Thanks for trying to provide a thorough description of your symptoms. You have, however, failed. What light goes on? Is your oil level OK? Punctuation would help. Having said that it is risky to assume, on a car with 228k miles, that you have nothing but a gauge problem. I would get the oil pressure checked right away.

Glad you got your problem solved. My lower harness (300E) did the same thing a few years ago, and the dealer doesn't stock a replacement. So I MADE a new one.
In my case, the bare wires shorting out on occasion ended up ruining the oil pressure sender, so I had to replace that too.
