Wiring Pump

I have a Swiftech MCP655-B, and it quit working, I wanted to make sure the wiring was right, it has 3 wires, yellow, black, and blue. I think blue is the speed controller, does it have to be used or will the pump run with just the yellow and black wires?

Yellow is the monitor cable, thats for the M/B to read the speed of the propeller. Black is ground or neutral, blue is active.
A pump has a constant speed it does not change as long as its connected to a 12vDC source it will work..
Swiftech pumps have a high fail rate after 8-12months i would throw that out and get a better brand. Unfortunately i only know of one other which is Thermaltakes brand. They are good pumps but also have a high fail rate after 12months.
