Pcm pin data
 

Hi Guys im new to this forum and in need of some technical help , Im running a LQ9 out of a 2005 escalade which I believe may have run a viscous fan , im led to believe the pcm has the ability to run a cooling fan? does anyone know if this was ever a possibility and also does anyone know where I could get pin data for the pcm from ?

any help is much appreciated
