Expert Reply:
It sounds like you may need to check the Curt Spectrum Trailer Brake Controller # C51170 connection to the cold side of the stop light switch on your 2020 Toyota Tacoma. This will be on the pin related to the ride wire coming from the brake controller.
When installed properly the pin to the red wire should only be getting hot when you press on the brake pedal. If you're getting signal without touching the brake pedal then that would be why this light is always green.
If you are still having issues after this please let me know and I'll help you look into this further!
