The system works like this:
The air pump connects to the air control valve (ACV). There is a nipple on the top of the ACV that has a vacuum hose that will run to a pair of emissions solenoids on the rack. These solenoids are connected to the ECU, which grounds them at 3800 RPM & 5200 RPM. This allows air to make its way to the VDI actuator (driverside of upper intake manifold, UIM) and 6-port actuators (passenger-side, LIM). There are metal hardlines on the emissions rack connecting everything.
So depending on what exactly the previous owner (idiot) removed, there could be a few components to pick up again. There are also a pictures of the VDI and 6PI systems in the factory sevice manual (FSM). See the FAQ for download links.
