explorer intake here, a few Q's on install

[fiveohpatrol]

yah that hole on the front bottom of the upper plenum is the one that i was wondering that i should plug, could i just put a rubber snug fit plug over the tube or should i see if it unscrews and put in a screw-in plug? if i plug that one i think i can figure out the rest, if the T thats on it is a vacuum line and can be used to go to the FPR and one other place then i'm all set, i've got the lower on now and injectors and fuel rails in, just need to pick up a upper to lower gasket (couldnt find one today) and install that and i'll be done
