Ford Duraspark II Breakerless Ignition Wiring Diagram - Primary & Secondary

This document is a pictorial wiring diagram of a Ford breakerless (Duraspark II-style) ignition system, showing the physical components and how the primary and secondary circuits interconnect. Components illustrated and labeled include the ignition switch, a terminal connector, the primary resistance wire, a quick disconnect, the starter relay, the battery (with positive terminal and chassis ground), the oil-filled ignition coil, the amplifier module (ignition control module), an in-line connector, the breakerless distributor (shown with cap removed and installed, with its own ground), and a spark plug. A legend at the bottom distinguishes line types: a heavy solid line indicates the primary circuit (battery, ignition switch, resistance wire, module, coil primary, distributor pickup) and a dotted line indicates the secondary circuit (coil tower to distributor cap to spark plug). A reader can learn the overall layout and routing of the ignition system: the primary feed passes from the ignition switch through the terminal connector and primary resistance wire (with a quick disconnect) to the coil and amplifier module, while high-voltage secondary current runs from the coil to the distributor cap and out to the spark plugs. No wire colors, part numbers, resistance values, or model years are given.
