HVAC Vacuum line color codes?
 
Hey does anyone know which vacuum line goes where on the HVAC box? I am replacing the evaporator core, at the point where im putting the box back in the truck.

My problem is I took all the little vacuum lines off the box, and now I need to know which color goes where. I saw in a video the yellow one is on the drivers side of it, that's all I know.

I'm only assuming your truck is the same as mine. I have a 2001. Brown and red go to the vacuum motor 2nd over from the drivers side. red going to the metal longer "port". Brown going to the shorter plastic "port". Green goes to the passenger side motor and black back through your firewall with the A/C lines.

Thanks for the help, I am left with a brown one, where is the plastic port? I only have 3 actuators with metal ports, leaving the brown one un used? I put the yellow one on the left side for the front vents, and red for the floor actuator, and green on the passengar side like you said, and the black one goes through the firewall, but im left with a brown one now.. Ive been installing the metal frame of the dash but i cant go any further until i figure out that line. Also the wiring is not fun.

There should be another port on the floor one. Where you hooked up the red one. There should be 2 ports on that one.
