I'm so glad i found this xdf. I previously used the 12202088 xdf. This is much nicer.
Is there any way to add A/C pressure based fan control with a cycling type system. From what I can tell only a few 05 trucks have that type of system. Pin 14, used for the pressure switch input is not used for anything else, even on the cycling switch type systems.
I've tried to look at diassambly but never really got the hang of it
