Not knowing what year SC you are working on and based on your limited description it sounds like to be you may be talking about the PFE Tranducer for the EGR system. If so the vac. hose needs to be connected to the inlet plenum if memory serves. Sorry it has been a long time since I had my 89. My 92 has already had the EGR taken off of it.
