there's a major misunderstanding here, the colors on these startech headers are completely arbitrary and it's always mandatory to check each invidiual one. on mine it's red GND, brown data, yellow VCC and green clock, but many other variations have been posted here: PS/2 Bracket for Asus Motherboard Header
what i've done with mine is to remove the black plastic piece and just put same color jumper wires on the pins, isolating the connections with electrical tape, so that i can use the same header on different mainboards without hassle. the little plastic tabs holding the pins in place tend to break quickly anyway after rewiring 2-3 times.
