CUTLASS LS swap Question heating/AC vacuum controls

[nycutlass]

Attached is a picture i think i should feed with vacuum from the intake to get the levers inside working again for the heat and AC ? also i noticed now my heater fan isn't working I'm wondering if i left something out or i pulled a wire apart inside somehow.

On my El Camino the ball is on the driver side front. I’ve fed vacuum to it from the manifold, but I think it’s too much. It’s making a lot louder noise under the dash than I recall from the 305. I’m not sure where else I can connect it to in order to reduce the vacuum draw.

Nothing wrong with too much vacuum in that system.

I'm going to give it a shot and see if that makes the levers work again

I'd like to hear how this turned out. I'd like to get full heat control back, not just having warm air out the defroster. When I got my Malibu, this ball was broken, and I wouldn't mind fixing the heating system.

i did a LS swap on my 83 cutlass and connected vacuum to the purple hose/tube shown in my picture everything works like it used to again. very simple fix to get it all working
