By the sounds of it, the lambda sensor you have bought is a universal jobbie and in my experience, they don't last very long. On my old scoob, I had aair/fuel ratio meter on my water injection system and I used a universal one, had to replace it every couple of months!
The black wire is the signal and the white wires are for the heater to warm the lambda sensor when the engine is cold
