A few days ago, I slapped a 99 EX intake manifold on my z6 head. And Im having a hard time figuring out the (CORRECTION I MEANT EACV) not IACV. My car is a 90 Si, converted to obd1. I bought the manifold with all the vacum lines disconnected, and I cant seem to figure out where the long end of the iacv goes. It starts from a nipple on the top of the plenum, but then it looks like it goes under the TB and towards the firewall. The only thing I can think of is that it goes to the charcoal canister ? Another thing, if I wired up this sensor to my original EVAC location, would the p28 ecu work with it ? Any info on this is greatly appreciated, Im kinda stumbled at this point.

for IACV, there is no vacuum lines, but 2 small coolant lines on the IACV, one of them goes to the bottom of the TB, and the other one goes towards the back of the block (i was looking on mine in my garage and could not see exactly where it goes), but i would believe it go to to the back of the block

 

My mistake, I was reffering to the EACV, I wasnt familiar with what it is called on 92+ cars.
