Here's the way it is on my machine. The extra wires you have probably go to the card cage security switch (it might be removed in your machine). The security switch is shown in this photo but the wires are disconnected. On the pushbutton diagnostic switch the wires go to the center terminal and the Normally Closed (N/C) terminal. That way they BREAK contact when the diag button is pressed. Your diag switch could be mounted a different way so don't assume the switch terminal on the left is the correct one. The terminal labels (N/O, C, N/C) should be written on one side of the metal part of the switch. Both wires connecting to the switch should come from the same harness (mine says "P3"). The other wire harness is for the security switch.
