vent vaccum lines, forgot which ones go where?
 

I replace my ac evaporator today and have everything back to normal except connecting the vaccum lines back in the right place. Yellow, Red, and Brown-which line goes where?

one place---top silver canister
second place----bottom silver canister
third place-----on the side of the bottom canister

I've tried every which way and cannot get the air to blow out of the vents. Just defrost and floor. I have vaccum on the yellow on max cool.

Thanks
