93 ford 350. What the heck is this and how is it done?

Is there a connector for a pressure differential switch on the front
end of the master cylinder?
It's shown on the Aerostar in my 1991 service manual.

there's an electrical *connector under the middle of the plastic reservoir.
The reservoir feeds both the front part of the master cylinder and the rear
part. I didn't try very hard, but the connector doesn't want to come apart.
