Hello experts, would like to finally activate the oil pressure gauge in my Saab 9000 CS ECOPOWER, 125 kW. To do this, the serial pressure switch for the warning lamp in the dashboard has to be replaced. But how is it removed? Is there only one plug plug on the thread socket and can you just pull it off? I tried it, but the thing is damn tight. Wouldn’t want to destroy anything. Or how else can it work? Greeting, julefreund
