Where should I ground my bridge?

Where should I ground my bridge? My bridge is a schaller 456 :-\

In the bridge route where you screw it to the body, there should be an extra hole that goes straigh to the control route.
You should solder (or just press between the bridge and the wood) a cable from the bridge to the control routing.
Then, you shold solder the end to any ground spot below your pots.

Hope this helps.
If not, write again and when I get home from work, I will explain it with pics.

Cheers,

It all depends on the style of the bridge and where the mechanics of it would not strain or weaken a solder/wire connection.  On a vintage style the wire is soldered in the trem cavity to the claw, which is the only part that isn't moving.  On a tune-o-matic, on one of my guitars, the wire is firmly attached to the closest bridge post to the control compartment.  I checked out a picture of your bridge, and just like mo-ruiz said it would be attached to the bottom of one of the posts. You could probably pin the wire down as you are tightening the screw, then the other end of the wire would go to the main ground of the control compartment.
