Is the fan 4 wires? or is it 2 wires on the fan and 4 wires between the two molex connectors?

If it's just 2 wires to the fan (as I suspect), they should be the red and black. You need to either find a female DC power connector that fits your power supply and wire it to the fan. You can also just cut the end off of your power supply and wire it directly to the fan.

It does not matter which wire goes to which. If you reverse the wiring, it will reverse the direction of the fan (so make sure it's flowing in the right direction).
