Brake wear sensor

[Macmain12]

Can anyone tell me which wire , red or yellow goes to what terminal on the new plug I've bought . 1 & 2, is marked on the plug. Looking at how it works does it make a difference it makes a continuous circuit when pads are worn.

pad wear sensors have no polarity, either way will work, theres either continuity or not
