87' TII Where do the two openings here go? One is on the UIM and the other is the small one on the stock intercooler.

Thanks guys

 

Anyone? I'm pretty sure they can both be capped. I have no idea what went to the intercooler one unless these two went together for some reason

Also, should I "T" into the constant vacuum before or after the pcv valve for the charcoal canister for my catch can setup?


EDIT: I used the nipple on the back of the UIM for my boost gauge (I hope that's a vacuum source...) and I T'd before the PCV valve.

Still don't now what that IC nipple was originally used for. Does anyone know if this is a metered vacuum* source?
