I just had to buy a key start for my 2004 wr450f and I don't know what the wire colors mean for the bike itself.

It's all layed out in the service manual, which you can download off of Yamahas website.

Black is ground.  Red is constant positive.  Brown is positive when the ignition button is on.  So you want red and brown from the ignition button.  Unless the 2 wires connect in the key off position.  Then you hook it up to the kill switch wires.  Or if it's a 4 wire switch, you can hook it up to both.  I don't have a 2004 though but it's probably the same.
