I'm thinking the primary cooling fan is "controlled by the ECM" thru the Green Connector "C6". This provides a (-) signal to th Primary Fan Relay.

If you disconnect the Green Connector and turn the key to "ON", you can verify if the fan is being activated by the ECM or something else. If it runs with the Green Connector removed, it's not the ECM.
