Question:

I have a 2021 Ford F-150 XLT and want to install a 4-pin flat connector. Do you know if anyone makes a custom connector that plugs into the existing wiring harness of the truck? Thank you for any help you can give me.

Expert Reply:

When choosing the correct 4-flat wiring harness for your 2021 Ford F-150 that already has the factory 7-way I recommend The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C75WR. I like this harness because it is constructed using surface-mount technology that gives it a consistent, reliable performance. This harness will plug into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights.

Just a quick note that this harness is intended for vehicles without LED tail lights and will not work on models that have the backup sensors installed. I attached a review video link below explaining more features of the harness. If you have any other questions please reach back out to me and I will be more than happy to help you further with your towing endeavors.
