My oil light does not work. I have replaced the LED light in the dash, and
I know it is good. I took the wire going to the oil sensor off, got a
wire, and took it to ground with the key on. No light.

Where the connector in the dash , plugs into the harness, which wire is
it, that feeds that LED?

I am going to run a wire from the motor to dash.

I need to know what wire it is that powers the LED,and splice into it ,to
see if I have a bad wire going from the dash, to engine.

I hope someone has a clue, on this one, hate knowing that the idiot light
is not there to warn the idiot behind the wheel(mainly me), and then I
blow up the motor when not looking at the aftermarket gauge
