As you well know these cars are complicated, so yeah, I could have fnorked something up when I replaced the clutch master.

But what could possibly be down there that would cause the AIC to stop working? That seems to me to be the real issue: with a good AIC, good ECM, correctly working TPS, and good wiring between the ECM and AIC, why is the AIC not working?

Is there a sensor or switch somewhere, other than the TPS, that directs the ECM to operate or not operate the AIC?

Regarding grounds, I soldered all the lugs and sanded the connections on the engine lifting grounds, the ground in the driver's side fender well, and the ground at the radiator. Have I missed any grounds?
