Thank you Overboost.

So I was trying to remove the rain sensors from scrap vehicles. They do come off very easy if you pry with something from behind.

Basically if you're not changing the glass, you will need the backplate, or whatever it's called. It's easy to remove with the sensor as one piece.

Now if you have a new glass with the first plate pre-installed, you just need the sensor.

For the life of me I couldn't figure out how to separate them and I thought they just clipped in.
After breaking a few tabs I figured our how it works lol.
To separate them you gotta push on 2 tabs, one by one. Then the backplate plastic glass will be released.
I decided to take a few pictures so that whoever wants to separate them doesn't break the tabs by accident

I will be installing the sensor tonight, can't wait to test it out!
Also picked up heated rear seats while I was at the junk yard lol!
