I need to get the vacuum door locks working again. The yellow line to the drivers door is broken so that's most likely the culprit. I can lock the rears and they immediately push the front locks up so I bet the system is relatively leak free.

But in the engine compartment off the yellow vacuum splitter thing there should be which color lines?

I have the yellow blocked off and plugged into it is a green with yellow line and then there is a yellow with red just chilling not connected to Anything.

Can anyone advise on what should be where?
