Not sure what you are asking for.
3 heat and A/C vacuum?
Are you talking about the 3 lines from an A/C manifold guage? Or
Are you referring to where the hoses mounted in the engine compartment?
Do you have original A/C or aftermarket, and 6 cyl or V-8?

its v-8 factory a/c.im talking about the 3 lines coming out of firewall.I know 1 goes to intake and other 2 go to heater water valve.But im not sure which one goes to which.only marking is a red line on 1 line
Im guessing you are talking small block, with heater hose going to intake.
I have a pic here of my FW stripped, but its a BB w/o AC. I'll see if I have a pic of a complete Small block with AC.

I cant find a good pic of a complete small block installed in a 69 Dart, with AC.
Maybe someone here can share their's?

I would also love to have a schematic for the HVAC vacuum lines. Mine is a 1970 dart. But im sure they're the same.

yes i think they are.mine has 3 vacuum lines coming thru firewall,1 to vacuum cannister and it goes to engine and then
2 to heater water valve
2 to heater water valve
Thats how my car is. The solid black hose is vacuum supply. And the black/red stripe and black/white stripe go to the valve. Currently my valve will open but it won't shut by itself. There isn't any vacuum supply to it.

I know I'm a little late to this. Maybe it can help someone else.
These are for 1968 Valiant or Barracuda but they may work for Dart and possible 69s also.
I added an electrical diagram also. This are form 68 service manual.
