Heater diverter valve question.

Hi, Iv'e done some searching and can't find an exact answer, basically the heater diverter valve on my car is hooked up except for the vacuum(?) line that comes out of the top of it, I have no idea where it goes? Maybe a firewall vac hose of some sort? Any help would be appreciated! Pictures would be amazing!

I came to this when I was trying to undo all the vacuum hoses that were hooked up incorrectly, followed others diagrams and pictures. I got them all done except this one, thanks in advance guys(and girls?).

Re: Heater diverter valve question.

Pass side firewall, beside the heater box itself - kind of on the driver side of the heater box - there will be two vacuum lines inside a harness that also has wiring for the blower motor - one is an inbound line to take vacuum to the heater control switch, one is an outbound hose to take vacuum to that heater diverter valve.
