I just bought a Celica with a 2nd gen 3sgte swap. The car is running extremely rich. My first and only assumption right now is that its because the O2 sensor isn't connected. Looks like the wire snapped but I can't find where the rest of it is.

Anyone on here have pictures of where their O2 sensor comes from and goes? Is it all one wire? What color? Right now, thats what seems to be the main issue of the car.

it comes from the harness around the alternator. just look around, it cant be far from the o2 sensor.

Thanks. I had no idea it was a 4 wire plug. Just went to the local auto parts store and bought a new O2 sensor. Drives much better now. Just gotta workout a few bugs.
