    07-09 cobalt ecu pinout needed

    I need a pinout for a 07-09 Cobalt ECU 12597125 (E40 ecu i think) or a harness schematic. This may be in the wrong section so feel free to move it if need be.

    The closest thing we have is the 2005 Diagram and I think physically they're all the same: http://www.ecotecforum.com/forums/PCM/05cobalt22.htm

    correction... its an E37 ECM...

    what am i missing here??? Is there another part to the harness i dont have?

    Harness is a 07-10 g5/cobalt and ecu is a 07-09 cobalt. part number on the harness is a 20779795 and the ecu is a 12597125. Is this correct?



    dont freak out about the cut wires in the pic, that was me, i started to cut the harness down when i noticed the plugs dont fit the ecm

    PLEASE HELP

    I am curious to know what you found out on this matter. I am in the process of making a stand alone harness for a 08 Cobalt engine and have run into the same exact issue.

    Thanks for any replies
