Discoonecting oil Pressure switch connecter

[Qmyster]

Hello,
Hopefully someone can help, trying to change the oil pressure switch on a 6.0l v8 and I can't seem to disconnect the wiring from the connecter. I push the 2 plastic tabs in but when I try to pull on it it won't budge. am I doing this the right way?

they usually have little retainer you have to pull first

Look at the new one and make sure you are pulling the right bit.
Those connections can melt slightly and fall apart internally.
Good luck!
