I did some more research and finally I solved the problem with the oil light.
I can't believe it, but it turned out to be a broken copper line in the instrument cluster PCB.
It is a tiny, invisible pretty much, crack. I found it with the tester because it didn't make sense I had the right stuff at the connectors but the light was not on *ever*.
Anyway, that is fixed.
The lights for the instrument cluster were all gone, all 6 of them!! talk about weird stuff.
Oh well, at least, now I have the oil light functional and it was easy enough.
More soon...
