2003 2.3 auto to manual swap - ecu question

I almost have all my parts to convert my 2003 2.3 to a manual transmission. Now I'm trying to find the ECU. On the Zetec write ups, the ECU required changing the entire harness, but I've only been able to find a few posts specific to Duratec.

Will I need to swap the complete harness when I swap the ECU, or only the transmission harness?

Also, does the Duratec ECU code have to match, or will any manual 2.3 ECU from 03-04 work?

Thanks,
Mike

No takers on what wiring needs to change when I switch from an auto to a manual ECU?
