Argh..MC pressure leak?

[Swoopy]

Howdy all.
Not sure of this part name. It is a sensor with 2 pins on front of master cylinder, red.
1995 B2300 2.3L 475k miles.
Found a Mazda site with part number 6640A.
Napa, advance, auto zone in my area don't have.
Called ford & mazda locally and waiting.

Anyone replace this part?
What size pipe plug as I'm thinking to go that route.
Been leaking for a while.
Mazda dealer a few years back looked at me, manager, and said Ididn't have the MC top tight. What a butt head.

I couldn't find that one in RockAuto.com.

You could grab one from virtually any modern Ford at the junkyard.

FYI, THAT switch was the subject of a Cruise Control recall. They leaked and caused fires in the Fords with Cruise Control that have power applied to that switch even with the ignition off. Any Ford dealer should be quite aware of that recall. They added a connector with a fuse in it to satisfy the recall. If the switch was leaking when the recall was done, they were supposed to replace it.

Doesn't appear to apply to yours.
