WTF???
These are under the instruments. One of the 3 way deals is open (I understand that there are some "open" circuits) and there is an open hose!
There is NOOO way these were connected together because they won't reach. Kind of funny that all 3 of the lines are a kind of translucent white and the same diameter though...
The hoses to the 3 way come from the engine compartment and the open hose snakes it's way towards the center of the dash...
