Hello everyone,

Hopefully someone can chime in here and give me a hand. I have a friend with a 2001 A4 1.8t we converted auto to manual. All works good but wanted to add nls/lc but car has not clutch switch, had it running off brake switch for a bit. We installed clutch switch today, but lc does not work. Curious which switch b_kuppl uses, I am assuming its the cruise switch which is what we hooked up to pin 39 in ecu. If it is the other clutch switch(start inhibitor), please help as i dont see where it goes to the ecu anywhere. I appologize if this is in wrong section. Thx for any help, love this forum.

and from my understanding you only need to supply 12v to the clutch switch pin hence why you tap it into the brake pedal switch
or i suppose you can run a wire to a switched 12 v fuse

open circuit is clutch engaged 39 shirted to ground is clutch depressed 

CWKONFZ_1 +1 (make sure it's even).
OR correct ECU coding, if it's "recodeable" for AT/MT.
