Hey guys, informative thread.

I am doing something along the lines of this however I need a little insight on the following, hopefully someone on here can assist me.

When wiring the clutch switch module (which I am not running)

There are two wires that go to the CAS one to the DME, one that tells the DME the clutch is slightly depressed, and one that tells the DME/CAS when it is full depressed.

I am curious to know which is which, I have attached the diagram.
From my research, the clutch module has 12v in, ground, 1.5-2.5v out for the clutch slightly depressed (tells the DME when to cancel cruise etc) and then 12v out which goes to the CAS to tell it when the clutch is fully depressed for starting the car.

I just need to know which of the wires going to the CAS I am supposed to feed 12v to start the car (either pin 3 or pin 41)

Does anyone have any insight to this?

Thanks in advance.
