Dash Lights For 47 Automatic Heater/Defrost

[Bill Ingler #7799]

 It has been 10 years since I rewired my 47 and have forgotten where do the two bulbs, that light the heater/defroster part of the dash, get their power. No wiring diagram I have or have seen, show these lights. Since the 46-47 Automatic Heater/Defroster was not standard to all 46-7 cars but was an accessory, maybe this was the reason for not showing these lights in the main dash wiring diagram. Any ideas as to how these lights get hooked into the dash lights. Trying to help Dr Nasser get his 47 finished so any help would be much appreciated. My car is 15 miles away in another garage or I would look at my own car. It would seem to me that these two lights would be tied into the dash lights and controlled by the #6 position on the headlight switch which has the rheostat for the dash lights but where is the tie to these two lights ?    Thanks  Bill
