If you have any computer fairs in the area, I'd check there for a 4-3 pin connector.

If you can't find one, it wouldn't be hard to make one yourself. The yellow wire on a 4pin connector is 12v, and the black wire is 0v. I'm not sure if there's a color standard for 3 pin connectors, but on mine, black is 0v and orange is 12v. If you have the female 3 pin connectors facing you with the connector holes at the top, the order from right to left is 12v, 0v, rpm. Just get a 3pin from an old fan and do a quick solder and heatshrink job.

You could do also switch the 3 pin connector on your resistor for a 4 pin, using an adapter or another solder job.
