Good Tutorials on Using the BS2 for 12v Motor Control

I'm looking for a good tutorial on how to use the BS2 to control 12v motors (High Amps like an electric car window motor)

The part that confuses me the most is the isolation of the BS2 and the Motor Control Power - I don;t want to blow up my module as they are hard to acquire where I live.

Any help would be great! Thanks.

    Big current needs big SPDT automotive lighting relays, wired in H-bridge as schematic shows.

    Cactii,

    I'm using the Parallax HB-25 to drive two power window motors wired in parallel. They are very easy to use and the same commands that drive a Boe-Bot servo will drive the HB-25. Relays work fine if you need only full speed, but if you need variable speed, go with the HB-25s.
