OK. If I am reading this diagram correctly, it looks like I am eliminating a vacuum signal to the EGR system. I read references to the 3/2 switches before. Is this referring to a switch that signals a shift from 3rd to 2nd gear or am I way off. Does it all have to do with emissions controls?

I also read references to BB's. I am assumig this means literally BB's that you use in a BB gun because they are the right size.
