lift up the drivers side behind the front tire with the tire jack, and you'll see the modulator sitcking out the side of the tranny on the drivers side, about parallel with the tire jack when you're lying on your back under the car. Modulator is either blue or red plastic and has a black cap and a tube to attach the tube from the vcv.

Somebody has probably posted pics and everything about this on the forum. Have a ssearch.
