S90 T8 HVCH(high voltage coolant heater) to CPM (combustion preheater) swap problem

[Power6]

Hi again!
I finally figured it out! All wiring was good. It turned out since my s90 is made for us market it had different spec cem also what was missing some components. I ordered different cem from eu car, made clone of my original cem, put everything back together and woila! Climate relay works! 
Its sooo stupid that engineers are willing to make so many different parts for just saving couple of cents.. 

I am not too surprised...they are willing to save a few cents on those components not needed, if at all possible.

This was a nice swap, must have been much work! I find it interesting, that the HVCH is a "new" type of thing for EV and PHEV cars, but for Volvo, they just mount an electric heater where the combustion heater used to be ;-)
