On my 2.1, I assumed the "old" looking oil pressure switch was
intermittently causing the
oil buzzer and light to turn on. Turns out it likely wasn't.
My theory is that wire corrosion on the brown wire from switch to white
connector added enough resistance to trip the L board.

In hindsight, I should've taken time to replace the terminal at switch
with a better suited
type. i.e. the same type as OEM. But the connection to switch is clean
and physically stable.
