Yes, pix with hands in them suck.
Pin 39:
Pin 39 wire run to clutch switch, clutch switch tapped into brake switch:

Does someone know that signal black/brown wire of the brake switch (for clutch switch tap in) carries?
Here is my brake switch connector: the black/brown (red?) wire on pin 4 has ground with brake pedal up, and 12V with pedal down.
Same on the B6 switch cable?
Clutch switch is CLOSED with pedal up, opens when pedal is pressed down.
The ECU gets:
When connecting the 2nd pin of the clutch switch to the red/black brake switch wire (pin 4):
both pedal up:
Ground to ECU pin
brake down:
12V to ECU pin
clutch down:
open (neither ground nor 12V)
both pedals down:
open (neither ground nor 12V)
