ECUs changed in September 2004 for the 1.4 8v engine.

I don't know the difference between the 2 you show and have never had a chance to try different ECUs (as a kit) in the cars.

There were several versions of ECU for different regions and specifications of fuel and emission control, some even didn't have the EOBD diagnostics installed.

If your donor ECU comes from the same country and before September 2004, I would think you have a good chance the engine will run, but getting the right ECU would be the best chance to get it working correctly.
