Brake Pressure Switch ?? Need A replacement

With my upgrade now to the Wilwood MC and the Wilwood proportioning valve the stock pressure switch will not work, it is different threads. The Wilwood prop valve comes with a switch to activate your brake lights but I haven't found enough info as to whether it would work as the idiot light, its also a 2 wire instead of a single wire. What switch are others using when going to a different style - I have not anything found here on the site and googling hasn't gotten me anywhere, below is the stock switch, thread on the new prop valve is 1/8"X27 npt - not sure what this even is. Car is a 69 dart GT, original all manual drum brakes, not sure if the stuff in the car is original or not
