Expert Reply:
Your 2021 Volkswagen ID4 has the PWM-STT wiring which means that the stop, turn, and tail light signal all run on the same wire.
You'll need to follow the PWM-STT Wiring diagram found in the instructions of the Curt # C59236 which I've linked below to make sure you get everything installed correctly.
