Video Transcript for Tekonsha Custom Fit Vehicle Wiring - Trailer Hitch Wiring - 118272 Review

Today we're going to review part number 118272. This is the tow ready T-One vehicle wiring harness with the 7-Way trailer connector. This is a custom fit part number. It is designed to fit the Ford Explorer starting in 2011. What I do recommend on a custom fit part is to always go to our website, use our fit guide, put in your year and model vehicle, and it'll tell you if this part will work for your application. This part provides a 7-way blade style trailer connector at the back of your vehicle to power your trailer signal lights.

It does connect quickly and easily. There's no cutting or splicing of wires. Basically all you have to do is, the T-connector would plug into a point on the rear of your vehicle and you take your wires here, unscrew these screws here so this would come out, run these wires through here, and then you'll have your connection points that you'll just have to connect these to. What I would recommend is, once you plug this in, instead of going color for color, once this is plugged in just test each wire with a circuit tester to determine what function it is and then just wire it up to the 7-way correctly. The T-connector, this will connect to a connection point behind the rear passenger tire. Basically what you would do is, there's a tow plug harness underneath the vehicle on the passenger side and the connection point is behind the rear tire, and it will have connectors that will match this T-connector harness. You just unplug it and you plug one into there and then the part you unplugged you'll plug into the other side, and then you'll be ready to go.

It supplies power to these wires. This part does come with everything shown here on the table. The wiring harness, the 7-way connector, some cable ties to tie up any slack in the wiring harness, and a nice set of detailed instructions that will explain how to install it and even shows some pictures of where the connection points are. That should do it for the review on part number 118272, the tow ready T-One vehicle wiring harness with the 7-Way trailer connector.

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

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

by:

Product shipped quickly! Went together exactly like the videos. The reason for only 4 stars was the zip ties were too small and the bracket to attach the plug had screws to drill into the bumper but we wanted to bolt onto the provided bracket on the hitch. 634368

The light kit does not contain the connector mounting bracket. The bracket is shown in the photos of the kit. The kit description does not say the bracket is not included. I am unable to complete my install with out the bracket 633261

After having an awful experience with a large chain camping store with the installation of the wiring on my vehicle. I was able to undo all the damage they did and use item #118272 to wire up my vehicle with a 7 point plug. It took me about 10 mins to wire the adapter in, while it took the company over 8 hours to cut into my wires (with only turn signals working) instead of using this adapter. Everything worked with no issues and was easy to install as the provided video described. 523604

  • Needing to Install a Brake Controller 2017 Ford Explorer with Ford Factory Class 3 Tow Package
    If your 2017 Ford Explorer has the factory prep towing package installed, then you might have a brake controller plug-in wiring on the vehicle to connect your brake controller. However, not all models with the tow package had the wiring installed and you might have to install an extra kit. One way to check would be to see if you have a 7-way trailer connector already installed on the rear of your Explorer. If the 7-way is present, then you should have the prep wiring install to plug...

  • Do Trailer Hitches for 2018 Ford Explorer Affect Hands Free Liftgate Operation
    The Draw-Tite # 76034, Curt # C13386 and etrailer.com # e98867 trailer hitch receivers that are designed for your 2018 Ford Explorer will allow the hands free lift gate sensor to work. However, you will need to activate it by putting your foot to the side of the hitch receiver opening with both hitches. The sensors will not recognize your foot through the hitch unfortunately. You would not need to relocate any sensors either. I've linked videos of both hitches being installed for you....

When adding a 4-Way trailer connector, # HM40285, to the Explorer it does require a direct connection to the vehicle battery so it does have a powered converter.

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.
