Vacuum headlight lines, power brakes and aftermarket cannister

[timmycharger]

I am not using my factory headlight canister, instead I am using an aftermarket one from Crane. Is it possible to use the can for the headlights as well as to help the power brake booster? do I just put a T in the large hose that comes off of the intake or will the one way valve stop it from putting vacuum back in the booster? The canister has 3 holes in it, 1 big, 2 small. The big one is for the intake, and the small one is for the small line off the vacuum harness. Has anyone run this set up before? I cant be the first to try

The headlight canister is there to provide reserve vacuum if you forget to shut off your headlights after you turned the car off.  So the headlight doors will close when the motor is off.
