Since both you guys sound like you know what you are talking about, I'll ask an off the wall question. I got the combination gage that was standard on the early 911 from a teener in a junk yard a while back for $30. I liked the idea of being able to actually see oil pressure and oil temperature. I tried hooking up the oil pressure gauge to the standard VDO pressure switch/sender and it read about 1/2 actual value. Could I install a resistor in line to compensate for this, or do I have to buy the 911 sender? If I do have to buy the sender, do any of you 911 experts know if they have the combination switch/sender type? This combination gage has a spot for the oil pressure light as well as oil pressure gage.
