I got a sunkey fusion, which way is best to install it on the website theres 3 methods one that uses the flex cables (sunkey mode) and connected between the dvd drive the other clips onto the dvd drive (d2sun mode) and also fusion mode which needs wires to be soldered. Also it didn't come with the switch and flex cable for setting the disk drive speed is this required?
