There is no wire from the ECU to the coil, [directly], the “IGN. INPUT SIG.” to the ICM, [igniter unit is the white lead, it is actually 2 white lead outputs from the ECU/ECM that connect together at some point in the harness before reaching the distributor assembly.

The primary output control from ICM to the coil is internal, [distributor assembly] 94
