Air Grabber

When hooking up the 2 vacuum hoses to the electric solenoid in the dash...which hose goes to what fitting or does it matter? (1970)
Thanks in advance

See below

On the can there is a green dot on the center nipple, which the hose with the green tracer connects to.

On the illustration showing the solonoid... there is two nipples for either hose.(black or yellow) The nipples dont state which hose goes to what. Does it matter? Thanks
