How does this reconnect?

View attachment 395241 View attachment 395240 I’m replacing my vacuum switch for my heater and a/c controls. It fell apart in the dash and so I didn’t get to see where everything was connected beforehand. Now I’m putting everything back together and I’m a little puzzled. There’s a blue cable and a yellow(?) cable that need to be connected and I’m not sure which one goes to which connection point. Please help! View attachment 395239
