    I just looked up that PCM and it looks just like the 0411 which the Roadrunner is...

    thats all I thought there was to it, thanks!

    as for the RR 0411Vs V6, they are the same case, but the chips are not in the same place on the inside.

    for your viewing pleasure, it's now a table, showing a couple of the main pinouts I've used to create this.

    still working on it, added the "0411" for shits and giggles, and also added in the L67 pinout. next will be the 99-02 firebird, it should be a little different, as it uses DBW. we'll see.

    ok, worked out a couple of typo's in the original chart, and added the 2002 firebird pinout. I also removed the 0411 from the original and created a second chart specifically for it. Next project will be to trace out all of the generic pin listings to get better definition.

    It's not easy to format like that in the forums, nice work!

    You know you can upload spreadsheets here if that is easier for you to work with...

    funny you would say that, I made a table in open office, then just did the old copy and paste. it works here, but not on any of the other forums I'm on.
