klima Rpm boost ?

[fluk3]

when i turn the air conditioner on it gives a signal to the ecu, to raise the idling a little bit because the climate compressor must be pulled around.

So there must be a wire running from clima box to ecu is there anyone there knows what wire it is ? so I can turned that funktion off

thanks christian B
