O2 Sensor replacement
 

Hey all,
My upstream O2 sensor on the driver side is shot and I am attempting to replace it myself. (Not a mechanic at all, pretty new to doing self maintenance as well.)

I was able to get the actual sensor off and out of the cat, but i'm struggling with getting the wiring harness disconnected.

I pulled up the white tab, and that's about as far as I've gotten with it. I don't have much room to look around and see if i'm missing something.

Is there another piece holding it in that i'm missing? Or is it just the white tab and that its stuck?

Thank you!

Figured id add a pic just incase it helps at allhttps://i.imgur.com/Y8ROvnR.png

Update: incase anyone gets in my situation. I pushed the white tab out, and then with a tiny flathead screwdriver, i pushed the middle of the white pin inwards and that released the o2 sensor from the wiring harness. Not sure thats the proper way to do it, but it worked for me.
(Sorry for thread bumping)
