Okay so i found this cable hanging around, nowhere to call home. Its a four pin Molex, but only has two physical pins. What is it and where does to go? I connected it to the power supply. The usb lights went on... Nothing else

Hey I just finished my PC build, but there is no light at front panel (beside the red light in the power button). I can´t turn the big red metal bar inside the case on, either. My fan controller button at the front panel, is also out of function. The last thing is, that my system fans wont spin. Both the two intake and the exhaust. I new to this PC building universe, so only noob friendly answers. I may be doing something wrong....
