Bed removal on mini

Hi, I’m working on removing the bed on my mini and it looks different than all the youtube videos. I’m having problems removing the red wire from the machine to finish taking the bed off. I can’t find the ‘tab’ all the directions tell me to press to remove the red wire. Can you help? I’ve attached photos of the section that’s giving me problems. Thanks!

That top picture shows the connector block, it’s just back in the cable chain a bit and upside down. flip that bit over and you should see the latch. It’s the black plastic tiny rectangle looking thing.
