Which 02 sensor from Cats-Direct and how to wire in?
 

I have done a search but couldn't find the exact answer I'm looking for.

I've an MY00 Impreza and want to get a 02 sensor from cat-direct. Am I right that its the 3 wire sensor I'm after.

Also can someone tell me which wires I have to join with which wires on the OE connector?

TIA

Yup, it's the 3 wire one.

IIRC the sensor comes with a little guide (and all the bits) to tell you how to fit it, it's not to difficult anyway there a 2 wires the same colour (white I think) which is for the heater and another one on it's own (black I think) which is the signal. Although I don't believe it's the same colours on the stock unit it's easy enough to work out.
