Prolly just have to switch the wires around. On each 4 pin connector, there is a red/black - those are your power wires. Leave those alone. Then you should have a blue/purple and a yellow/green. Now heres where I forget what you need to do exactly, but you can experiment. Try swapping the plugs. Meaning put the entire 4 pin Red/black/yellow /green where the other one is and the red/black/purple/blue where the other was previously. If that does not work, put them back where theywere initially and just swap the yellow/green pins within the plug and do the same for the blue/purple. You'll have to use a thin tip screwdriver to stick in the slot to release the pin from the housing.
