What part number is the ignition suppression resistor in the 5.0L ignition system?

The diagram identifies the ignition suppression resistor as part E30B-14A601-FA, wired between circuit 11 T/Y and ground G201.

What are the terminals on the Ignition Control Module (ICM)?

The ICM (solid state) shows terminals IGN GND, PIP, SPOUT, START, COIL, and TFI POWER, with the distributor connected to it.

What wire supplies 12V power to the ignition control module and coil?

Circuit 16 R/LG carries 12V in START/RUN through splice S132, feeding the ICM (via C1012), the ignition coil (via C131), and the PCM power relay (via C293, page 24-1).

Where is the SPOUT check connector in this circuit?

Connector C1009 is the SPOUT check connector, located in the 929 PK circuit between the ignition shield/PCM wiring and the ICM SPOUT terminal.

Which pages cover the related PCM and starting system circuits?

The PCM is covered on pages 24-2, 24-3, and 24-4; electronic engine control on page 24-4; the starting system on page 20-1; the instrument cluster on page 60-2; and the PCM power relay on page 24-1.

AI caption April 2012 · Photo 17 of 54

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.
