Speed control is Ford's term for what is typically called "cruise control". This page is to capture the components specific to that function.
1980 - 86
For those who might be considering using the later version of the speed control in their Bullnose, here are the pages from the 1996 EVTM re that subject. I believe the speed control kit is F2TZ 9A818-A and fits 1992 through 1996.
If you are troubleshooting problems with your speed control, don't miss the Technical Service Bulletin on them: 90-25-12 Speed Control.
