02 sensor wiring

[hardhead]

I bought a set of bosch universal 02 sensors since my harness was missing the sensors and plugs. My question is how to wire them up? They have four wires,instructions say 1 signal, two heater wires and a ground. The pinout describes my wires as low signal,high signal,heater low control, and the other is the power wire. I believe the low signal will be the ground but I'm not sure of the others. By the way we fired it up today without the 02 sensors and it popped right off but the DBW did not respond. Any ideas what to look for on this too?
