Default Know How to Remove O2 sensor connector from its Mounting Bracket?

Good day, trying to splice in a new front O2 sensor but cannot disconnect the end connector from the bracket it is mounted on. I broke off the rear sensor connector(the grey one) while removing it to get a better look at the one(green) I'm trying to remove.
Is there some trick to removing this thing?

I'm a little confused. Why are you attempting to disconnect the harness end if you only need to cut the wiring (leaving the plug end alone) and SPLICE in the new sensor into the existing wiring?

I could understand your situation IF you were replacing an entirely new sensor ASSEMBLY with the plug end already on it.

Which engine? 2.0 four banger?

Yes, it's a 2.0, 4 cyl. I was just trying to make life a little easier. Also, if by chance I am not able to unscrew the old sensor it would still be intact.

Thanks Max. I'll go ahead and work under the hood. Solder or Butt splice?

I gotcha'!

You think those connectors are a bear? You should try and access the V-6 ones. Nearly impossible. Read this thread if you've got the time...

Good plan on attacking the wiring first. I'd solder if feasible, but there are tons of aftermarket sensors running the roads with simply using the threaded fastener option. Make sure you use the proper special socket to remove the old sensor. That keeps almost all folks out of trouble. Pics of one in that earlier link if you need to see what it looks like.

PB Blaster soaking at least overnight may help. If not, running / heating up the sensor for a short period of time sometimes helps removal as well, just don't burn yourself on the hot exhaust.

Thanks for all the info, Max. Have been soaking the sensor with pb for a couple of nights already. Going to jump on this early saturday.
Thanks again.
