That's a PWM fan, unfortunately you can't directly connect the bugger to any connector without losing the PWM control and getting a high pitched whining noise.

But if you want to

Pin 1 is GND (Black)
Pin 2 is 12v (Yellow or Red)
Pin 3 is SENSE
Pin 4 is PWM

Connect Pin 1 and 2 to corresponding Mate-n-lok, or if you want it neater, you could crimp it to an original Molex KK.
