1995 Ford Bronco 5.8L Engine Controls Wiring Diagram - PCM, Injectors, IAC (25-2)

This document is page 25-2 of a Ford factory-style wiring diagram (EVTM format) covering the Engine Controls system for the 5.8L engine. It shows the 12V relay-energized power feed (circuit 361 R) from S136 on page 25-1 through connectors C101M/C101F and splice S149, continuing to C180 on page 25-3. Components diagrammed include the Secondary Air Injection Bypass (AIRB) solenoid (C1022), Secondary Air Injection Diverter (AIRD) solenoid (C1023), EVAP canister purge valve (C171), Idle Air Control (IAC) valve (C1007), and all eight fuel injectors (C190-C197). Descriptive callouts explain each component's function, such as the IAC valve controlling idle speed via PCM duty cycles and the injectors metering fuel at each intake port. Control-side wires (190 W/O, 200 BR, 101 GY/Y, 264 W/LB, 556 W, 555 T) route to numbered pins on the solid-state Powertrain Control Module (PCM). The bottom of the page shows PCM pinouts and circuits leading to the All-Wheel Drive system (784 LB/BK, page 34-1), the Vehicle Speed Sensor (679 GY/BK, 678 PK/O, pages 64-1), and nine wires to the E4OD transmission (pages 30-1, 30-2), including 925 W/Y, 315 P/O, 237 O/Y, 924 BR/O, 923 O/BK, 480 P/Y, 199 LB/Y, 911 W/LG, and 224 T/W.
