Two Ports ECU = Delphi ECU. This requires a harness with 2-plugs for the Delphi ECU
Delphi Electronics have also changed, so to be safe get parts for 2014+ onwards
2008 – 2012 = Daewoo & Sentec ECU = Not made anymore and very very very difficult to find and fix!
So i would advise to upgrade all electrics to 2014+ model including harness , and you will find these parts on EBAY USA (It’s a big 250cc market)
