Where is the o/s and pcm ID stored in a black box vortec pcm? I can find vin, but the structure is much different then ls style pcms. I have the pcm id from the sticker on pcm, as well as hpt reads most of it out(2 digits it replaces with # for some reason), but I cant find it in the bin. Same with the o/s, does not appear to be in the bin. Anyone played with these much?
