  • Provides a 7-way, blade-style trailer connector at the back of your vehicle to power your trailer's signal lights

Installation

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

This product makes the wiring process extremely simple. I have wired many vehicles over the years. and it can be frustrating and time consuming. However, this harness was WELL worth the price to eliminate poor connections and save time. I would rather be fishing or golfing!!

Great! I have used this extensively and is holding up great with my camper and my boat.

The part was delivered next day and the installation video was very helpful. It truly was a plug, wire and play setup. Installation took 20 minutes. The hardest part of the installation was removing the spare tire to access the Ford factory wiring harness.

The website made the recommendations for my truck, which allowed me to find the exact part for my aftermarket trailer brake controller.

The Ford dealer wouldn’t help or recommend anything for aftermarket parts, and suggested an $800 tow package installation as my only option.

This part was 10% the cost of a factory installation and it is truly a DIY project for any level. All the lights and trailer brake controllers worked perfectly. Just follow the wiring diagram provided to get your trailer on the road just in time for the next towing event.

This was a perfect fit for my 2018 f150 xlt 5.0 4x4.. it took like 20 min to install paired with a tekonsha brake controller and it works great!

e trailer is the best, James Y took care of the the only problem I have ever had, he and everyone there are just wonderful. The shipping is top rate 2 to 3 days max! I will use e trailer for everything I can1

very pleased! fast shipping! right part the first time! and they make it easy being plug and play! two thumbs up!




by:

I haven’t installed the product yet, but I accidentally put the wrong shipping address and it was shipped already. Once I found out I emailed etrailer and they got it all figured out for me. Great customer service and will be purchasing more items in the near future!




by:

Highly recommend this to anyone! It was relatively easy to install (the video attached to the tracking info helped tremendously with that). Super simple "plug and play" wire connections. The only downside- you need to order the support bracket separately. I decided to mount mine next to the license plate in the bumper so I had to buy some small bolts to attach it to the bumper. Had both the wiring harness and the hitch installed in about 2 hours.

The ground pin was very difficult to install on the plug. I had to remove the boot cover and apply liquid electrical tape.


Comments
Hello Brad, Thank you for leaving a review! These wires can vary in length and can be tricky to get in the back of the plug. From experience, I have found starting with the ground is usually the best way to get the wires plugged in. If you do apply silicon or anything that seals the connector just make sure the pins arent covered in the connector.

Easy install. Be sure to order the correct mounting bracket for the 7 blade plug, if needed. Didn't see a "recommended" bracket part# on the T harness product page. Ordered what I thought would be the correct one, now I have an extra paper weight. If you intend to mount the 7 blade plug on the bottom side of the bumper, I would suggest mounting your hitch (if needed) first before drilling the 2 mounting holes. I had to move my original mounting location due to clearance issues after installing the hitch on a 2018 Ford F-150 XL step bumper.

Product exactly as described, easy to install, and has held up well so far. I generally pull a trailer every couple of days and this made it way easier than trying to hard wire a new harness in.




by:

I don't know where to start when reviewing this company. First, the products they sell are top notch, at prices no one can beat. Secondly their online support with videos and detailed installation procedures is "unmatched" by any online company. If they can't walk or talk you through it, it probably can't be done! But perhaps the best quality product they have is their staff. When you call they are most courteous, extremely helpful, and will go above and beyond making your transaction right. I have purchased from etrailer numerous times for these very reasons. And my latest purchase ran into shipping problems (not etrailers fault) and yet Stacey A., Greg & others whose names I forgot (my apologies) made it right. Bottom line, as a frequent online shopper, I can only wish that other online companies would look at etrailers business model and choose to emulate them. This is how online SHOULD be. Thanks again etrailer.com

Everything works like it was supposed to, it was pretty easy to install, but it didn’t come with any mounting hardware for the plug. And I had to call to get some clarification about the plug, but the girl I spoke to had no idea . She just read the description to me. However, it does work, and it went together well.

Easy to install took about 15 minutes. My 4 year old grandson enjoyed helping handing me the bolts and nuts when installing the hitch...

This is the easiest way to install a 7 prong plug on a 2018 F-150 with a 4 prong already installed by the factory. Plug and play. Mine already had all the wiring in the factory plug for the upgrade. No need to run a brake control wire from the cab to the plug.

    To add a second 7-way to your existing 7-way on your 2015 Ford F-150, you will not want to use the T-One Vehicle Wiring Harness with 7-Way Trailer Connector # 118283 but rather the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness with 7-Pole Plug # 41157. This will connect between your current US Car Connector wiring (standard on most trucks) and 7-way connector to give you a T-connection and second fully functional 7-way trailer connection.

  • Rectangular Connector for 2018 Ford F-150 Trailer Wiring Harness
    The Reese Multi-Plug Wiring Harness # 74682 is meant more for replacing or upgrading a current 7-Way connector on a 2018 Ford F-150 right at the round US Car Connector. For your rectangular connector that you found you can use part # 118283 instead. Since this only comes with a 7-Way you can upgrade it with the Reese plug so that you have both a 7-Way and a 4-Way readily available for different types of trailer connectors.

And then to convert that to a 7-way and 4-way you'd replace the included socket of this kit with the part # 74682 and you'd have a fully functional 7-way and 4-way for your truck.

  • Troubleshooting Trailer 7-Way Connection Between 2004 Chevy 1500 and 2015 Ford F-150
    The Ford Replacement OEM Tow Package Wiring Harness, 7-Way # 118242 is the correct harness for certain Ford F-150 models from 1997 to 2004. It uses factory specific plugs and then connects to a US Car connector at the 7-way and that portion is universal yet the t-connector is not. It sounds like you have a trailer that works on one and not the other and the issue with that situation is normally a ground issue on the trailer itself.

To install the Tekonsha P3 # 90195 brake controller, all you'll need is the # 22292 wiring adapter to connect the brake controller and the connector behind the dash as shown beginning at the 4:35 mark in the brake controller installation video I've linked for you.

  • Parts Needed to Upgrade Factory 4-Way on 2019 Ford F-150 to Control Trailer Brakes
    Unless your truck came equipped with a Ford factory trailer brake controller, you will need to install an aftermarket one in order to control the brakes on your trailer.

    You can either replace the entire setup with the # 118283 on your 2015 Ford F-150 (easiest but most expensive option), or you can extend the two wires on your truck frame to the 7-way you have now to completely activate it. I would go this route since it won't cost you much and you could go do it right now if you wanted to assuming you had 10 gauge wire like part # 10-1-1 (sold by the foot). If you check out the picture I attached you'll see where to find these wires.

    The 4-way and 7-way that's mentioned is regarding the trailer wiring connector at the rear of the 2020 Ford F-150. Most likely you have the 7-way which is the round connector that has 7 pins. So to install the Voyager # TK90160 you referenced then all you'd need is the part # 22292. If you do not have the 7-way and instead have the smaller flat 4 pin connector you'd also need the part # 118283.
