Well, now that I think about it, it *may* just be a matter of getting stock linkage and plugging into vacuum hoses, but you may have gone through a de-smog from with of varying ability.
I am not sure what year your Pig is, or how serious they take emissions inspections where you live, but it may be a hassle if you have to go from 0 to full enchilada on emissions equipment and vacuum lines...
