aux. cooling fans

I'm putting a 10 blade cooling fan from a '99 into my '90. does anyone know the proper polarity and colour code of the wiring?

Black is most always a ground, in American cars. Red is often a hot wire. With a stripe, is often switched current or a control circuit.

In my '96, the white wire was (+) and black (-). This was consistent with the flex-a-lite fan I installed that used the same color scheme. In some fans, if you reverse the wiring, the fan spins the opposite direction. That's another way to tell.
