that black cable that u see going on top of the intake....it doesn't connect to anythign, i always wondered if it was suppose to connect anywhere, but my intake has nothing for it to connect to...

about the plugs...i had mine checked at the shop...so they unplugged the top plug, and stuck some device into teh green plug (i guess it completes teh curcuit and the fan started spinning) so he knew right away taht was bad

then the front green plug, he did the same thing, but nothign happened, but in teh end he concluded it was the top one, so i went home and changed it myself, and it works fine now

i was told, to unplug the green plug...and plug a paper clip into it, so teh curcuit completes, that way if the fan starts to spin, u've found your problem....most likely that is the problem..to be honest with you, if you want, just change both
