Does anyone know what the difference between these two emc's? Can anyone direct me to an EMC site that lists all the part #s.

I have heard that other GM vehicles get the same emc's as the 3rd gen cars do, is this true.

I am going to start to burn my own PROM's, but I need to research all of these questions first.

thanks in advance.

 

What!?
No one on these boards know this?

Not even a link to a site that would have this information.
