It's an ECS P4VXMS. Here's the diagram as shown in the manual. Now this is where I got confused. For example the Green LED has got a green wire and a white wire. Should the white one go into pin 2 and the green one into pin 4 or vice versa? Same goes for the: - Power which has got a blue wire and a white wire - Reset which has also got a blue wire and a white wire - HDD led which has got a red wire and a white wire I've been trying endless combinations and all I've been getting is very long, slow beeps.
