The dash and heater switch lights are controlled by the headlight switch and the rheostat in same. They are fused. The o2 warning light has a bit of a dual function. There is a mileage counter that urns it on at ~30k mile intervals to let you know it is time to get the O2 sensor checked-tested. In addiditon it also turns on with the alternator warning light to act as a bulb check. The circuit is a little different for the campers as the alternator warning light circuit is also used to operate the fridge 12 volt relay.
