• What Wiring and Brake Controller do I Need for My 2018 Ford F-150 with Factory 4 Flat?
  Hello Casey, Thanks for reaching out, I’m glad you found us! Since your 2018 F-150 already has the factory 4-flat, you’re in a great spot to upgrade to a 7-pin/4-flat combo, and the nice part is you won’t need the # ETBC7L you were originally looking at. What you’ll want to start with is the Curt T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector # C56413. This is a plug-and-play option designed for your truck that will give you a 7-way connection at the rear by tying into...

• Parts Needed To Add Hopkins 7/4 Pole Connector To a 2020 Ford F-150 With Factory 4-Way
  I have a couple ways you can install the 7- and 4-Pole Trailer Connector Socket # HM40975 on your 2020 Ford F-150 with a 4-way flat factory connector. The first is going to be the easiest but is more costly. You will use the harness from the Curt 7-Way # C56413 and connect to the connector you found. The Curt harness will connect to the factory wiring as seen in the installation video I have linked near the bottom of the page. Otherwise we do have the Hard Wire Connector # 20147 which...

• 7 Way Connector for 2019 Ford F-150 without Factory Towing Package
  You can install a 7 way connector on your 2019 Ford F-150 by using the Curt T-Connector # C56413, which will plug into the factory supplied 4 way connector plug on your vehicle and give you a fully functioning 7 way connector. If you've got a plastic bumper, I don't see any reason why you would not be able to cut a hole for the plug to be installed next to the license plate holder; however there is not a specific installation kit that makes this possible and you would need to do the cutting...

• 7-Way and Brake Controller Solution for 2018 Ford F-150 without Tow Package
  Your 2018 Ford F-150 without the tow package and 7-way does have brake controller wiring currently so once you have the 7-way part # C56413 installed you'd be able to easily install a brake controller using the truck's factory wiring. The P3 part # 90195 and the install harness part # 22292 would be a really great and easy to install option. This is the most advanced and easiest to use brake controller on the market so I recommend it highly.

• Troubleshooting 12 Volt Power Circuit of 2019 Ford F-150 Trailer Wiring Not Active

• Best Way To Add 7-Way To 2018 Ford F-150
  Hey Scott, thanks for reaching out. So the Curt T-Connector # C56413 you ordered is intended for vehicles with a factory 4-flat connection. It sounds like your 2018 F-150 does not have a factory trailer connector, which explains why the # C56413 is not working correctly. Your vehicle is missing the necessary OEM wiring components to make it work. If you need to add a 7-way to your truck, it can be done, but you will have to do some wiring. Adding a 4-flat and 7way combo will be the best...

• Will Curt 7-Way Trailer Connector for 2019 Ford F-150 Charge a Trailer Battery
  The Curt harness you purchased (thanks by the way) part # C56413 is a fully functioning 7-way connector after you install it so it has a 12 volt circuit supplying power to your trailer's battery. With that being said you won't be able to charge up your trailer battery if it dies from the truck because there just isn't enough amperage. It's meant to maintain the trailer's battery while traveling to keep the battery from dying. To charge a trailer battery you need something like part #...

• Solution for 7-Way Wiring On 2023 Ford F-150 XLT

• Parts Needed to Install 7-Way on 2015 Ford E-350
  Hey Ethan, if your 2015 E-350 has a 7-way wiring harness the correct part number you'd need is the part # A10-7072VP which would plug right into a round connector that looks just like the part # 20147. With that said do you have a 4-way currently and are looking to install a brake controller? If that's case you would need the part # ETBC7 with a brake controller like the part # 90885.

• Troubleshooting Curt T-Connector Not Working on a 2018 Ford F-150
  What I would do is try bypassing the tee connection on the Curt T-Connector # C56413. If you plug everything back up how it was before you installed this kit then you can test the 7-Way at the back of your 2018 Ford F-150 to see if everything is functioning properly again. If it is functioning properly then the T-Connector needs to be replaced. If it isn't then you'll want to take a circuit tester # PTW2992 and check the OEM wiring from the rear as far forward as you can. While doing...
