Plastic Vacuum lines diagram needed?

Okay, my jumbled chaos of a car does not appear to be right even remotely according to this. It all started with a random temperature gauge spike and the heater quick working car started to overheat my wife started playing with the defrost/heat/vent/ac/bi-level switch and weirdly heat started to blow and the temp gauge went down no more problems for about 10,000 miles then it started again same scenario heat stop blowing warm air and cat overheat. Play with the switch and hit and miss sometimes it works sometimes it don't then that stopped, and it just overheats bad now. Well I changed the thermostat, water pump, noticed a crack in the plastic of the radiator on driver side below the hose so changed the radiator, the engine coolant temp sensor, intake manifold gaskets noticed the intake manifold was cracked so replaced it, now it don't read hot and the heat started working but boy dose it overheat and build mad pressure so I hallowed out the catalytic converter and that helped a little but I will occasionally see damp spot in passenger floorboard but not often and get that smell so heater core is next. But on those vacuum lines they don't connect like that I'll upload a diagram of what is actually there in the car connected and add pictures. I appreciate any help and advice.

Okay, this is a better diagram of what's going on there but if you noticed the vacuum that says transmission and the one that says accessory are not hooked up to anything.
