I have a wiring diag & manual for S80 Bifuels, unfortunatley it's not in English, it's in (don't mention the war... ). Only got it a few days back, and I've not had a chance to scan or translate it. My (beach towels at the ready ) broken German can see relay FMA2 is the master power relay to all that is Necam. In turn FST02 fires the DFCO. If those relays are not firing (or the output for the CPU is not there because the temp stat is not firing an output), your car won't switch, but the fault is usually the stepper. That theory was blown sideways by a bloke I'm dealing with now. In his, he'd had some baboon of a previous owner hacking at his car.
