Replacing my PCM, 2002 8.1, where do I find it?

Getting a tuner from BlackBear, probably Thursday.
On the 6.0 they say it is under/behind the battery, also where my window washer tank is located.....
Is that the location on mine?
Again, 2002 Silverado 2500HD, 8.1.....
I just came back from doing more checking and there is something just to the left of the battery under the radiator hose.....Might that be it?

Thanks for any info.
  • I never did find that link when I was searching. VERY vague pictures but yes, I think I know where it is now.
    Looks as if I remove the support, pull the battery and then it is fairly easy to pull/remove.
    I searched for how to pull it but never found a thing. Not even on youtube.
