Any ideas from this point? - like helping me trace the wire to where ever it goes?

Don't make it hard on yourself. Disconnect the wire at the oil pressure sender. Turn the key on. The gauge will peg at 3 bar if it's like mine. With the key still on, ground the wire you removed from the sender. The gauge will drop to 0. You've just vetted the gauge and wiring. The only thing left is the sender, which I'm guessing has an open circuit somewhere between 0 and 1 bar.
