Hi Pete! I too have the cruise dilemma. Just spent 50$ on a guaranteed used accuator w/ no luck. I am assuming this must be an amplfier problem, but have read from the search engine that the entire system is just not that good. Some members would differ, however there are plenty of non working cruise control units in these cars: 126, 123, etc... I have come to the conclusion that a quality aftermarket unit w/servo controlled accuator would be optimal. I am going to take the plunge and spend 249$ via jc whitney and install one of these units on my 82 380 sel. I will also try to pinpoint the wires for the control rod and hybrid this to the aftermarket amp and servo. This way, the system will look factory. Iam now having trouble w/ my service cd; the electrical schematics will not load up. Anyone want to jump in here? les
