Going off the picture in this thread I have swapped the black and the blue plug because they were wrong on my car. The vacuum gauge now shows 0, good or bad?

I cant find the brown plug? The grey one is currently where the brown one should be? But no sign of the brown plug or the place where the grey connector should go.

Coolant gauge shows 0 even though the car is warm.
