M50 A/C system wiring.

[daniele30]

Hie Mate,

I'm having E30 94' E34 M50b25 without EWS with A/C system.

as we know there are 3 wires " pin 4 , 5 , 6" is for A/C.

if i would like to connect the A/C signal wire onto the ECU to increase engine RPM during the A/C functioning.

May i know which pin to connect from E30 2 pin connector (under driver dashboard) to E36 connector plug ??

Thanks.

You dont need to do this really, ive run aircon on 2.5 and 2.8 engines and the idle speed is not affected by the compressor

oh thanks for the reply.... i didn't use it but somehow i can feel the vibration when a/c system. i think it would be better if i connect it.
