What years does this sealed-bowl distributor diagram cover?

The document is titled '92-96 Sealed-Bowl Distributor and includes year-specific ignition schematics for 1992 (Push-Start D), 1993/1993½ 5.0L CCD H, 1994, 1995, and 1996 CCD H gasoline systems.

What is the ICM connector pinout for the closed-bowl TFI system?

For System D (gray ICM): pin 1 PIP (Gy/Or), pin 2 SPOUT (Pk), pin 3 START (R/LG), pin 4 COIL− (Tn/Y), pin 5 ICM PWR, pin 6 GND (Bk/Wh), with TACH on Wh/Pk. For System H (black ICM), pin 3 is IDM (R/LG) instead of START, and ground is Bk/LG or Bk/Wh.

What fuse powers the TFI/distributor ignition circuit?

Each year's schematic shows a 20A fuse in the Engine Compartment Fuse Box (page 13-5), labeled HOT IN START OR RUN, feeding the 16 R/LG power circuit.

What does the ignition control module (ICM) do according to this diagram?

It receives the SPOUT (or PIP and SPOUT) signal from the PCM and uses it to switch current on and off in the primary circuit of the ignition coil; without the SPOUT it runs on the PIP at base timing.

How much voltage does the ignition coil produce per the diagram notes?

Each interruption of the primary current makes the ignition coil secondary circuit produce an open-circuit high-voltage pulse of up to 40,000 volts, transmitted to the distributor on the coil wire.

What is the ignition suppression resistor part number shown?

The 1992 and 1993 schematics show a 22KΩ ignition suppression resistor, part number E90B-14A601-EA.

This document is a multi-panel Ford reference sheet covering the 1992-1996 sealed-bowl (closed-bowl) TFI/CCD distributor and its ignition wiring. The top-left panel shows exploded assembled and disassembled views of the sealed-bowl distributor, labeling the shaft, screws, rotary vane, Hall effect vane stator switch (Profile Ignition Pickup / PIP), octane rod, rotor (with a note to coat the rotor blade tip with 1/32" silicone compound), O-ring, gear, pin, and base assembly. Two breakout-box connector diagrams cover System D (remote-mounted closed-bowl, push start, gray ICM) and System H (remote-mounted closed-bowl, Computer Controlled Dwell, black ICM), giving ICM pinouts, CMP/PIP sensor pin numbers, test-jack numbers, and wire colors (Gy/Or PIP, Pk SPOUT, R/LG, Tn/Y coil−, Bk/Wh ground, Wh/Pk tach). Five year-specific gasoline schematics (1992 Push-Start D, 1993/1993½ 5.0L CCD H, 1994 CCD H, 1995 CCD H, 1996 CCD H) show full circuits from the PCM/EEC module through the SPOUT check connector, ignition control module, distributor ignition shield, radio capacitor, ignition coil, and 20A HOT-IN-START-OR-RUN fuse feed, with circuit numbers (395 GY/O, 259 O/R, 570 BK/W, 648 W/PK, 938 BK/LG, 929 PK), connector IDs (C1021, C1019, C1008, C1017, C101, C178), and functional callouts. A reader can trace TFI ignition wiring and identify distributor components for these years.
