The assumption that ST was a designation for Standard Transmission was a falsehood.
The owner's manual is the official guide as it is directly from the manufacturer and if the vehicle is under a warranty there would be a great risk to that by violating any recommended usage.
Once again, I apologize for spreading misinformation and only wish my original post was open for Edit.
We bought the manual tranny Fiesta because you do not need to disconnect the battery. The brake lights work with any supplemental brake system. therefore no light kit is required. My main question was about "ReadyBrake" and if any one is using this system. It works on centrifical force with a cable running through the firewall attached to the brake pedal.
