1993 Ford Mustang 5.0L Ignition System Wiring Diagram (Page 21-3, TFI/ICM)

This document is page 21-3 of a Ford factory-style wiring diagram set, showing the Ignition System for the 5.0L engine. It illustrates the circuit connections between the Powertrain Control Module (PCM, pins 20, 4, 16, 56, 36, 30), the Ignition Control Module (ICM) with its solid-state terminals (IGN GND, PIP, SPOUT, START, COIL, TFI POWER), the distributor, and the ignition coil. Key components include the ignition suppression resistor (part E30B-14A601-FA), the ignition shield surrounding the PIP/SPOUT wiring (circuit 929 PK), and the C1009 SPOUT check connector used for timing adjustment. Wire circuit numbers and colors are labeled throughout, including 57 BK (ground to G201), 11 T/Y, 259 O/R, 929 PK, 395 GY/O, 199 LB/Y (to electronic engine control, page 24-4), 32 R/LB (to starting system, page 20-1), and 16 R/LG (12V in START/RUN feeding the ICM, coil, and PCM power relay via connector C293, page 24-1). Connectors C234, C1012, C110, C250 (instrument cluster, page 60-2), C131, and C293, splices S102 and S132, and ground G201 are identified. The diagram cross-references related pages 24-2 through 24-4 for PCM details, making it useful for diagnosing TFI ignition, no-spark, and SPOUT timing issues.
