When buying an ECM, is it safe to buy a used computer, if so, what do I need to be sure of?
I'm seeing a refurbished one from a reputable online site for $300, which they're saying it's a plug in and go/reprogrammed.
But I'm seeing a used one for $60, that's showing will run for my exact truck. Is there something that I need to match up to be sure?

Thanks.
