hi guys i'm new here and i need some help here.i figured how to install the s-afc,but i'm not sure about the s-afc 2.becuase there's one wire for knock sensor and 2 more wires such as the pink and the orange one for karmann..i dont really get what that means.
s-afc 2
Red - Power
Green - RPM
Purple - Knock Sensor
Grey - Throttle Position Sensor (TPS)
Brown - Ground
Black - Ground
Yellow - MAF output (non karmann)
White - MAF input (non karmann)

OR

Pink - MAF output (karmann)
Orange - MAF input (karmann)

and i dont understand what karmann is,can anyone tell me.or i'll just go with the yellow and white like the first s-afc?i've located all the wires no problem,but the purple one(knock sensor).i dont know what this wire should connect to the ecu.i have some pics for the ecu diagram.if anyone knows.please tell me which one is it.i'm new here.wich i can have someone to help me here.thanks

That refers to an old sensor that none of the IS cars have. Older Lexus cars had this kind of air flow sensor.
