Cooling fan wiring help needed

I am installing aftermarket fans into my 2007 Exige S. The fans came with different connectors so i need to figure out which wire in the oem plug is the positive for both fans. I tried looking around for the info but could not find anything Anyone know the colors on the OEM plugs?

Thanks in advance

The cooling fan wiring on the Elige's is a little different because Lotus has them wired in series for low-speed operation and in parallel for high-speed. I'll include a link to a thread with wiring diagrams, they're for a 2005 Elise but I'm pretty sure it's all the same. You'll find the cooling fans on sheet 10. For cooling fan #2 it's pretty straight forward, the slate (grey) wire is the positive and the black wire is the negative. On cooling fan #1 it's a little more complicated but I think the purple wire with a slate (grey) stripe is positive, and the blue wire with a slate (grey) stripe is negative.
