3-Port Boost Control Solenoid Port Identification Diagram - Subaru Impreza

This document is a minimal schematic diagram identifying the three ports of a solenoid valve, uploaded as part of a Subaru boost system reference set. The valve is drawn in black silhouette, and three callout labels identify its connections: Port 1 extends horizontally from the left side of the valve body, Port 2 rises vertically from the top, and Port 3 extends horizontally from the right side. No part numbers, wiring information, hose routing instructions, model years, or applicability statements appear in the image. Given the filename (SubaruBoostSystem_17.jpg) and the companion file in the album (3portDiagram.gif), this appears to be one page of a multi-page set illustrating a 3-port boost control solenoid, likely used to explain how vacuum/boost hoses should be connected when installing or servicing an electronic boost control solenoid. A reader can learn only the physical location and numbering of the three ports on the valve from this page alone; other pages in the set presumably explain what each port connects to (e.g., turbo compressor source, wastegate actuator, vent). The document itself contains no year, make, model, or engine identification.
