94 Chevy S10 Blazer vacuum problems

I recently bought a 94 S10 Blazer(4.3 vortec). The previous owner played around with the vacuum lines.:nono: Some of the lines are not even connected to anything. Can you possibly provide a vacuum schematic? The diagram that is supposed to be on the vehicle isn't there.
