This is an awesome confirmation about the "Mod/Mod" Heater Controller (my modual is date stamped '87) for late model Carreras (87 -89) with manual heating systems . I'll look at the thread to id the exact aftermarket relays to replace the entire control modual pcb board. I think it is important to reiterate that this is for those who will use their original working engine blower or with a "Wavey mod" like mine and use their FW blowers. I don't know why my jpegs won't upload. Thanks for your help.
