4 wire O2 sensor

[roachjuice]

so i have read this whole thread and still don't understand what you hook this sensor up to. like what im getting is if your converting a one wire to a four wire o2 then you need to wire up some shit. ok so the signal wire is the black one which you hook up to your stock harness then take some wire to one of the white wires, ground it and take another wire on the same white wire and hook it up to a power source? wouldn't that **** some shit up? i have a 3 wire setup in my omni now and all i have hooked up is the signal wire. i need to know where to hook up the other 2.

The final word, as I understand:

The white wires are for heating the O2 sensor. One is 12v and the other Ground. Doesn't matter which goes to what, just make them 12v and Ground.

The black wire is the signal wire that feeds the information to the computer. I assume if there are single wire O2 sensors, than this must be that same wire.

The additional grey (or 4th) wire is a seperate ground wire. This is supposed to help with a better or proper reading in relation to the signal wire.

sweet action. so both my whites one is ground and the other 12v. easy enough for me.
