Edelbrock Throttle Linkage?

[muddpile]

I am putting an edelbrock 600CFM electric choke carb on my 72, and can't figure out how to hook up the throttle cables. There is the one that goes to the gas pedal and the other one that goes to the tranny (TH350). Where and what do these cables hook to. Also, what is the inlet on the back of the carb on the bottom middle? On my Q-jet it was a kinked off metal tube, and on my Edelbrock its a short stub of metal tube. The PCV is on the front in this location, but what is the back? Thanks!
