I am glad that you got your cruise working it remined me about a 82 suburban I has working on. the factory cruise it wasn't working properly so I was fooling around with it one day I had just left out the driveway and the truck got up to about 45 mph so I pushed the button and when I did the vacuum diaphragm sucked up and it held the throttle wide ass open it jumped up to 60 mph quickly I tried not to panic but I was headed towards the hwy I tried everything to get it to stop but the suburban kept getting faster and faster I hit the brakes as hard as I could it did nothing it just kept going I cut off the key and that didn't work so I then had to shift it up into netural it was screaming running wide open at about 7000 rpm but I was able to get stopped before I had to stop at the hwy I just knew it was going to spin a rod or something but it made it thru and after that I took off the vacuum diaphragm off and thrashed it . lesson learned
