Cav b204 is nearly done. Recently I was fighting with wiring. I used diagram from saabrally. I got +12v on pins 1&48 and +12v ignition on pin 60 and I got power supply on injectors and coil pack, but I don’t have signal on coil pack or injectors. Anyone know how to sort it? I wired OBDII thru k-line but I can't connect to ECU. Any ideas?
