Does anyone know if the 2020 Highlander Limited Platinum edition has any wiring installed for future trailer wiring? If not, I would think the best wiring method would be to use a module and clip-on pick up sensors that attach but not cut into the existing wiring. These new electronic systems can detect any parasitic wiring and Toyota I think frowns on violating their wiring? I forgot to mention that the platinum edition has no provision for trailer hitches because of the kick- to- open tailgate sensor located in the bumper. Bummer!!!!!
