Ford Duraspark II & TFI Ignition System Wiring Diagrams - EEC-IV PIP/SPOUT

This page (23-01-2, "General Ignition Service") from a Ford service manual presents two labeled ignition system diagrams. Figure 1 illustrates the Duraspark II ignition system, identifying the ignition switch (with RUN, START, START BYPASS circuits), ballast resistor, coil with BAT and TACH TEST terminals, distributor cap, rotor, adapter, spark plug, starter relay, battery, distributor, and ignition module (drawing B4097-2A). Figure 2 illustrates the Thick Film Integrated (TFI) ignition system, showing the distributor cap, rotor, adapter, spark plug, RUN and START circuits, the "E" core ignition coil, starter relay, battery, EEC-IV module with INPUT (PIP) and OUTPUT (SPOUT) signal connections, a connector, and ignition ground (drawing B4281-2B). A reader can learn the overall component layout and wiring relationships of both Ford ignition system types: the older Duraspark II system with its ballast resistor and separate ignition module, and the newer computer-controlled TFI system in which the EEC-IV module receives the PIP (Profile Ignition Pickup) signal and outputs the SPOUT (Spark Output) signal. Mirrored bleed-through from the reverse page (a section index for Section 23-01) is visible but not readable in detail.
