Gigabyte GA-X58A-UD3R can't connect on off switch cable Just purchased this S/H when I went to connect the on /off switch cables, on my cables it is a block of two on the motherboard which is using the B setup it is 3 pins utilising the 2 outside pins how do you overcome this please?

power switch from case shoud be block of 2 on both mobo and case
power led cable is 3pin on mobo, from case it cane be block 3pin block or two single blocks

In the motherboard manual it states the are boards with an A connection which is the one with a 2 pin power connection and motherboards with a B connection mine is the B connection with a 3 pin block and has nothing connected to the middle pin
