weird 6 pin connector (maybe for a MAC)

odd ball wiring, so far I know that with the pump flip upside down that the first one(on the left) is +, and the next to last one is -

Weird..

One is probably an RPM sensor. If you have a multimeter with HZ, you should be able to detect it with the pump running (Hz x 30 = RPM) at least for fans. Perhaps the other is a PWM control??

I've seen more than a few pumps here like that and the only conclusion I can come to is, odds are pretty good it's a MAC DDC of some kind. I say "some kind" because the plug doesn't seem to match the pics of MAC DDC's I can find on the net but the wires definitely do match.
