Hans, the only two different things are the EVAP purge and vacuum lines.

Thanks Bryan, I'm aware of that one. Unfortunately it's a 90' not a 91'.

Re: Need a Secondary Vacuum Diagram fo a 91'
Never mind I found one! I forgot there's one in the engine supplement book.
For those of you not aware of the difference here are the two side by side. 91'+ on top, 90' on the bottom. H

Re: Need a Secondary Vacuum Diagram fo a 91'
one extra part is that the difference?
do you have a 1992? or is it the same as the 91?

 Oh...ya....I rotated each vacuum actuator for secondary so the shaft is not at such an angle  It appears they were installed 180 deg off.What I really need is a nice under plenum labeled picture of electrical connections as well as vacuum connections for a 91' like WB9MCW provided in http://www.corvetteactioncenter.com/...cuum+Diagnosis which appears to be other than a 91'
