Parts Needed to Install Tekonsha Brake Controller in 2021 Porsche Cayenne with Tow Package

Question

Question:

I have a 2021 Porsche Cayenne Coupe with tow package. I need a plug in electric brake controller. I see you have a techosha brake controller and plug in wiring. I actually already own that controller, but I need the little plug in harness to connect it to the Porsche. Do you offer that?
