cruise control ap50

I really doubt that, the instructions that came with my unit say nothing about other inputs.
Have you checked the brake and clutch switches? If the wiring there comes off (or switch goes faulty)the cruise control stops working.
My control stopped working once and only after I checked everything else I found the clutch switch had moved out of alignment. The speed sensor is pretty rugged, you could have lost the magnets but that would be obvious to see.

I have had 2 of these fitted over the years, one manual, and the other electronic.

Had trouble with the vacuum actuator on the original one only, so I gave them a call on 02-9316 5033, if they are still there.

There is a test mode, that you can switch into at startup, (on either)

The Electronic one has been simply brilliant.
Sorry I cannot be of more help
