As your facing the front of the car on the left side of the engine look for two wires, the yellow/orange one is before the cat and the gray is after the cat.

Or are you looking for the wire to hook up a gauge to? If so the stock sensors aren't wide band if that's what you're looking for

No, you need to keep the stock one for the car, you can have a shop weld a bung for one in fairly cheap though.

Bosch, ngk, aem but I'm not sure aem sells it without the gauge.

Getting a wide band gauge with the sensor may be cheaper though

aem makes a UEGO and Innovate Motorsports makes a few options, all of which are quality products. All of the Innovate and the UEGO widebands are compatible with RomRaider in addition to other tuning programs. If you buy the sensor alone, you will need a way to power and control it.
