I think that goes to the ball, the accumulator.
It's like an air tank for vacuum.
I would just plug the line for cruise control
 
Link shows big hose goin inside cab to brake thingy at bottom of floor, its the vacuum release
 
Since ill be cleaning up vacuum lines, i believe i only have gas tank vent line hitting charcoal canister, all other ports are plugged.

Should i route one to carb for carb vent/over flow ? Carb is holley 570cfm

Has anyone just eliminated cannister all together ?
 
If you eliminate, evap canister you may have to use a vented gas cap.
 
If you just plug at manifold, will effect the the heat and AC controls. They are teed into the same line and use the ball also.

The vacuum line that goes through the dash is connected to the cruise control switch. The cruise control switch works like the brake light switch. It has a spring loaded plunger that is activated by the brake pedal arm. The switch is used to turn the cruise control off when you step on the brake pedal. You can just leave the vacuum line hanging, and it will not effect the operation of the vehicle, unless you want to remove it, in order to give the engine bay a cleaner look.

I removed my cruise control as well because I have a TBI adjustable fuel pressure regulator. The regulator set up required modified fuel lines and a gauge that needed to be located right where the cruise control diaphragm was located. The cruise control diaphragm also blocked access to the adjustable regulator set screw as well.

The cruise control module can go almost anywhere if you attach a cable to it. Granted there is a limited range if you don't want to lengthen the wiring harness. Mine is in mounted over by the DS fender (stock wiring). From the 90's on up, most cruise controls used cable drive, so there are various cables to choose from off different vehicles that match one of the short list of throttle connections GM used.

That is a good idea. If I ever want my cruise control back I will do what you recommended.
