Help with air ventilation controls
 

Hey everyone
I own a 2003 rx8 which was a jap import so came with a factory radio in it being a bose which was great but I have recently upgraded it to a JVC head unit.
my issue that I have is that everything ran through the bose stereo unit like hazard lights and air ventilation controls in some way. With me replacing the bose stereo I now need to get the ventilation system going again but am unsure how to do it.
I had to splice my hazard controls into the wires too so that they worked.
is there a module or some way I can wire up my air ventilation system again.

any help would be greatly appreciated
