Helpful Expert Reply:
The stop light switch wire on a 2020 Ford Transit that will be needed to install a brake controller like the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 is violet/white. This wire should only have power while the brake pedal is pressed. The other option would be to obtain the same signal from the third brake light which requires running a wire from the rear of the vehicle to the front.
Please note, wireless brake controller like the Curt Echo Wireless Trailer Brake Controller part # C51180 don't require stop light switch connections.
