The closest ECM I've found was by part number but it was not the exact number. The 2005 Lexus GS300 3.0L uses the ECM part number 89661-3F340 and you are looking for the 89661-3F330. So, there is a difference in the ECM here. It has the same 6 connector setup, but the only way to know if it is even remotely close to your ECM would be to try to match up the wire colors, wire location on each ECM connector, and where each wire goes. I searched for hours, and this was all I could find. This Lexus has a different engine number as well.
But I'm going to ask some other technicians if anyone can come up with this ECM pin out or diagram,
is your vehicle really a 2.0 liter V6? That liter size seems small for a V6 although I did see a 2.5 liter V6 which surprised me.
Also, can I ask what kind of issue you are working on? Are you getting a code for a specific sensor or circuit?
