ECM Part number needed

[Ser-Fed]

Hi!Please somebody help me to determine the correct part number for the Engine Control Module for my '07 Vibe (2WD, non GT). Unfortunately for me there is no local GM dealership which could professionally manage with US-market cars. They only can order parts with given part numbers.VIN : 5Y2SL65837Z422593There is a Toyota number on the old one: 89661-02K40Gurus, please help!I'm stuck with it.

I found out that it should be one of two following parts: 19184259 or 88974696. The difference is that 88974696 is "1st design" and 19184259 - "2nd design" according to GM Parts Catalogue.Who could tell me what does "design" mean? And which one of two I should order.Thank you.
