Got a picture? It could be the front pressure sensor for the ABS. Post a pic and the wire colors please.

Yep, that is the front pressure sensor for the ABS system. Your replacement is for a vehicle without ABS on it.

Cool, thanks. Hopefully, the master cylinder is what it needs since pedal sinks. Booster is good as it holds pressure when I turn it off then goes down when I start it.
