On a 92 300 ce.
Is it plug and play or is it more to it.
My car does not have the check engine light, so i do not have to reset that.
Thank you.

The oxygen sensor is on the exhaust pipe near the back end of the transmission. The wires go through the floor into the cabin. There's a connector under the passenger carpet possibly behind a panel board. Undo the connector, push it through the hole, remove the old oxygen sensor, install the new oxygen sensor.
