02 sensor wiring
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?

Re: 02 sensor wiring
(stole this from an online manual)
Cable colour allocations for the Universal Oxygen Sensor are as follows, sensor output signal wire = black, sensor heater element cables = White ( Note - heater is not polarity sensitive ) Sensor signal ground ( where used ) = Grey

Re: 02 sensor wiring
Thanks but I'm still not sure about how to wire it. The tan wire in my harness is low signal which I'm told would be the ground. Where does the hot wire,pink, go?

Re: 02 sensor wiring
Not sure if this will help, im getting into the wiring of the LS also so its kind of new so far.
Edit, sorry for the side pic, i rotated but its not wanting to keep it that way for some reason.
