I bought a S14 but it comes with a S13 SR20DET that is replaced by the previous owner. Some of the vacuum pipes are disconnected (Circled). Does anyone know where these vacuum pipes should connect to?

Thats the Exhaust Gas Recirculation valve - the small hose on top goes to the EGR control valve on the firewall, the big ones below that go to the exhaust dump pipe and the air intake, but I can't remember which goes to which.

Thnaks Metako42, would it be any issue if just leving the EAI valve and the big ones below diconnected?
