Heater hook up

I bought my 79 vette in August and have just about repaired everthing on it that was bad. However, the air conditioner and heater was never hooked up. It looks like all the components are there. I don,t know where to start to get the heater working, and It's to cold to drive without it.

Never hooked up is too broad of a discripion to start. It was hooked up new, what was unhooked? Fill us in a bit and we may be able to help.
