One of the smaller hoses attaches via a nipple on the shroud behind the Fan and alternator. That may be the 'C' hose.
Still some mystery to be solved by a sharper eye.

Thank You ! Indeed there is a nipple on the fan shroud what would the use be of pipe C ?

[E Sully]

The connection on the shroud is part of the fuel venting, charcoal cannister system.

Thank You all
Still wondering what the hole G is for any help ?

G... How about the rear bumper extension support

Believe 'G' is for a warm up hose going to the air cleaner snout.

[Trackrash]

^^^^ True. If your air intake snout was modified or removed this hose may have been eliminated. It was only there to please the Smog Control Gods.

THANK YOU VERY MUCH ALL OF YOU
I also have a non isolated electrical connection that goes to the right side near the ventilator that I don't know what it is for
