I have a drawing of where the hoses connect onto the heating/ac control unit in the dash, but it doesn't clarify which is which.

Does anyone have a drawing of this to clarify.

I'm trying to solve the same mystery; where are you lost? Perhaps we can help each other.

My part is under the hood; I know where to connect the vac source line, but not to which of the two line coming out the firewall. Was going for trial and error; whichever makes the air route to the windows again is the winner

i just need to know what color hoses go on what on the heater/ac control in the dash.

Willcox has some excellent schematics and repair help.

Have you ordered the assembly instruction manual (AIM)? The AIM shows the connector, the numbered ports, and the correct color of the hoses to each.
