For the two lines that go to the tee, one on the left goes to the vacuum control (also called the blowoff valve, it is the big round can mounted between the upper and lower intake, hopefully you still have it). The one on the right goes to the warm up regulator.

The two that are at the top of the throttle body and capped go to the EGR valve on California cars, and are capped on others (EGR valve is often removed on California cars).

The line at the bottom goes to the thermo switch, and from the thermo switch to the distributor outside connection. This is what the thermo switch looks like:



The other line goes from the back of the distributor to the cut-off valve (electrical valve mounted on the upper intake, also often removed). The cutoff valve has a vacuum line that tees into the thermo switch vacuum line, and the other connection goes to the warmup regulator atmospheric vent (the line that connects to the air cleaner (also often removed).

On older cars it is hard to get everything connected back the way it was supposed to be because various components have been removed over the years.
