Pressure and vacuum connections at vacuum amplifier

ATM Air admission to vehicle interior
EGR Vacuum to ARF switchover valve
VAC Vacuum from vacuum pump
VCV Vacuum from vacuum control valve

Note: Vacuum control valve modified. Restrictor integrated in vacuum control valve, the restrictor in the vacuum pipes is thus discontinued.

Production break points: as of July 1994
