I've checked my FSM's and I still can't find out where the outlets coming off these coolant and water lines go to...little help?!

Where do the outlets on these coolant and water lines under the intake manifold go?

Where does the outlet on the bottom of this water line go...

...do either of them have anything to do with the two small outlets on the back of the IACV? Where do they go? I've checked the manual and looked at pic after pic of peoples engines and I still can't figure it out...any help would be greatly appreciated!

 

i have not really worked with the SR intake manifold but those two nipples look just like the KA coolant feed lines...

ps

feed and return can come from anywhere .. you can cap them off and tap into anyline

 

the two nipples in the first pick go to into the upper half intake manifold...the ones in the second pic go into the throttle body, they hold coolant, i had this same problem when i was re-building my SR a while back, good luck
