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.

I need to know what circuit(s) control the dash lights, O2 Sensor diode, and
heater switch light.
