>Does anyone know if there are pneumatic tubes in the ACC systems of the '96
>900 SE Turbos? Or even how to get to them?

Pneumatics are relics of a prior century, I believe. The 9000 and 9-5 ACC
functions are all done by electric motors, and since about 1990, the 9000
has used stepper motors at that. While pneumatics are light and the energy
source is free, hoses break down with time, proportional control is
difficult to impossible, and computer diagnostics are a big problem.
