Send me a PM with your email address and I will send you a PDF of the ATC manual. It only applies to 1965 and 1966 big Pontiacs but should interest you.
From a diagnostic perspective the 1965 and 1966 Pontiac ATC units are virtually identical although changes were made mid year in 1965 to some ATC components and many part numbers between the two years are not the same (although they look identical). 1965 big Pontiacs also had an ATC temperature sensor in the instrument panel dash pad while 1966 big Pontiacs had it under (and not part of) the dash pad.
Always interesting trying to debug older technology.
