    GM E46 Pin Out's

    Hi all,
    I have one of the new Duramax 3.0L Diesel engines with GM's E46 ECU.
    Im looking to build a bench harness but can't find the pinouts anywhere.

    Anyone have any details they can share?
    Thank you all for your help.

    You're asking for information on an ECU on a forum that the company which hosts the forum doesn't support?

    Jokes aside, anybody that has that information would be spending hundreds if not thousands of dollars a year for it, just to hand it over to you?

    If you want the information, you can purchase a GM SI subscription here:

    Thank you for that info on the GM subscription. I hadn't found that on my travels.
