It was described above (I haven't bothered to check the TIS to confirm) as a power and 2 grounds to the ECU, one starter interlock and one to inform the ECU of clutch location for engine management during gearchanges. The single hall effect switch would trip both grounds every time the clutch pedal is down. If you don't want the ECU to know the clutch is disengaged just remove the wire from the bundle that transmits that info to the ECU. I'll be checking into this further this week.
