Took another look at the VZ wiring diagram - for the brake\clutch ecu inputs. Can anyone confirm what the switch position symbols mean on this. ie. Is the brake switch NC or NO. I would have thought NO, but looking at the symbols the 2 for the clutch inputs are one of each? Wondering if the ecu thinks Im driving around with the clutch in or brake pressed all the time.
The reason Im asking is because I stumbled across this in my research:
"Also, for a manual transmission tune to function properly the PCM will require input from both a clutch switch and a brake switch."

Andy, the top three symbols are "NC - Normally Closed" and the bottom one is "NO - Normally Open".
I'd say some of those inputs are for Cruise control. The trick is the switch may say NC, but is that in the "resting" position? e.g. The pedal switches are normally "depressed" until the pedal is pressed in to the floor. So in theory the switch is OPEN until the pedal i pressed to close it. A bit confusing really. (And I might be totally wrong but its my recollection from when I did my LS1 Cruise controls switches).
