicle. The P2 brake controller will work great on your Explorer....

Both connect with a round U.S. Car Connector like the one shown in the linked photo. If the Expedition has no factory trailer wiring you can still have a 7-way. You will start with the plug-and-play 4-pole kit # 118344 which installs at your tail light connectors with no cutting or splicing. If you need only basic lighting...

  • Will a Tow Ready 7-Way part # 118272 be Fully Functional on a 2016 Ford Explorer
    You can test all of the pins on the trailer connector for the 2016 Ford Explorer that you have found to see if they are all active with a circuit test like part # PTW2993, but I can tell you now that they should be (minus the brake output since you don't have a brake controller) all active. So to install a 7-way all you would need is the part # C56278.
