Question:

Is the answer for the 2018 about going from a 4-way to a 7-way also true for the 2019 Subaru Forester?

Yes, the answer applies to your 2019 Subaru Forester as well. You can install a 7-Way connector on your 2019 Subaru Forester that is already equipped with a 4-Way. If you will only need to power the basic signal lights on the trailer that is equipped with a 7-Way then you can use the Hopkins Adapter # 37185. This will plug right into the existing 4-Way on your Forester to provide both a 7-Way and 4-Way on the other end. After attaching the white ground wire to a bare metal surface the additional wires can simply be tied off as they won't be needed.

If however you plan on towing a trailer that is equipped with electric brakes you will instead want to install the Universal Wiring Kit # ETBC7. This kit includes everything needed to convert the existing 4-Way to a fully functional 7-Way (and 4-Way), along with the additional wiring and circuit breakers needed to install a brake controller.

Then for a brake controller I recommend the Tekonsha Prodigy P3 # 90195. This is a proportional controller that will activate the trailer brakes at the same time and with the same intensity that you apply them in your Forester. It features an easy-to-read digital display, storable settings, and continuous diagnostics that will alert you to any potential issues.
