Brake pressure switch function ?????

OK, 96 S10 4.3 5 spd. The brake pressure switch on the proportioning valve is a one wire switch. How does it work? Is it open all the time and then close to ground when there is a problem? Or the opposite, Closed to ground all the time and then open up when a problem pops up?
Reason is I have deleted ABS, and added a Wilwood adjustable proportioning valve. It has a 2 wire pressure switch on it and I am trying to figure out how to wire it into the factory system.
Should I cut the connector off the factory wire and connect it to the 2 wire switch and then the other wire to ground?
Thanks in advance.
