Name the part located underside of the master cylinder

Looks like my cars ABS is out, and probably 'cause of this part. I dont know the name of the part. I heard it might be called the "pressure switch-its located under the master cylinder its a plastic black cylinder-with 2 wires attached to it" . It seems like thats is where the brake fluid is leaking, from what my mechanic tells me. Can you name this part? I cant even find a part no.

I'm not too sure on what it is called but I had it leak on my 1995 ATX before. I believe it is used in the cruise control circuit and maybe ABS by detecting brake fluid pressure.

When I couldn't get outta park, Sho-N-Go said that plug was called the "cruise control deactivating switch". It had filled with brake fluid and shorted out the #1 fuse. I unhooked it and all was good again.

Yes, the switch is the cruise control deactivation switch for the ATX cruise control. It is a backup and cuts out the cruise control in case the brake pedal mounted switch is not working. I just replaced mine - it was about $18 from the Ford dealer. Just unplug the wire from the bottom and unscrew it. The fluid will just slowly drip when you take it out, just put a rag under to catch the drips. The hardest part was getting a crescent wrench on it with all the wires and hoses packed around that area, I removed the transmission dipstick and that made it easier (but then again I also changed my rear oxygen sensor from the top of the engine!).

The switch on my car is only for the cruise control. The wiring goes directly from the fuse panel, through the switch, and to the cruise control servo - no ABS.
