I recently purchased a 201 and it has a knee pedal. I nned to know how to hook it up. I do believe the machine works but do not know how to connect the cord. It did not come in an original cabinet. I do have a cabinet with knee pedal in place but not sure how to do it.
From the motor you should have two wires, they screw intoi the control box that should be on the side of the cabinet and the knee control does the rest.
