Yeah! thanx, i found it too...but after posting my question! :-) But a video would be great, a bit afraid to damage my mac...thanx

Done, your link was ok!:) difficult to plug the tiny wires...on a Mac Pro early 2008, you must plug wire 1 and 3, the longer one at the bottom, the smaller one at the top....worked right away....p.s : take a little time to clean your Mac, you'll be amazed with the amount of dust !
