Really quick question

[cardudeusa]

I tried the search but couldn't find the answer I need. Which wire on the O2 sensor goes to the PCM. Thats all I need to know. Thanks.

The wire that has the low resistance between the wire and the body is the heater wire (on a two wire sensor) so the OTHER wire is the one you need.

On a three wire (2 whites and a black) the blalck one is the one you need.

I actually found instructioins on autometers website. If I had used the oxygen sensor pigtale you were right. But I tied into the actual car harness. It was on the driver side and a blue wire with a green stripe.
