Vac line route to ECU - Type 44 Mac 11

[Swann, Benjamin R. (BSWANN)]

Can anyone describe where/how the vac/boost line to the ECU in the 5000
Turbo Quttaro?  I checked out a car last nite that had no vac/boost from the
line at the ECU.  It would be good to check the obvious before replacing the
hose which routes from engine bay to the ECU - however it does.  Where is
this line tapped into in the engine bay? 

TIA
