Just bought a new case, mb, and processor, and was looking at what had to be hooked to what. This is my first time doing this kind of thing. I have upgraded disk drives, modems, software, etc., before, but nothing from scratch.
The case is a Min Maw 3713.
Anyhow, there are 4 mini cables dealing with power, HD light etc.
3 of them are terminated in a 2 wire connector and even I will be able to figure out how to connect these. The 4th is a 3 wire connector with the middle position open. I don't recall what the colors were, but the plug-in on the motherboard is only 2 pins.

Before I take the wire cutters and soldering iron to the cable, has anyone run across this and what have you done to solve it ?
Does it make a difference which wire goes to which pin ?

Thanks so much, and wish me luck.
