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
    • Plug in T-connector
  • Constructed of 16-gauge bonded wire

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.

No trouble with installation and wiring was almost as easy. I would get another hitch here in a heartbeat.



by:

Everything came quickly and was easy to install with one other person to help. The instructional video was a huge help. Specific to my make ,model, and year. Definitely would buy from E trailer again.

2015 Ford Explorer

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.



by:

I didn't realize it's been a year already. Trailer brake works GREAT. Was even able to hide the control box for a complete factory appearing install. Highly recommend this unit if you need a trailer break. You won't be disappointed.

2018 Ford Explorer

2018 Ford Explorer Limited. This item needs to include the mounting bracket. I had to shop around for one to finish my project. The instructions were also not clear for my vehicle. There were two sets of wires where it showed one. I took a gamble and choose one. It was more time consuming than expected. The 1 day shipping was also not one day. It took longer than expected to receive it. Otherwise, it works.



by:
2019 Ford Explorer

Excellent product but very poor packaging. Just threw it in a huge box with a hitch in it with absolutely zero packaging material, hitch had lots of paint chipped off of it and it was a miracle that none of the wiring was damaged.



by:
2014 Ford Explorer

The hitch was very easy to install once the brackets holding the mufflers were removed, a second person to help in holding the hitch when installing it is a big help. The “T” wiring harness was also easy to install, highly recommend using some sort of electrical tape to help seal the two connection pints from water / snow. The 7 pin / 4 straight adaptor is exactly what I needed, different trailers, different plug types.



by:
2016 Ford Explorer

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.

Very good and easy to install



by:

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

The harness comes with the trailer end wires taped together to allow easy routing to the hitch. The issue is no tape was used to insulate the wires from each other. This resulted in multiple blown fuses when i connected the harness to the car.Some additional tape or a warning to not plug in to the car harness until the trailer plug is connected would have avoided the problem



by:

Everything is going fine so far I installed the hitch, T-harness and 7 way plug on my 2019 ford explorer but now I need to find out what relays and fuses I need to install in the vehicle. Do you have a KIT with instructions and maybe a brake controller? Please

Etrailer Expert

According to the Ford website, you will need a 30 amp fuse in location 27 and a relay in location 37. The M-case fuse is available from an auto parts store, but you might need to see the dealer for the necessary relay. To activate power to the brake controller plug under the dash, check location 46 for a 30A J-case fuse and install one if its missing. In the fuse panel in the passenger compartment, make sure theres a 5A fuse installed in location 4. This panel is located under the dash to the left of the steering column. I recommend the Tekonsha P3 brake controller part # 90195 and the adapter for Ford Explorer part # 3035-P. The P3 is our most popular and reliable brake controller.



by:

Wiring harness was a little involved but it was due to Explorer having custom hitch mounted. Overall it did not take long and I am still very happy with my purchase, works great!

Still working as expected and looks like it did the day I installed it. Worked out great!

Hitch went in without a hitch. The wiring harness routing per the video became a problem and had to come up with another route, otherwise it was very good.

It works well and consistently without any problems



by:

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.



by:

This was very easy to connect. Easy enough for a women to do! I highly recommend this wiring harness. Worked great for my pop up camper and 2017 ford explorer!



by:

Great product, well made. My only complaint is that I wish I had noticed it didn’t include mounting bracket for the 7-way hookup

by:

The wiring harness (pn 118272) fit perfectly, no problem. A little daunting to get the factory connectors apart but after that, simple
The hitch (pn 76034) fit like a dream. HOWEVER, I had to make a trip to get replacements for the 7/16 x 2.5 carriage bolts -- could not in any way tighten the nylon lock nut because the stove bolt shank could not be held in the slot. The replacements were 12mm x 60mm carriage bolts. Draw-tite should change their hardware. Also, the bolts provided to attach the hitch to the car frame were standard zinc coated -- the factory bolts I removed were galvanized. Again, Draw-tIte should change their hardware
The trailer socket with mounting bracket (pn HM40975) just plain will not fit on my car unless I mount it below the receiver (not a good idea). Not sure what I'm going to do yet but may have to fabricate something.
Overall, great product but be prepared to use other than the hardware provided by Draw-Tite.

This is one of many products I have purchased from etrailer.com the past several years. The wiring kits and hitches that I have purchased have all been accurately described and received quickly. etrailer.com is my "go to" distributor for hitches and wiring kits.

The harness fit easily and is still working great. It looks like it was a factory install



by:
2017 Ford Explorer

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.



by:
2012 Ford Explorer

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.

    The Tekonsha T-One Vehicle Wiring Harness # 118599 is the only one confirmed to fit your 2021 Ford Explorer that did not include factory trailer wiring. This will give you a 4-way flat trailer connector and uses OEM style taillight connectors to reduce wiring. This kit will not work with Police Interceptor models.

  • What Weight Distribution Hitch and Brake Controller do You Recommend for My 2018 Ford Explorer?
    For a great option when towing with your 2018 Ford Explorer XLT with a 8k trailer with around 1,000 pounds of tongue weight, I recommend the Equal-i-zer Weight Distribution System w/4-Point Sway Control # EQ37100ET. Not only does this system provide you with 10k pounds of maximum gross towing weight and provide you with the 1k of tongue weight you need, it also gives you the anti-sway results you are looking for to increase overall control. Since this setup comes with a 2-5/16 inch ball,...

  • 118540 Trailer Harness on 2019 Ford Explorer Causing Blind Spot/Cross Traffic Monitor Malfunction
    Per our records, you purchased the # 118540 harness. I checked with my contact at Tekonsha, who tells me that it sounds as if you have the # 118540 harness you purchased plugged into the wrong connector under the vehicle. There is a gray connector and a black connector. The # 118540 should be plugged into the black connector. If it's plugged into the gray connector, it would cause problems such as those you described.
