make sure the vacuum hose is connected above the throttle plate.you prob'ly have it below, which would give it constant manifold vacuum.

i think thats right. i hook these things up wrong all the time. my worst is the vacuum modulator to the auto trans. i think it thru, and then invariably hook it up wrong, and it wont shift worth a crap. anyway, however that's hooked up, i hook it up the other way, and then it works.
