Pcv hose. The white piece does two things. It holds the hose onto the inlet and plugs into another plug. The plug is just a short. When the hose is intalled correctly the circuit is closed and the ecu knows that pcv is connected. On aftermarket pieces you just short out the connector or solder the wires together.
