I was just looking for a simple patch instead of cutting the wire and running a new one from the starter as this was never done on this car. You have a good point about driving up into the mountains in the winter but if all I have to do in that case is reconnect the snap on connector then I'm ready to go. I don't have any evidence that the injector is faulty but since Volvo went to the trouble to issue a service bulletin then I just assumed that it was a troublesome design in the first place. Also I was getting the OBD code 3-2-1 which indicates a missing signal from the cold start injector even before I thought about disconnecting it.
