Technical Disconecting O2 wiring

[Paraman]

I would like to disconnect the wiring of my O2 sensor at the connector closest to the sensor. This is not easy to do as the connector is a tight fit after 12 years. There is a yellow tab on the female half. Do I push it, bend it or what. Anyone know?

Don't know about yours , but a lot of Fiat connectors you pull the yellow tab back out a bit and then squeeze the clip to release as the yellow tab locks it from releasing.
You may see another similar connector on the engine that is easier to look at to test what I said.

Part 1. Pull the yellow tab up

Part 2. Use a small screwdriver down its cavity to push the locking tab down

I will see if I can find an image on the internet

For now this is the best I could find

Of part 1
