Ford Duraspark Ignition Module Wiring Diagram - Blue Connector Conversion

This document is a hand-annotated wiring diagram, credited to MustangSteve (http://www.mustangsteve.com), showing how to wire a Ford Duraspark ignition module (the version with the blue connector) to a 12-volt high-performance coil, starter relay, and distributor module. Gray lines represent existing vehicle wires, while red and green arrows indicate current flow in the START and RUN ignition positions respectively. Instructions include disconnecting the brown wire from the starter relay and the red/green wire from the coil, and disconnecting the pink (resistance) wire; a red wire is instead tapped at a plug approximately 4 inches from the ignition switch to provide 12 volts. The starter relay's "S" and "I" terminals are shown, with the brown wire routing and a note that 12 volts is present in "start" only. Wire colors from the Duraspark module to the distributor and coil are labeled: red, green, orange, purple, black, white, and red/blue. The diagram shows the firewall location and how the module connects between the ignition switch feed, the coil positive terminal, and the distributor pickup. A reader can learn the complete hookup for converting to Duraspark ignition, including which factory wires to disconnect and which module wires go where.
