Note: I am not sure if the D series IAC hooks up the same way a B series does.

Anyway, for a B series one line runs to the nipple on the bottom of the TB and the other runs to the back of the engine as shown here:

Notice the coolant line running from the IAC to the coolant passage on the back of the engine.
