Re: VRO Wires?
one wire attaches to the brown wire coming out of the wire harness near the red plug.
the other can go to a clean engine ground.
assuming its an original tank? the low oil warning should beep the horn every 20-40 seconds when oil is low approx 1\3 left in tank.
too say those sensors were problematic would be an understatement. Everything from not working to erratic horn soundings.
