Dodge Hemi Can bus message for controlling A/C compressor

I did a  2012  5.7 swap into  older pre-can Bus car.   Using 2008 - 2012 Can bus PCM .    I need to activate the A/C compressor  via a CAN bus message.

Does anyone know the MSG ID  required to be sent to PCM to activate the A/C compressor. 

Thanks in advance  !!
