Vacuum Line Question ('86-'90 RC)

Hey anybody, it's a 1990 Ramcharger with AC. I have two hard plastic vacuum lines coming out of my firewall right next to the heater core hoses, one black, one white. Can someone look under their hood and tell me where those two lines go on their motor? One's a source, and the other goes to the heater switch (I think), but I don't know which is which.

Thanks in advance,
Mike

check your email...black should be vacuum source(manifold) and white(gray) should be your heater valve.
