i had a crate motor put in but the guy never put my lines back on for my heater door to work.i had tpi and one went to the plenum and one to the heater control valve.i have a hose going from heater core to radiator,heater core to water pump.one hard plastic line has a elbow and one is straight.are both of these lines vacuum?where can i hook these these up in order for my heater door to work?

 

This sounds familure. Did we not cover this?
The straight vacuum line goes to a valve that hooks to the heater core hoses. since it sounds as if you no longer have that then block it off. The angled one hooks to the vacuum soure (manifold) and also "Ts'" off to the resivour. (And cruise control if you have that)
