It's pretty straight forward, there's a mounting bolt and a adjusting bolt. bolt it off, un-plugg connections and That's that. When you put it back on, make sure you torque it down to the specs (not sure what it is on the prelude) but for the integra:
Mounting Nut (33 ft-lbs)
Adjusting Nut (17 ft-lbs)

Make sure the belt is tight or else you will get an annoying belt squeak.
