Which Duraspark module does this diagram cover?

It covers the Duraspark ignition module with the blue connector.

What voltage does the pink resistance wire carry?

The pink resistance wire carries 6-9 volts.

Which wires are hot with 12 volts only in the "start" position?

The Brown wire from the starter relay "I" terminal and the Red/Blue wire are labeled '12 volts in "start" only.'

What wire colors run between the distributor module and the Duraspark module?

Orange and Purple wires connect the distributor module to the Duraspark module, with Black also shown at the module; Green and White wires are also labeled at the module.

Where does the 12-volt red wire connect?

The red wire connects to a plug approximately 4 inches from the ignition switch and is hot in the Run and Start positions.

This document is a hand-drawn/computer-drawn wiring diagram, credited to 'MustangSteve' (http://www.mustangsteve.com) and hosted via WWW.FORD-TRUCKS.COM, showing how to wire a Ford Duraspark ignition module (the version with the blue connector) into a vehicle. It depicts the starter relay with its "S" and "I" terminals, the ignition coil (with + and - terminals), the distributor pickup module, and the Duraspark ignition module. Wire colors are labeled: Brown (12 volts in "start" only, from the starter relay "I" terminal through the firewall), White, Red, Green, Orange, Purple, Black, and Red/Blue (12 volts in "start" only). The diagram notes a Pink resistance wire carrying 6-9 volts, and a 12-volt Red wire 'to plug approx. 4" from ignition switch' with Run and Start switch positions. A legend indicates that gray lines represent existing wires, and colored arrows show current flow paths for START (red arrows) and RUN (green arrows). A reader can learn which Duraspark module wire connects to the coil, distributor, starter relay, and ignition switch circuits, and which circuits are hot only in the "start" position versus "run."
