Which engines does this capacitor installation diagram cover?

It shows capacitor-to-ignition-coil installation for the 5.0L (MFI), 5.8L (MFI), 4.9L (MFI), and 7.5L (MFI) engines.

Are there special conditions for the 4.9L engine illustration?

Yes — the 4.9L (MFI) diagram applies specifically to engines with a 75 amp alternator and manual transmission.

Where does the RFI suppression capacitor mount?

According to the illustrations, the capacitor assembly is installed onto the ignition coil assembly on each engine.

Does the document identify the numbered callout parts?

No, the drawings use numbered callouts (1–7), but no legend or parts list defining them is visible on this page.

This document is a scanned Ford service illustration (figure code K20720-B) showing the installation of an RFI (radio frequency interference) suppression capacitor assembly onto the ignition coil for four different MFI engines. Four side-by-side line drawings depict the capacitor and its mounting/wiring at the coil assembly for: the 5.0L (MFI) engine, the 5.8L (MFI) engine, the 4.9L (MFI) engine equipped with a 75-amp alternator and manual transmission, and the 7.5L (MFI) engine. Each drawing includes numbered callouts (1 through 7 across the set) pointing to components such as the capacitor, coil, mounting bracket/hardware, and wiring connections, though the legend defining these numbers is not included on this page. A reader can learn where the suppression capacitor mounts relative to the ignition coil and how the routing differs among the 4.9L, 5.0L, 5.8L, and 7.5L multiport fuel injected engines. The scan contains no year range, torque values, or part numbers, and is likely one page of a larger service procedure.
