Alright, here's the situation. I am replacing my O2 sensor. I bought one that is from DENSO. Its obviously a 4-wire sensor, but the wire colors are different. Its a splice into the old sensor deal.
The new sensor has 2 black, 1 blue, and 1 grey wires.
What are the colors of the stock sensor and how do they correspond to the DENSO sensor?

I'm not sure on what colors do what on your new sensor, but maybe google search it and see what you can find..did it come with a wiring diagram or anything? As far as the stock 02 goes, going off of memory here, so somone may want to verify:
White: o2 signal wire White: heater power wire Grey: heater ground wire black: Ground wire
You will want to use a digital multimeter and find the correct white wire..One of the white wires should see power when the key is turned on, and when the car is started, one of the white wires will cycle voltage between .28- .88 or something around there..that wire is the o2 signal wire. Maybe this helps, maybe it doesnt

Here's our O2 harness:
White-Black = Signal Black-Green = Signal Ground Black-Red = Heater Power Black = Heater Ground
If I'm not mistaken, the O2 is like this:
Blue = Signal Gray = Signal Ground Blacks = Heater Wires
Hook it up like this:
White-Black => Blue Wire Black-Green => Gray Wire Black-Red => Black Wire Black => Black Wire
But, make sure your blue wire is the signal wire, most are. The paperwork that came with the O2 should say that it is. If not, put the O2 in, leave it unhooked, and test it with a volt meeter.

THANKS!!
What I meant by the paperwork was it *should* say which is the signal wire. I went through several days, and coountless hours toying and testing to finally figure it out.
Let me know how it works...
