Mk6 spin button died

[Don Indallas]

The spin button on my mk6 stopped working. The button will light up, but does not respond to being depressed.  You can hear the switch click, but no response.  Moving the wire plug causes the light to go off and on, but the button test won't show it works.  I suspect something in the harness.  Dies anyone know what should be present on each of the wires connecting the spin button?

I found it is not the spin button or the wiring.  It is on the I/O board.  There are two transistors that allow the function of that button and one more for the lifgt. I don't know which two are for the function of that button.  Does anybody have any information on which transistors are associated with which button?
