in-cab A/C vacuum line functions/connections?

Not long ago I had to completely remove my dash to get into my evaporator housing (you don't wanna do this.) Things went back together well... over the ensuing weeks...but one of the lingering questions is where the RED vacuum control-line was supposed to go. Doesn't seem like there's any obvious, or even un-obvious vac operators to connect, and it's possible this line wasn't connected at all before - just wedged up somewhere - but surely it came from the factory with a connection to something. All A/C functions seem to be as they should (though I gotta say, having seen the guts of the A/C controls, this looks more like something engineered in Bedrock than in Tomorrowland.)

Red vacuum line goes to the heat/defrost act. It should have two vacuum lines on it, one brown the other red. If you follow the brown line it should lead you to the correct act.

Thanks, Busboy - there's two connections, as you may have known, to that same actuator, with one nipple hiding on the back side, jammed up against the firewall, where I'd not seen it before (until you made me lie on the floor with flashlight...) Can you confirm that the brown line actually goes to the one facing the firewall, and the red to the nipple that points at the pedals? They're both about the same length and I could believe either way...

Unlike your truck, my 01 is still buried in snow and I couldn't remember which one went where, so I went out and cleared a little snow to get in. Red vacuum line goes to the fitting closest to the pedals, brown towards the firewall.

Busboy - Excellent!

Thanks for the trip out into the snow, too. Could use a bit of that cooling here - it's been still, humid, multi-showers-required-per-day weather here for several days now. Hate it like this.

Just after 9/11 I was sent to HNL for 3 months, stayed in Waikiki. I'm sure it rained on and off almost every day, to you it's just rain, to me it's "liquid sunshine".
