If you can get your car in the air, do it... If not, then lay on your back and get your head under the front bumper right about in the center. Grab that big cross member you're just about to bonk your head on and pull yourself under the car until you're looking straight up at the front transmission. See that little unit attached by two bolts to the front underside of the transmission? It's about four inches long with a rubber boot on it's driver side end? That's it.
To make sure, it's got a bleeder valve the passenger side end (on it's upper surface); next to that is a hydraulic line (inlet); on the driver's end is the boot; and it contacts what looks like a switch that comes out of the tranny (there's a rubber boot at the base of that too, it's square).
Did that help at all?
When you find it, if it's wet...Replace it.
$59 from Ford, $62 from Mazda, $32 from AutoZone, NA from PepBoys, $42 from NAPA.
BTW: If you've already bled your clutch, where'd you bleed it from if not via the slave's bleeder valve?
