Where do the three lines from the vac amplifier go? Manifold vac, CCEGR, and ? 76 Dart, supersix. Thanks.

One small-diameter line goes from the amplifier to the EGR valve.
One small-diameter line goes from the amplifier to the carburetor's venturi vacuum takeoff (located smack in the middle of the passenger side of the carburetor, not down low with the vacuum advance and PCV ports, nor up high with the float bowl vent port).
Large-diameter line goes to manifold vacuum.

The key is not getting those two small lines crossed up.

Isn't that one supposed to go to the temp switch then to the EGR so the EGR only activates after the engine is at operating temp?

Clarification, please. I noticed that Zorg's car is a 76 Super which is a 2 bbl., correct? The diag. title (and thanks for the source) shows a 1 bbl. Any difference? I am fixing a 77 Super that shows (on fender diag. and in place) that the 3 hoses on this car go to the manifold, the vac. reservoir,
and a small nipple low on the back of the 2 bbl. BBD. The larger nipple
center left has the vac advance hose (OSAC valve not connected due to
broken 'to carb' nipple on bottom.)
Thanks

Good point, I should've mentioned that I left the EGR control widgets out of my description since they vary per year, model and emissions package.
