Every car is different, but generally you want the fitting to be as much in line with the port where the hose enters the wheel cylinder or caliper as possible. What you are trying to do is keep the hose from getting pulled tight as you make a turn one way and from having too much slack when you turn the other. You also want to make sure the hose will clear things like headlight mounts, drag links, shocks, etc. when turned sharp each way.

What you might do (if you don't have your brake hoses yet) is rig up something like rubber fuel hose and temporarily hold it to the wheel cylinder and several spots on the frame to see where it will swing the best when you turn the wheels from one side all the way to the other.

It might help if you post some pictures of your setup so we can visualize better exactly how yours is set up.
