- High oil level got up to 19 mega Ohms
- With the sensor pulled out of the oil and wiped, it showed 8 - 10 mega Ohms
I may take the experiment a little further when I have time. I don't expect to find a 15 M Ohm resistor in my parts pile, but I may find some that I can put together in series to see what happens either connected to the sensor connector or directly to the cluster and ground.
If my readings and guesses are correct, you could solder three of these 4.7 M Ohms together in serial and connect it to pins 2 and 4 of the connector and get an acceptable oil level indication. (  eBay) I could easily be wrong.

Outstanding it sounds like you could be right also. I have several more items to button up before I start the engine and I also have to make a trip this weekend so I won't be back to you for a while. gives me time to order the resistors. Thanks for the help.
