Fan controller missing power cable help!

[hyperseven]

Lost the power cable to my old Akasa 6 fan controller (AK-FC-08BK).

If I remember rightly it was a molex to a 4-pin jobbie, a bit like a FDD power cable but tried that and does not fit.

I have stripped an old molex->FDD cable but just need to know which way round the 12 and 5v pins should be.

(from the pic)

12v
-ve
-ve
5v

Or

5v

12v

12v on the bottom. You can tell because of the huge PCB track to handle the fan load. The puny 5v track would only be good enough for a low load such as for a LCD or LEDs or such things. The zener in line also suggests the main rail is here.

Cheers fella

I understood part of that

So red, top, then black,black, yellow.
