Cranking is NOT related to the ignition wires.
Or rather, it shouldn't be.
Cranking is the Start wire. S2 (yellow) on the diagram. Goes from the key switch S terminal to the Starter relay terminal.
How the Starter Relay Works
Key in Start.
Power is available through the key switch (S) to the I terminal of the relay.
With the power now available at the I terminal, if the G terminal is grounded ( through the neutral safety switch if an automatic transmission), the relay is activated.
Activating the relay causes the battery stud to be internally connected to the solenoid terminal.
Power now flows to the starter solenoid.
