Ford ISC-BPA Idle Air Bypass Solenoid Connector Pinout - ISC (-) & VPWR (+)

This document is a simple connector pinout diagram labeled "ISC-BPA" (Idle Speed Control - Bypass Air). It shows the face view of a two-pin electrical connector for the ISC-BPA solenoid, with the two terminals identified: one pin labeled "ISC (-)" (the idle speed control signal/ground side) and the other labeled "VPWR (+)" (vehicle power, the positive supply side). A diode symbol is drawn internally between the two terminals, indicating the solenoid contains an internal clamping diode across its coil. The diagram allows a reader to identify which connector cavity carries switched vehicle power and which carries the computer-controlled ISC signal, which is useful for testing the solenoid, back-probing the circuit, or diagnosing idle control problems. The document contains no year, model, engine, wire color, or part number information, it is purely a terminal identification drawing for the ISC-BPA (idle air bypass) solenoid connector. It was uploaded as part of an album of idle air control reference documents attributed to a 1990 Ford Bronco, and nothing in the diagram contradicts that application.
