I believe the stock BCS is 12V that's comes on with the ignition. Not sure how well it can handle a fan though.

I believe the fan is simply controlled by that switch that is threaded into the bottom of the radiator on 1G's. Kyle mentioned something about being able to buy switches that thread in, but switch on at a lower temperature. Have you tried putting in a new switch? That may be worth a shot, and shouldn't take too long to swap in.

Also, just a dumb question, but are you overheating or anything? Do you know that the fan isn't running when it should be running? If it's not even getting up to the correct temperature where it should be turning on at, the fan won't kick on.

And yes, the passenger fan is the MAIN fan.
