I seriously doubt it. The power third row seats are part of a special option package. Ford has a habit of creating different wire harnesses for vehicles with and without specific options. (For example, my 2017 XLT has the 202a package but it doesn't include wiring for the rain-sense wipers.) If you're lucky, though, your SJB will still control the relay to power the seats. If you check the connector for that circuit (you'll need a factory wiring diagram) you can see if that pin/wire is already present at the SJB.
