91 Volvo 960 B6304 Motronic 1.8

It turned out to be important to connect all the ground and battery voltage pins. #19 GND Signal #24 GND Power #30 GND Sensor

#18 +12V 30-feed #27 +12V 15-feed #37 +12V 15-feed from main relay. (This creates smoke if the others are not connected.)

i am quite interested in seeing what you are doing, andgiving the ecu a closer look myself.

so any further info (assuming you get it powered-up) would be awesome.
