Parts Needed to Add 4-Way and 7-Way to 2023 Ford Transit T250

Question:

I need both flat 4 and round 7 connectors added to our 2023 Transit 250. Do you need additional info regarding existing Factory wiring? Please advise. Thanks!

Hey Cj! The wiring depends on whether or not you have the factory tow package. If you do have the factory tow package all you need is the 7- and 4-Pole Trailer Connector Socket # HM40975. The wiring connector would look like the one pictured below, probably plugged into the back of a dummy plug at the bumper.

If you don't have the factory tow package you need the Curt # C56327 along with the Universal Installation Kit for Trailer Brake Controller # ETBC7 to upgrade to a 7-way. I went ahead and attached some installation videos below for your reference. If you have any other questions feel free to reply in the comments.

Hey Cj, did you find out if your Transit 250 has the factory tow package? I'm curious to know how the installation went for you, as it could help others looking to add similar connectors.
