Question Help - which PCM is which

Alright peoples
throwing a hail mary pass here

So I'm putting my car back together and I'm getting ready to have the base tune uploaded

My issue is I have 3 PCM's and like an Idiot i didn't write on each of them what car they were out of
How might I be able to tell which is which with out plugging everything back together to find out its the wrong one

thanks in advance

Nick

I don't think there is any way to tell beyond reading each when plugged into the harness.

At least not for us mortals. :-)

I'm sure all those numbers mean something, but haven't heard of any sort of master list for de-coding them
