Moving forward on this. I should be getting a factory Isuzu gauge cluster that has a tach later this week. What connects from the pick up on the injector pump to the tach, is it simply an electrical wire? I think I will be able to "calibrate" the tach somewhat based on what others have done. Any information would be greatly appreciated.
