Ford Bronco IAC / Throttle Air Bypass Valve Solenoid Wiring Diagram (C160, S165)

This document is a cropped portion of a Ford wiring diagram showing the Throttle Air Bypass Valve Solenoid (idle air control) circuit. The diagram shows connector C160 at the top, with power feed circuit 361 (red wire, R) splitting into two branches: one branch feeds a diode, and the other feeds the Throttle Air Bypass Valve Solenoid, which is drawn as a coil symbol. The output side of both the diode and the solenoid connect to circuit 67 (gray with white stripe, GY/W). The two GY/W wires join at splice S165, and circuit 67 GY/W continues downward out of the frame, presumably toward the engine control module ground/control side. A reader can learn the wire circuit numbers (361 and 67), wire colors (Red and Gray/White), the connector designation (C160), the splice identifier (S165), and that a suppression diode is wired in parallel with the bypass valve solenoid. The scan was uploaded as part of a set of idle air control (IAC/IAB) reference documents for a Ford Bronco; the filename suggests it depicts the 1986 Bronco IAC schematic, though the visible portion of the document itself does not state a year or model.
