What would one need to look for when trying to find a used PCM? I read somewhere the early style is different from later, but what else is different? Do you need to stick with the same model year? Same truck options? Find one with the same strategy? I’m guessing it’ll have to be reprogrammed to match the VIN of the truck it’s going in? I didn’t figure it’s just a plug and play deal.
