How many ports does the diverter valve have?

The drawing shows three labeled ports: an INLET, OUTLET A, and OUTLET B, plus a small nipple at the top of the valve.

Which port is the inlet on the diverter valve?

The INLET is the horizontal port on the right side of the valve in the drawing.

Where are the two outlets located on the valve?

OUTLET A is the horizontal port on the left side, and OUTLET B is the vertical port at the bottom of the valve.

Does the drawing show a vacuum/signal connection?

This document is a simple line drawing (schematic illustration) of an automotive air diverter valve, showing the component's external shape and identifying its three hose connection ports. The valve is drawn as a cross-shaped body with a small vacuum/signal nipple at the top. Three arrows label the ports: "OUTLET A" pointing to the left horizontal port, "INLET" pointing to the right horizontal port, and "OUTLET B" pointing to the bottom vertical port. No part numbers, dimensions, year/model applicability, or written instructions appear on the drawing itself. Based on the uploader's album context, the illustration is filed among 1990 Ford Bronco emissions documentation and appears to depict the Thermactor (secondary air injection) diverter valve, which routes air pump output between two destinations depending on the control signal. A reader can learn from this drawing how to orient the valve and identify which port receives incoming air (the inlet) versus the two outlets, which is useful when connecting or replacing air injection system hoses.
