Oxygen sensor plug I have just started cutting into my harness and ran into a snag. This is for a 2002 lq4. The front o2 sensor has no pink wire going to it. Here is what the connector looks like.
These are the wire colors going to the connector.
Purple/white
lt green/white
lt green
tan
The rear 02 sensor has a pink wire in it and it uses a square plug. Does this just mean that only the rear 02's are heated.

No, the front have a heater as well, they just use different colors than your rears do.
