Remote brake booster help



Hello,
I need help with my brake vacuum lines.
I got my 1976 p500 300 six np435 4 speed back on the road recently. Thanks to @dmptrkr and @bobj49f2 for helping me get rims to replace the Widowmakers.
Now that I've driven the truck a few hundred miles I sure would like some better brakes.
I sent the booster to get rebuilt. When I took it off it had two hoses coming off, one going to the manifold and one going nowhere. I refitted the manifold, blue line in pic, but don't know where to run the other on to, goes to red arrow.
Tia
Same brake booster hooked up the blue don't know where to run the red

The other hose is a "vent" if you will. You should hear a "woosh" out of it when you press and release the brakes.

On F series trucks, the hose was routed up into the cab behind the drive seat, a semi "clean" area out of the way.
