    Any 12200411 PCM will work. It doesn't matter what it comes out of,you will be tuning it anyway. You should be able to get the two 80 pin connectors with a few inches of wire on them at a U-Pull type of junkyard. You only need a few of the pin terminals to do the swap. You want the connectors with the Blue and Red plastic pieces on them. The 2002 Chevy Express Van seems to be the most popular tune file to start with. Remember the truck will not run until you disable V.A.T.S. from the tune or do the V.A.T.S. Relink procedure---Which I have never done.
