One goes to into the thermo valve on the underside of the manifold, and one comes out and goes to the EGR valve. With a Weber you don't need the EGR valve or need it connected (can use as a block-off, or make your own). The thermo valve doesn't need to be connected at all then.
My own Weber/system looks like Earl's photos, except not so neat and clean. Except my brake booster is neater lookin' than Earl's, his needs painting. I also have the heat shield over the exhaust manifold on mine. I also have a taller air cleaner.
I hope you bought good-quality caps, the vacuum caps from AutoZone or O'Reilly only lasted a few months, so I went back to vacuum tubing blocked off with wooden golf tees. I haven't tried NAPA or CarQuest vacuum caps yet.
