66 Cuda Oil Gauge

Once again you guys nailed it. The unit is a switch not a unit for a gauge. The ohms between the tip and body of the sending unit are around 40 before starting the car. Start it and there is no ohm reading. Once again I forgot a rule. Never assume the part on a restoration is the correct one to replace. Someone else could have put the wrong part there and you are just duplicating their efforts.

Thanks again! Here is a photo of what the unit looks like and the Standard box part number.
