Does a Chilton's Jeep manual tell you where your vacuum lines are supposed to connect?

[little miss frustrated]

'90 Jeep Cherokee with a disconnected vacuum line, I don't know what it's supposed to connect to. Will a Chilton's Manual give me my answer?

try cranking motor and spraying around top of motor with wd40 or a choke cleaner it will suck into motor telling you where something is leaking you put a hose on it should be able to hear is suck air

not in my experience with CHilton guides

find a similiar jeep and take a look under the hood
