OK, not only did the cruise control act reliably, but it seemed to be much, much smoother than before! I don't know about the circuitry, but it was so smooth you almost could not tell it was on! I never had it like this!

A couple of notes:

(1) The electrolytic capacitors have polarity. For anyone doing this, make sure you put them in correctly, unless you want them to pop like small firecrackers.

(2) Putting the unit back in was a real pain, because the screw (10 mm bold) that bracket holds on to by the pedal will keep on retracting as you are trying to mount this. After a couple of hours trying, in really tight space, I gave up and bought the same bold almost twice the length. This allowed me to install the unit in minutes - I just let it hang on the super long bolt as I screwed the nut on top. There is plenty of room for the longer bolt, and it will save you tons of time and bad language.

So the conclusion is: When you re-solder, replace the electrolytic capacitors!
