Done. It is wired the same as 5u3's drawing. Apologies for redrawing the diagram in yet another way.

I verified that your diagram matches mine. Looks like my interpretation of 5u3's drawing was correct.

this is confusing as hell
when u say "looking into the ps/2" do u mean the ps/2 bracket adapter.. or the the mouse cord/cable?
im gonna assume umean the bracket adapter..
im having difficulty getting thsi to work on my 486sv2gx4
i had the part PLATE6F from startech .com when i received it i found out its the wrong pin layout + size (2x5 instead of 2x4)
so ive removed the wires and im sticking them directly on the pins myself by hand.. i cant get it to work..
my wires are yellow,red,brown + green.. no blue wires + no orange wires.. i dont know which color is which... I think 1 = yellow?
