Exclamation 3 vacume hoses behind intake manifold

Real quick can any one tell me what the three vacume hoses hook up to on the back of the intake manifold facing the fire wall. I got two of them hooked back up but I can't figure out where the last one goes. Thanks in advance...

OMP = oil metering pump
LIM = lower intake manifold

Only one is vacuum. That is the bottom one and it goes to the water thermo valve for the secondary throttle plates.

The largest is a filtered air supply for the oil injecotors.

The other is for the PRIMARY fuel injector air bleeds. It supplys a filtered air source for the primary injector air bleeds.

There is a free fsm available online.
