How do I install a switch that controls the fan's speed?

I saw a link to a website before that showed how to wire up a switch that can send the 12v or a lower amount of volts. Does anyone have a link to this website?

That's a great little guide for a 7v / off / 12 volts baybus...(i built one myself)

but if you want MORE voltage steps, check out virtual hideout's rheostat baybus guide
