Right now you will be stuck on defrost I believe. You will need the 5 dollar check valve to split the heater and cruise lines.
^ this!!!

If everything's back started it up the fan was on when I started it and it had a little bit of roughness but smooths out Nash and it eventually shut off and kicked on when needed idles a little high but I think the TPS got knocked around when I move the plenum while it was off one thing I'm concerned about it's the front of the throttle body the bottom driver side there's a tube metal nipple she gets seal does not get sealed I've seen pictures with both any input thanks guys again thank you

Seems like it's "Vacuum Line Season" again in Vette-world. After looking at most of mine I have decided to replace most of them with bright green silicone rubber; it may look goofy, but at least I can see where they are and whether or not they're still connected properly. Now I need to figure out where is the best place to permanently connect a vacuum guage under the hood.I remember years back when lots of guys had an aftermarket guage under the dash for monitoring "fuel economy" (like you really needed it when gas was 28 cents a gallon...).

Don't give up over a minor wiring problem, just take a break. Lots of frustrations in older cars, particularly wiring and electric connections.
