Heater control lights?
 

A PO removed some of the wires to the lights behind my heater control panel (on a '73S Targa). How are the four lights behind the panel supposed to work? Do all four (the lights behind the red and blue squares in the upper two corners, as well as the lights behind the words in the bottom two corners) come on when you turn on the lights, or do the two lights in the upper corners only come on when the fan/heater is turned on?
