Cruise control kit [E4TZ-9A818-A] - remanufactured

I thought Ford "speak" was speed control?

Yes, Ford called it "speed control", and the story I heard was that someone patented the term "cruise control" so Ford couldn't use it.  And in their literature they called it speed control, as shown below.  But apparently Specific Cruise System, Inc got to call it what they wanted to in their own literature.

That's a different system than I've seen before.  It has the same turn signal-mounted control that the Dana ones used, but has a different servo and control valves.  And it uses a Ford-style vacuum reservoir and vehicle speed sensor.
