Thankyou for the video, but I need to know which colour from the foot pedal wires you connected to the middle of the three pins on your potentiometer. On the video, I can only see a green clip from a test lead. As you can see on my attached picture, I have one black, one green and one red wire which connect the foot pedal to the control box. Did you connect the black wire to the green test clip, or one of the others?
