Broken front brake pad sensor connector

Hi all. I’ve broken the front brake pad wear sensor on the loom. Looking at this great forum it says to fit connector part 1J0973802. All straight forward so far. But, that part connector has two pins and the wire on the loom looks like it’s four wires. I only noticed this when it broke and I could see what looked like four pins. Unfortunately I didn’t take pics. I managed to temp put it back together so didn’t want to pull it apart any further. 
So does anyone know which wires on the loom connect to the connector, or is it all oblivious once I take that connector apart?

Thanks in advance.
