Default Re: Another dumb 1937 Ford question...

Have you looked at the wiring diagram? There is a switch for the instrument lights. The wire leading to the switch is "hot" when the steering wheel light control is in any position other than off. To check it I would switch the steering wheel light control to the parking light position and see if there is power into the under dash switch. If so, then check the other side of the dash switch (the out to the instrument lights) and see if the power turns on/off with the switch. It was my understanding that the under dash switch was originally a toggle switch. And there is no dim capability.
